Parc naturel des Plaines de l'Escaut
Laplaigne
Parc naturel des Plaines de l'Escaut is one of the largest natural parks in Wallonia, covering roughly 46,500 hectares in the Wallonie Picarde region, right on the border with France. The village of Laplaigne, part of the municipality of Brunehaut, sits at the heart of this protected area and makes a convenient base for exploring the surrounding landscapes. Which area does the park cover? The park stretches across seven municipalities: Tournai, Rumes, Brunehaut, Antoing, Péruwelz, Belœil and Bernissart. That gives it a large and varied footprint, ranging from village edges to deep woodland and wet meadows. The Scheldt river (Escaut) enters Belgium precisely within the park's boundaries and flows through it for about 15 kilometers, leaving a clear mark in the form of a broad alluvial floodplain. This floodplain, dotted with old river branches and damp grassland, gives the landscape its distinctly watery character. What kind of nature is there to see? The park's scenery is shaped mainly by pollard willows, wetlands and forest blocks. One especially notable site is the Harchies Marshes, protected as part of the Natura 2000 network. The marshes draw birdwatchers in particular, serving as an important stop for migratory species passing through during their seasonal journeys. A mosaic of habitats — open water, reed beds and wooded patches — makes the area's biodiversity unusually rich for a lowland setting in Western Europe. What can visitors do here? The park offers more than 500 kilometers of marked hiking trails, making it a genuine haven for walkers and long-distance hikers. The trails cross a range of environments, from riverbanks to meadows to forest, so each route offers a different flavor of the landscape. It's also a good spot for cyclists and for anyone looking for a quiet escape from the busier towns of the region. Where can visitors get more information? The park's office is based at 31 Rue des Sapins in Bon-Secours. That's where visitors can pick up informational material, trail maps and up-to-date guidance on path conditions. The House of the Natural Park also hosts L'Escale forestière, a center focused on the region, its forests and hiking options, along with the interactive Explor'forêt center, which explains how the forest ecosystem works in an accessible way. It's a good starting point for a visit, especially for families interested in nature topics. Frequently asked questions Is Laplaigne located inside the park? Yes, the village sits in the central part of the protected area, within the municipality of Brunehaut. Which river flows through the park? The Scheldt (Escaut) flows through the park for roughly 15 kilometers from the point where it enters Belgium. How many kilometers of trails does the park have? The park offers more than 500 kilometers of marked walking trails. What else is worth seeing besides the river valley landscape? The Harchies Marshes, protected under Natura 2000, are one of the region's most important spots for observing migratory birds.

Middenloop Zwalm
Strijpen
Middenloop Zwalm is an extensive nature area stretching along the middle course of the Zwalm river in East Flanders, Belgium, spanning the municipalities of Zottegem, Zwalm and Brakel. Covering more than one hundred and forty hectares of meadows, valley slopes, groves and woodland, it forms one of the most valued landscapes of the Flemish Ardennes (Vlaamse Ardennen). What makes up Middenloop Zwalm? Rather than a single continuous reserve, the area is a mosaic of smaller pockets of nature scattered along both sides of the river valley. These sub-areas include Boterhoek, Bruggenhoek, Bruul, Jan de Lichte, Jansveld, Moriaan, Rozenhoek, Vossenhol and the woods around Steenberg. Each patch has its own character, ranging from damp riverside grasslands to steep, wooded slopes, so walking through the wider complex reveals a variety of habitats typical of this gently rolling region. Management and conservation of the land is carried out by the local branch of the Belgian nature organisation Natuurpunt, operating here as Natuurpunt Zwalmvallei. Their work maintains grazing land, hedgerows and older tree stands, supporting the biodiversity of the valley. Exploring the area A network of marked walking paths crosses the reserve and is open to visitors year-round. One well-known route is the Mijnwerkerspad, which follows an old railway track along the Zwalm river and the slopes of its valley, linking the municipalities of Brakel, Zottegem and Zwalm. Another option is the Berendries loop, a roughly 12.6-kilometre circuit that passes the most notable spots within the Middenloop Zwalm area. Walkers can take a break at the Boembekemolen mill, where a terrace offers a place to sit and order a drink. It is a convenient stop roughly halfway through a longer walk, particularly on warmer days. Dogs are welcome but must be kept on a leash, since parts of the land are used for grazing and controlling pets helps protect the local flora and fauna. Who is this destination for? Middenloop Zwalm suits visitors looking for a quiet outdoor escape away from busier towns and cities. The combination of rolling terrain, mixed woodland and open meadows, together with the presence of the river, makes it appealing both to those planning a longer, multi-hour hike and to families wanting a shorter, relaxed walk. The Flemish Ardennes are known for their gently undulating countryside, and the Zwalm valley is one of the region's defining landscapes. Frequently asked questions Where exactly is Middenloop Zwalm located? The area lies in the province of East Flanders, within the municipalities of Zottegem, Zwalm and Brakel, along the middle stretch of the Zwalm river. How large is the nature area? The complex covers more than one hundred and forty hectares, spread across a number of smaller sub-areas along the valley. What walking routes are available? Notable options include the Mijnwerkerspad, following an old railway track, and the Berendries loop, which is about 12.6 kilometres long. Are dogs allowed? Yes, as long as they are kept on a leash, due to grazing livestock and the need to protect wildlife. Is there somewhere to rest along the way? Yes, the Boembekemolen mill has a terrace where visitors can stop for a drink during their walk.

Perlinkvallei
Sint-Blasius-Boekel
Perlinkvallei is a small nature reserve in the Flemish Ardennes (Vlaamse Ardennen), located in the municipality of Zwalm in East Flanders, Belgium, within the village of Sint-Blasius-Boekel. The roughly four-hectare reserve stretches along a scenic valley on the right bank of the Perlinkbeek stream, also known locally as the Boekelbeek. Further downstream, beyond the reserve itself, the same watercourse changes its name to Moldergembeek and later to Peerdenstokbeek before joining the river Zwalm at Nederzwalm. What is there to see in Perlinkvallei? Despite its modest size, the valley packs in a surprising variety of habitats: patches of riparian woodland, small ponds, a hay meadow, and a small orchard. This mosaic of environments is what makes the area so rich in plant and animal life relative to its footprint. The wooded sections along the stream contain pollard willows, while the forest floor and banks support wood anemones, primroses, and wild garlic — species typical of the damp, shaded valleys carved by small streams across the Flemish countryside. What animals live in the reserve? The ponds scattered through the valley serve as breeding sites for amphibians. Visitors may come across toads and frogs, along with three different species of salamander — a notable diversity of amphibians for such a compact reserve. Their presence is generally taken as a good sign of clean water and a healthy surrounding habitat, and the ponds themselves form one of the ecological anchors of the valley. Who manages Perlinkvallei? The reserve is looked after by Natuurpunt, Flanders' largest nature conservation organisation, through its local branch Natuurpunt Zwalmvallei, which oversees several nature areas along the Zwalm river valley, Perlinkvallei among them. Much of the practical upkeep of the land relies on volunteers from surrounding villages, who take part in regular management work such as mowing the meadow, pollarding the willows, and maintaining the small orchard. Is Perlinkvallei suitable for a walk with children? The reserve reflects a "nature on your doorstep" philosophy: it is designed as a place where local children can experience nature hands-on, whether in the woodland, by the pond, in the hay meadow, or among the orchard trees. As a result, it tends to attract families and school groups from the neighbouring villages, even though it remains a modest, intimate corner of the valley rather than a large landscaped nature park. Can the reserve be visited with a guide? For visitors who want to explore the heart of the area more thoroughly than a casual walk along the paths allows, guided nature walks can be arranged with an experienced local guide. Such a visit is a good way to learn more about the valley's history, its plant and animal species, and the reasons this particular stretch of landscape came to be protected. Frequently asked questions Where exactly is Perlinkvallei located? In the municipality of Zwalm, East Flanders, in the Flemish Ardennes, within the village of Sint-Blasius-Boekel. How large is the reserve? It covers approximately four hectares of stream valley. What animals can be found here? Mainly amphibians — toads, frogs, and three species of salamander, all associated with the valley's ponds. Is entry free? The area is generally open to walkers, while a more in-depth visit to its core can be arranged through a guided nature walk. Who takes care of the reserve? Natuurpunt Zwalmvallei, the local branch of the Natuurpunt organisation, supported by volunteers from the surrounding area.

Munkbosbeekvallei
Beerlegem
Munkbosbeekvallei is a nature area in the Flemish Ardennes, in the south-eastern part of East Flanders, Belgium, built around the small Munkbosbeek stream. It spans the border of the municipalities of Zottegem, Zwalm and Gavere, set in the gently rolling landscape between the villages of Velzeke-Ruddershove, Dikkele and Beerlegem. Where exactly is this valley? The Munkbosbeek is a roughly 7-km-long stream that winds through fields, small woodlands and meadows before flowing into the river Scheldt near the bridge connecting Nederzwalm and Zingem. The protected area follows its course close to the village of Beerlegem, at coordinates approximately 50.90° N, 3.72° E — right in the middle of the typical hill-and-valley scenery of the Flemish Ardennes. How did this protected area come about? The area gained protected status in 1993. Management of its scattered parcels lies with Natuurpunt, through its local Zwalmvallei branch. Because the site isn't a single continuous reserve but rather a patchwork of fields, woodlots and meadows under different ownership, Natuurpunt has gradually acquired or taken over management of additional plots over the years, aiming to stitch them into a more coherent network of habitats. The organisation has drawn up a long-term plan for nature and landscape development in the valley, aimed both at protecting existing plant communities and restoring more natural water and woodland conditions where possible. What can you actually see in the Munkbosbeek valley? The valley alternates between patches of woodland, damp meadows and farmland, a mix typical of this part of Flanders. This mosaic of habitats supports a fair variety of species — meadow and woodland plants as well as birds and insects associated with small stream valleys. The brook itself, modest as it is, acts as the ecological backbone of the whole area, linking the separate habitat fragments into a single corridor running through the landscape. Can you walk through the valley? Yes — two marked walking routes cross the area: a blue route of about 5.9 km and a red one of about 6.3 km. The red route runs entirely along paved roads, making it suitable for strollers and for visitors with limited mobility. The blue route, by contrast, partly follows field and forest paths, and is better suited to those who prefer a quieter, more immersive walk closer to nature. Both loops showcase the region's characteristic blend of farmed land and semi-natural vegetation. Frequently asked questions Is Munkbosbeekvallei a single, enclosed nature reserve? Not quite — it's better described as a network of scattered parcels along the stream valley, jointly managed by Natuurpunt rather than one fenced-off area. Who manages the site? The local Zwalmvallei branch of the nature conservation organisation Natuurpunt, which has looked after the valley's nature and landscape since 1993. Which villages border the valley? Velzeke-Ruddershove, Dikkele and Beerlegem, spread across the municipalities of Zottegem, Zwalm and Gavere. Are the walking routes family-friendly? Yes, especially the red route on paved roads, which can also be covered with a pushchair. Where does the Munkbosbeek stream end up? It flows into the river Scheldt, near the bridge between Nederzwalm and Zingem.

Cotthembos
Oombergen
Cotthembos (also known as Kottembos) is a forest complex in the East Flanders province of Belgium, spread across the territory of three municipalities: Sint-Lievens-Houtem, Zottegem (sub-municipality Oombergen), and Herzele (sub-municipality Hillegem). The area sits in the valleys of two small streams, the Klokfonteinbeek and the Cotthembeek, forming one of the larger continuous patches of greenery in the Flemish Ardennes, a region known for its rolling hills and patchwork of fields, hedgerows, and woodland. What does the landscape of Cotthembos look like? Rather than a single dense forest block, the area is a mosaic of larger and smaller wooded patches alternating with open fields and more enclosed sections of meadow bordered by pollard willows, a landscape feature typical of the region. This alternating pattern of forest, field, and meadow means a walk through Cotthembos offers constantly shifting scenery, from shaded tree lanes to open stretches with views of the surrounding hills. The dominant forest type is a mixed oak-hornbeam woodland, with an understory rich in forest shrubs and companion trees including maple and hazel alongside the oak and hornbeam. This layered structure, with a dense shrub layer beneath a mature canopy, is characteristic of mature deciduous lowland forests in this part of Europe and supports considerable species diversity. What wildlife lives in Cotthembos? The valley and its surrounding woods provide shelter for a varied range of animals. Mammals recorded in the area include the wood mouse and the coypu, a semi-aquatic species tied closely to the streams running through the site. Among tree-dwelling mammals, the European red squirrel is present, finding good foraging conditions in the mixed deciduous forest with its abundance of hazelnuts. The area is also significant for amphibians, hosting the alpine newt, a species that depends on clean, well-shaded water bodies for breeding. Birdlife is similarly rich: several woodpecker species make use of the mature timber for foraging and nesting cavities, and birds of prey hunt over the more open sections of the valley. Who manages the area and what protection status does it have? Cotthembos is a recognized nature area and nature reserve. Part of it is managed by the Flemish government's Agency for Nature and Forest (Agentschap voor Natuur en Bos) under the name "Valley of the Cotthembeek" (Vallei van de Cotthembeek). This status means the site benefits from planned habitat management aimed at preserving the biodiversity of the valley, including the mix of forest, meadow, and watercourses that supports its range of species. Is Cotthembos suitable for hiking or cycling? The area lies within the Flemish Ardennes, a region popular with both Belgian residents and visitors for its hilly terrain and dense network of trails. Its position across the borders of three municipalities, Sint-Lievens-Houtem, Zottegem, and Herzele, means the forest can be approached from several directions, making it a convenient starting point for walks that combine woodland with views over the open, agricultural surroundings typical of this part of East Flanders. Frequently asked questions Where exactly is Cotthembos located? On the border of three municipalities, Sint-Lievens-Houtem, Zottegem (Oombergen), and Herzele (Hillegem), in the East Flanders province of Belgium. What type of forest dominates Cotthembos? A mixed oak-hornbeam forest with a rich understory of forest shrubs, maple, and hazel. What animals live in Cotthembos? Species recorded include the wood mouse, coypu, European red squirrel, alpine newt, and several species of woodpeckers and birds of prey. Is Cotthembos a protected area? Yes, it is a recognized nature area and reserve, partly managed by the Flemish Agency for Nature and Forest under the name Valley of the Cotthembeek.

Wachtspaarbekken Bettelhovebeek
Strijpen
Wachtspaarbekken Bettelhovebeek is a small retention basin and marshland area in Strijpen, a village that forms part of the city of Zottegem in East Flanders, Belgium. Covering roughly one hectare, it sits in the valley of the Bettelhovebeek stream, right on the border between Strijpen and neighboring Velzeke. How did this place come to be? The Bettelhovebeek stream rises near the Bijloke area close to Grotenberge, then winds its way through Zottegem — passing Villa Cantaert, running between Egmontpark and Beislovenpark, and continuing alongside Egmontkasteel castle and the Leirenshof estate before reaching Strijpen. It was here, after the upper course of the stream was canalized, that a retention basin (wachtbekken) was built in 1982 to reduce the flood risk at the point where the Bettelhovebeek meets other watercourses. Over time, sediment carried by the water settled inside the basin, and a marsh gradually formed — the wetland that now defines this small natural area. Why is it worth a visit? Although the Wachtspaarbekken Bettelhovebeek is essentially an engineered structure with a practical purpose — protecting lower-lying land from flooding — it has quietly acquired a second identity as a modest nature reserve. Its marshy, waterlogged environment attracts wetland and water birds, making it an appealing stop for a short walk for anyone interested in nature while visiting the Zottegem area. It is a good illustration of how water-management infrastructure can, over the decades, evolve into a valuable habitat for local wildlife. What species can be found here? The marsh surrounding the basin is home to species such as the common kingfisher, the grey heron, the reed bunting (a small passerine tied to reedbeds), the mallard, and the common coot. The presence of these birds points to a mature, well-established wetland ecosystem that, despite its modest size, functions as a local refuge for water-associated birdlife. Birdwatchers will find early morning or evening the best time to visit, when animal activity tends to peak. How to get there and what to expect Wachtspaarbekken Bettelhovebeek is located in Strijpen, one of the smaller villages administratively part of Zottegem. Given its limited size and marshy character, the site is best approached as a short, quiet walk rather than a full day trip — there is no extensive tourist infrastructure here, just an intimate encounter with nature along the stream valley. Bringing binoculars is a good idea for anyone hoping to spot the local waterfowl. Frequently asked questions What is a wachtbekken (retention basin)? It is an artificial water basin designed to temporarily hold excess water during heavy rainfall or snowmelt, preventing flooding further downstream along the watercourse. When was the basin at Bettelhovebeek built? The retention basin was constructed in 1982, after the upper section of the Bettelhovebeek stream was canalized. What birds can be seen at this site? Species recorded in the marsh include the kingfisher, grey heron, reed bunting, mallard, and common coot. Where exactly is this place located? The area lies in Strijpen, a village belonging to the city of Zottegem in East Flanders, right on the border with neighboring Velzeke.

Makegemse bossen
Schelderode
Makegemse bossen is a roughly 200-hectare forest complex in the Merelbeke-Melle area of East Flanders, Belgium, spreading across the villages of Schelderode, Melsen and Munte. The name comes from the old hamlet of Makegem, around which a patchwork of smaller woodlands gradually took shape, separated by farmland and meadows. What does the complex actually consist of? Despite the single collective name, Makegemse bossen is not one continuous forest but a group of separate wooded patches, each with its own name: Makegembos, Heilig-Geestgoed, Harentbeekbos, Bruinbos, Nerenbos, Makenbos, Luisdonkbos (also called Huisdonkbos) and Hogenbos. Each patch has a slightly different character, but all share a canopy dominated by mature beech mixed with ash, hornbeam, hazel, wild service tree and rowan. Why is the area protected? The forests form part of the Flemish Ecological Network and, at the European level, fall under the Natura 2000 designation as part of the larger "Forests of the southeastern sandy loam region" site. That status reflects the well-preserved, mixed deciduous stands and the rich forest-floor flora typical of old woodland in this part of Flanders. What can visitors see in spring? Spring is the best time to visit, when the forest floor fills with flowers characteristic of fertile deciduous woodland: wood anemone, cowslip, musk stork's-bill, wild hyacinth (bluebell), herb Paris and Solomon's seal. This seasonal carpet of blooms draws both nature lovers and photographers to the area. What wildlife lives here? Roe deer and squirrels move through the woods, while buzzards, honey buzzards and several woodpecker species can be spotted overhead. In the damper corners of the complex, salamanders find a natural breeding habitat among the old deciduous stands and their scattered pools of water. How can the area be explored? Makegemse bossen is a popular destination for walking and hiking. Several marked routes cross the area, measuring 4, 6, 7 and 8 kilometres, catering to different fitness levels — including a route considered suitable for families with children roughly aged 3 to 12. The paths alternate between the interior of the individual forest patches and the open farmland between them, giving walkers a changing view of dense old woodland next to the region's typical agricultural landscape. Frequently asked questions Where exactly is Makegemse bossen located? The complex lies in the Merelbeke-Melle municipality in East Flanders, covering areas around Schelderode, Melsen and Munte. Is it suitable for a family walk? Yes, among the marked trails there is a 4 km route considered suitable even for young children. When is the best time to visit? Spring, when the forest floor flowers are at their peak, including carpets of wood anemone and wild hyacinth. Is the area under nature protection? Yes, it is part of the Flemish Ecological Network and the EU's Natura 2000 network.

Roche aux Corneilles
Bomal
Roche aux Corneilles is a limestone crag rising about 35 meters above the Ourthe river valley, right next to the village of Bomal, in Belgium's Luxembourg province. Sometimes referred to as Roche Hiernaux, it is one of the landmark rock formations of the Famenne-Ardenne region, where steep stone walls emerge straight out of the surrounding forest. What is this rock actually made of? Roche aux Corneilles is built from limestone, part of the geological belt known as the Calestienne that runs through the whole Famenne-Ardenne area. These limestone formations, shaped by water erosion over millions of years, are responsible for the steep rock faces that now tower above the Ourthe riverbed. The site has been recognized as one of the key geosites of the Famenne-Ardenne UNESCO Global Geopark, valued for its geological and scenic significance. What's hidden inside the rock? The rock mass contains four small cavities, one of which runs all the way through it. This passage is used as a training ground by cavers affiliated with the Belgian speleology union. For casual visitors, these cavities are mostly a curiosity visible from outside, and one of the features that sets Roche aux Corneilles apart from other rock faces in the area. Why do climbers keep coming back? The crag has been popular with climbers for decades, with the first routes established here back in the 1950s. Today it offers several dozen climbing routes of varying difficulty, from beginner-friendly lines to demanding ones, which is why the site draws both newcomers and experienced climbers looking for a challenge on solid limestone. How do you get there? Access is via the road from Bomal towards Aywaille, roughly 2.5 km from Bomal's main junction. Cars can be left at a hairpin bend near the ruins of Logne castle-fortress, from where a steep path descends alongside the rock toward the Ourthe. Even from the parking spot, the view over the river valley and surrounding hills gives a good preview of what's below. Is the site open year-round? No. To protect nesting birds, access to Roche aux Corneilles is restricted — the site is open from July 1st to January 31st, and closed from February through the end of June during the breeding season. This restriction comes from an environmental permit protecting the local birdlife nesting in the rock's crevices. What else is worth knowing before a visit? Beyond climbing and caving, the area around Roche aux Corneilles is popular with hikers — trails around the rock and along the Ourthe valley make for a pleasant walk with views over the river and nearby hills. The proximity of the ruined Logne castle makes it easy to combine a visit here with other historical sights in the region. Frequently asked questions Do you need a permit to climb here? The main condition is respecting the access period (July–January), which exists to protect birds nesting on the rock. Can the cavities inside the rock be visited on your own? The passage that runs through the rock is used by cavers for organized training sessions, not as a self-guided tourist route. Is there parking nearby? Yes, there is a parking spot at the bend on the road between Bomal and Aywaille, close to the ruins of Logne castle.

Teufelstein
Straelen
Teufelstein is a large boulder resting along Jülicher Straße, between the districts of Herongen and Hinsbeck within the town of Straelen in North Rhine-Westphalia, right next to the Blaue Lagune lake. The stone stands along the route of an ancient Roman road that once connected Xanten and Cologne, placing it at a crossroads of several historical eras along the Lower Rhine. What is the Teufelstein made of? The boulder consists of brown coal sandstone (Braunkohlensandstein), a rock originally formed in the Middle Rhine region. For a long time, it was assumed to be a glacial erratic carried to the area by the Scandinavian ice sheet during the last ice age. That theory was disproved by Professor Albert Steeger, who on November 8, 1954, during excavation work at the site, demonstrated that the rock had instead been transported to the Lower Rhine plain by the inland ice of the ancient Rhine (Urrhein), not from the north. The stone measures roughly 2.00 by 1.35 by 0.35 meters, a size considered remarkable for Lower Rhine conditions. What historical traces surround the stone? During the 1954 excavation, fragments of glass dating to the Biedermeier period—roughly the first half of the 19th century—were found beneath the boulder. This discovery suggests the stone once served as a boundary marker between the villages of Wankum and Herongen. That is not the only historical thread tied to this spot: a Roman waystation once operated nearby, active from the 1st to the 4th century AD. Pottery fragments, roof tiles, coins, and oil lamps stamped with legion markings found in the surrounding area attest to this Roman presence. What legend is connected to the Teufelstein? Local folklore tells of a farmer named Speith who made a wager with the Devil over who could throw farther. The Devil hurled the massive stone with great force, but the cunning farmer, instead of throwing a stone of his own, released a bird that flew far beyond where any stone could land. Through this trick, Speith won the bet, saving his soul and pocketing a purse of gold in the bargain. To this day, distinctive indentations remain visible on the stone's surface—said, according to the legend, to be the imprints of the furious Devil's fingers. How is the site protected today? The Teufelstein is protected as a natural monument and lies within the Heronger Buschberge nature reserve. Because of its ecological and historical significance, vehicle traffic along the adjacent stretch of Jülicher Straße is restricted, helping to preserve both the stone itself and the surrounding landscape. Frequently asked questions Where exactly is the Teufelstein located? The stone lies along Jülicher Straße, between the districts of Herongen and Hinsbeck in the town of Straelen, near the Blaue Lagune lake. Is the Teufelstein an ice-age glacial erratic? Not in the traditional sense. While it was once believed to be an erratic carried by the Scandinavian ice sheet, research from 1954 showed it is brown coal sandstone transported from the Middle Rhine region by the ancient Rhine's inland ice. Where does the stone's name come from? The name refers to a local legend about farmer Speith's wager with the Devil, whose supposed fingerprints are said to remain visible on the boulder's surface. Are there Roman remains near the stone? Yes. Nearby excavations uncovered the remains of a Roman waystation active from the 1st to 4th centuries AD, including pottery, roof tiles, coins, and oil lamps bearing legion stamps. Is the site legally protected? Yes, the Teufelstein holds natural monument status and sits within the Heronger Buschberge nature reserve, where vehicle traffic restrictions apply.

Rochers de Marche-les-Dames
Namur
Rochers de Marche-les-Dames is a chain of limestone cliffs stretching along the left bank of the Meuse River, just outside Namur, Belgium, toward the village of Marche-les-Dames. The rock formations run for roughly 2.3 kilometers along the river and rank among the most recognizable cliff landscapes of the Meuse valley in Wallonia. What makes this site geologically and visually notable? The massif is made up of 23 distinct rock outcrops, ranging from 20 to 80 meters in height. Because of their scale and condition, the cliffs are listed as part of the Major Heritage of Wallonia (Patrimoine majeur de Wallonie), a designation that recognizes their landscape and natural value within the region. Why is this location important for climbers? More than 400 climbing routes have been established on the rocks, most of them athletic in style, demanding strength and technical precision rather than long endurance pitches. This has made Marche-les-Dames the second most important rock-climbing destination in Belgium, ranking just behind the renowned Freÿr cliffs. For decades the site has drawn climbers from across Belgium and neighboring countries, and it remains a reference point for the Club Alpin Belge, which organizes outdoor climbing activities here. What historical event is tied to these cliffs? The best-known episode connected to the site is the death of King Albert I of Belgium. On February 17, 1934, the king, an enthusiastic mountaineer and climber, died in a solo climbing accident on one of the rocks in the massif. The event shocked the country and remains remembered as one of the most unusual deaths of a European head of state in the 20th century. A memorial stands at the base of the cliff where the accident occurred, drawing both climbers and visitors interested in Belgian history. Is the entire rock massif open to visitors? Not entirely. Part of the site lies within a military camp used by Belgian army para-commandos, so access to some sections of the cliffs is restricted or requires military clearance. Visitors and climbers are advised to check current signage and access rules before approaching the areas closest to the camp. What else can visitors do in the area besides climbing? The Meuse valley at this point is a popular destination for walking and hiking, with riverside paths offering views of the steep cliff faces and the river itself. The nearby Notre-Dame du Vivier abbey adds a heritage dimension to a visit, allowing travelers to combine the natural landscape with a piece of the region's monastic history. Frequently asked questions Can beginners climb here? The terrain is demanding — most routes are athletic and better suited to experienced climbers, ideally accompanied by an alpine club or a qualified instructor. Is access to the site free? Reaching the cliffs and the walking paths is free, though part of the area is subject to restrictions due to its proximity to military grounds. How do you get to Rochers de Marche-les-Dames? The site sits directly along the Meuse, a few kilometers from central Namur, next to the road and railway line that follow the river valley toward the village of Marche-les-Dames.

Roche Trouée
Nismes
Roche Trouée is a limestone rock formation in Nismes, part of the municipality of Viroinval, in the Calestienne geological region of Namur province, Belgium. Its name — literally "pierced rock" in French — comes from the striking hole that passes right through the outcrop. It ranks among the most recognizable landmarks of the Viroin valley and sits along the network of trails that also lead to the nearby Fondry des Chiens. How did this rock formation form? The outcrop is built from Devonian-era limestone shaped over millions of years by water. Inside it, a dense network of caves, passages and hollow chambers developed — a classic result of the karst processes for which the Calestienne region is known throughout Belgium. The rock's signature through-hole is the product of that same long chemical and mechanical erosion of limestone. What do the caves at Roche Trouée hold? The caves carry real archaeological weight. Objects recovered from them date back to the Upper Palaeolithic, between 12,000 and 45,000 years ago, left by people who sheltered here from harsh conditions. Slightly further south, a Neolithic collective grave was uncovered, roughly 4,000 years old. At the western end of the site, the remains of a Roman dwelling were found, occupied between 230 and 400 AD. Together these finds show that the area around Roche Trouée was inhabited, on and off, across thousands of years. Why does this site matter for nature? Today the caves serve as a winter hibernation site for bats, making them an important part of the local ecosystem. Roche Trouée is classified as a site of significant biological interest, alongside the neighbouring Fondry des Chiens, and falls within the state nature reserve of the Viroin valley. The limestone grasslands surrounding the rock support rare plant and animal species adapted to the dry, sun-exposed conditions typical of calcareous soil. What should visitors know before going? Roche Trouée lies along popular walking trails starting from Nismes, often combined into a single outing with the Fondry des Chiens — a huge karst sinkhole reaching depths of up to 20 metres, a geological feature found in Belgium only in the Viroin region. The site is protected, so visits should stick to the marked paths on the surface rather than entering the caves themselves, which shelter protected bat species. Frequently asked questions Where exactly is Roche Trouée located? In Nismes, part of the municipality of Viroinval, Namur province, Wallonia, within the Calestienne geological region. Where does the name come from? From the distinctive hole carved straight through the rock by water and karst processes. Can visitors enter the caves? The caves are a winter refuge for bats and lie within a protected area, so access is limited to the surface trails around the site. What else is worth seeing nearby? The neighbouring Fondry des Chiens, a deep karst sinkhole recognised as a natural monument, reachable via the same trail network from Nismes.

Rocher Bayard
Dinant
Rocher Bayard is a distinctive rock formation rising above the bank of the Meuse river in Dinant, in the Belgian region of Wallonia. It sits in the province of Namur, within the Ardennes, at coordinates 50.244616, 4.921156 — right along the stretch of the valley where the river cuts between steep, limestone-lined slopes. Where exactly is Rocher Bayard located? The rock formation is part of the landscape of Dinant, a city and municipality straddling both banks of the Meuse. The town itself lies about 90 kilometres southeast of Brussels, 30 kilometres southeast of Charleroi, and 30 kilometres south of the city of Namur. The border with France is only about 20 kilometres to the south, meaning Dinant sits at the edge of the Belgian Ardennes, close to where the terrain gradually gives way to the more mountainous borderlands on the French side. The Ardennes, where Rocher Bayard is found, are known for densely forested hills and river valleys cut deep into the bedrock. The Meuse valley running through Dinant is one of the most recognisable stretches of this range — the river carves narrow passages through rocky massifs here, leaving behind steep rock faces and tall outcrops. Rocher Bayard is one such feature of this rocky landscape, visible directly from the riverbed and from the roads that follow its banks. Why is this rock a fixture of Dinant's landscape? The shape of the valley at this point — steep limestone walls hemming in the Meuse's course — means that rock formations of this kind are a natural part of the skyline around Dinant. Sitting right beside the river, Rocher Bayard functions as one of the landmarks along this section of the valley, visible to anyone travelling either by water or along the roads that run beside it. Frequently asked questions In which country and region is Rocher Bayard located? In Belgium, in the region of Wallonia, in the province of Namur. Which river does this rock formation stand beside? The Meuse, in the city and municipality of Dinant. How far is Dinant from major cities? Brussels is about 90 km away, Charleroi about 30 km, and Namur about 30 km. How close is the French border? The border with France lies roughly 20 km south of Dinant. What geographic region is this located in? The Belgian Ardennes, an area of hilly, upland terrain marked by river valleys and rocky slopes.

Le Hérou
Houffalize
Le Hérou is one of the most striking viewpoints in the Belgian Ardennes — a rocky ridge rising above a bend of the Ourthe river, near the village of Nadrin, in the municipality of Houffalize. The rock mass stretches close to a kilometer in length, reaching about 80 meters in width at its base and more than 80 meters in height. The site lies within the Deux Ourthes Nature Park (Parc naturel des Deux Ourthes), which spans six municipalities: Bertogne, Gouvy, Houffalize, La Roche-en-Ardenne, Sainte-Ode and Tenneville. Where does the name come from? Local legend claims that a herald once proclaimed sentences handed down by the High Court of Nadrin from the top of this rock. The story is often cited as the origin of the site's name, though like many folk tales its historical accuracy is difficult to confirm. What can you see from the top? The panorama from the Hérou ridge is one of the most distinctive in the region — the Ourthe river winds through a deep gorge, wrapping around the rocky spur on almost every side and creating a scene some compare to landscapes in the French Alps. The rock was once entirely stripped of vegetation, which further emphasized its raw, monumental silhouette against the green slopes of the valley. The site has been a protected, classified rock ridge since 1937 and carries a two-star rating in the Michelin Green Guide — a rare distinction for this part of the Ardennes. How do you reach the top? The most popular way to explore the site is a roughly 6-kilometer walking loop known as the "Promenade du Hérou," starting in Nadrin, running along the ridge and back to the starting point. The descent from the rock can be steep and occasionally tricky underfoot, and is not recommended for young children — but the reward, a sweeping view over the river's meanders, makes the climb worthwhile. In Nadrin itself, right above Le Hérou, stands the Six Ourthes viewing tower (Tour d'Orientation des Six Ourthes), offering a 360-degree panorama over the surrounding hills and valleys — a natural complement to a walk along the rocky ridge. Frequently asked questions Is climbing Le Hérou difficult? The approach trail is moderate, but the descent along the ridge can be steep and slippery after rain, so proper footwear is recommended. How long does a visit take? The full walking loop around Le Hérou typically takes 1.5–2 hours at a relaxed pace, depending on how many stops you make for photos. Is it worth combining with the Six Ourthes tower? Yes — both viewpoints are close together in Nadrin and together give a fuller picture of the Ourthe valley landscape. Is the site suitable for families with children? Because of steep sections and a lack of railings in places, the trail requires caution and is not recommended for very young children.

Le Faix du Diable
Wanne
Le Faix du Diable is a massive sandstone boulder resting on top of a hill near the village of Wanne, deep in the Ardennes, in the province of Liège. The name literally means "the devil's burden," referring to the legend of a rock the devil himself is said to have once carried on his back. Where exactly is the rock located? The boulder sits roughly 800 meters south of Wanne, along the road leading to the old hamlet of Logbiermé. The spot lies on the former border between Belgium and Prussia, which gives the walk an extra layer of history — following the route means retracing an old territorial boundary through the forest. Where does the name "devil's burden" come from? According to local legend, the devil, furious about the construction of the abbey at Stavelot by Saint Remaclus, decided to crush the young monastic community with an enormous rock he carried on his own back. Saint Remaclus, anticipating the threat, sent a messenger disguised as a monk to intercept him, carrying a sack full of worn-out shoes. When the devil asked how much farther it was to Stavelot, the messenger showed him the ruined footwear, claiming he had worn through that many pairs simply traveling from there. Convinced the abbey lay much farther away than he had thought, the devil lost heart, dropped the boulder on the spot, and turned back. The stone, so the story goes, has remained there ever since. What makes the rock itself interesting? The Faix du Diable is not just a random boulder left behind — it's a witness to hundreds of millions of years of geological history. It forms part of a larger sandstone rock mass shaped by erosion and the tectonic movements typical of the Ardennes highlands. That geological backstory draws not only fans of local folklore but also visitors interested in the region's rock formations. How can visitors reach and explore it? From the picturesque hamlet of Wanne, a walking loop follows the old Belgian-Prussian border, passes through the old hamlet of Logbiermé, and arrives at the rock itself. It's a peaceful hiking route through classic Ardennes scenery — forested hills and views typical of this part of Liège province. The area is also known among road cyclists: the climb from Grand-Halleux runs about 3.5 km with an average gradient of 6.4%, and the hill can be tackled from several different sides, with the Spineux approach being the most popular. Who is this destination for? Le Faix du Diable blends folklore with nature, making it a good fit for anyone looking for a quiet walk with a story attached, while also appealing to road cyclists training on Ardennes climbs. It's a worthwhile stop for travelers exploring the lesser-known, quieter corners of Liège province, away from the busier tourist trails. Frequently asked questions Is the walk to the rock difficult? The route from Wanne is a gentle hike over rolling hills, with no extreme climbs — accessible to most walkers. Is there any historical basis for the devil legend? No, it's a traditional folk legend tied to the Stavelot abbey and Saint Remaclus, passed down orally in the region for generations. Is the site suitable for cyclists? Yes, the hill is a known road-cycling climb near Grand-Halleux, reachable via several different routes.

Peetje en Meetje
Ruien
Peetje en Meetje is a small but curious arrangement of stones tucked away on the northwestern slope of the Kluisberg, inside the Kluisbos forest near Ruien, part of the municipality of Kluisbergen in Belgium's East Flanders. The name comes from the local dialect and loosely translates as "godfather and godmother" — a nickname that has puzzled hikers stumbling upon the stones during forest walks for generations. What exactly is hidden in the forest? The site consists of two large blocks of iron sandstone, positioned side by side in a way that resembles a megalithic structure. Their bulky, irregular shape has long invited speculation about who placed them there and why. The real story, though, turns out to be far more down-to-earth than the stones' mysterious appearance suggests. Where do the legends about a sacrificial altar come from? Several tales circulate about Peetje en Meetje, the most colorful being that of a Celtic stone altar once used for offerings. Another version claims the stones form a genuine dolmen — a megalithic burial chamber thousands of years old. Such legends are hardly unique in Europe: unexplained stone formations tend to attract folklore, especially when solid historical documentation is scarce. What is the real history behind the site? In fact, the arrangement is what's known as a folly — a decorative structure built purely for visual and imaginative effect, without any practical function. Follies like this were popular additions to nineteenth-century parks and forests frequented by wealthy visitors and day-trippers seeking leisure in nature. Peetje en Meetje dates back to exactly that period, the late nineteenth century, when the Kluisberg and its surrounding woods began drawing growing numbers of tourists. To make the walk more intriguing, the distinctive boulders were arranged in the forest, evoking associations with prehistoric megalithic monuments among visitors. The story doesn't end in the nineteenth century, however. In the 1980s, an additional stone was placed on top of the existing arrangement, making the whole structure look even more like a classic dolmen — complete with a capstone resting on two upright boulders. That later addition is why Peetje en Meetje is today often described as a "pseudo-dolmen": it looks like a prehistoric monument, even though its origins go back only a few generations rather than several millennia. Why is it worth a visit? Even though Peetje en Meetje isn't an authentic relic of prehistory, the site has a charm of its own. It combines the scenic appeal of the Kluisbos forest with a touch of mystery and a good dose of local folklore. It makes for a rewarding short stop during a longer walk through the hills of the Kluisberg — a spot to pause, read up on the legends, and reflect on how easily nature and human imagination can combine to create a myth. Frequently asked questions Is Peetje en Meetje a real dolmen? No. It is a nineteenth-century decorative folly, to which an extra stone was added in the 1980s to make it look more like a dolmen. Where exactly is it located? On the northwestern slope of the Kluisberg, inside the Kluisbos forest, near Ruien, in the municipality of Kluisbergen. Where does the name come from? It comes from the local dialect and refers to a godfather and godmother — a nickname given to the stones by local residents. Is it the only attraction in Kluisbos? No — the forest also offers other walking trails and viewpoints across the hills of the Kluisberg, popular with visitors to the region.

Zyklopensteine
Raeren
Zyklopensteine is an unusual natural monument tucked into the southern edge of the Aachen Forest, on the territory of the Belgian municipality of Raeren, right along the border with Germany. The site consists of roughly fifty rock blocks scattered across about one hectare of woodland, split by an old boundary ditch known as the Aachen land ditch, which separates the Belgian and German portions of the formation. Where do these rocks come from? The Zyklopensteine blocks formed from a loose sedimentary material called Aachen sand, deposited during the Upper Cretaceous — specifically the Santonian stage, around 84 to 85 million years ago, when a shallow sea covered the region. Over time, silica-rich groundwater cemented parts of this sand through a process called silicification, binding the loose grains into hard, solid masses. As the surrounding softer sediment gradually eroded away, these hardened, silicified blocks were left standing exposed, scattered across the forest floor much as they appear today. How big are the blocks and what do they look like? The individual blocks vary considerably in size, from modest fragments to substantial boulders. Their surfaces are often irregular, marked by hollows and protrusions that in places resemble facial features. It is precisely these strange, eye-like indentations that gave the site its name, linking the rocks in local memory to the one-eyed giants of Greek mythology, the Cyclopes. Why are they called Zyklopensteine? The name refers directly to the Cyclopes, the mythical one-eyed giants. Local tradition long recognized in the irregular, hollowed-out shapes of the boulders a resemblance to the giants' single eye sockets, and this association stuck, becoming the accepted name for the entire rock formation and a recurring theme in stories told about the site. Where exactly is the site located? The natural monument lies just south of the city of Aachen, mostly on Belgian soil within the municipality of Raeren, though a portion of the blocks extends onto German territory. The old administrative boundary ditch runs directly through the site, making it a notable example of a place where a geological curiosity and a historical border line intersect within a small stretch of forest. Is it a good spot for a walk? Zyklopensteine sits in a quiet, wooded setting and is accessible to visitors as a walking destination or short hike. Because the boulders are spread across roughly a hectare, exploring the site means moving slowly between the trees, discovering one rock formation after another away from the busier attractions of the surrounding region. Frequently asked questions Is Zyklopensteine an archaeological site? No — it is a geological formation and protected natural monument, not something built by human hands. The blocks were shaped by natural geological processes tens of millions of years ago. Can all the rocks be seen from one spot? No, the boulders are scattered across about a hectare of forest, so seeing them means walking a short distance between the individual blocks. Is the site in Belgium or Germany? Most of it lies in Belgium, within the municipality of Raeren, but part of the formation extends across the old border line onto German territory. Where does the name Zyklopensteine come from? From the Cyclopes of Greek mythology — the irregular, hollowed shapes of some blocks reminded local people of the single eye sockets of these mythical giants.

Grottes de la Chantoire
Dison
Grottes de la Chantoire is a small karst cave complex located in Andrimont, a former municipality now part of Dison, in the province of Liège, Wallonia. The site sits above the river Vesdre, on steep cliffs between Surdents and Renoupré, and has been protected since 1945 for its ecological value. The whole domain covers roughly 8 hectares and remains private property, meaning access to the interior of the caves is not freely open to visitors without the owner's permission. What is inside the caves? The main cave opens on the right bank of the Vesdre and develops into a long corridor leading to a small inner chamber. Deep inside, several rock chimneys, partly filled with sediment, mark centuries of water erosion carving through the limestone. Besides the main grotto, popularly known as Trou des Sottais, the domain also contains a second cave called Trou des Deux Copines. What kind of wildlife lives here? The caves shelter troglophile invertebrates, meaning species adapted to cave conditions but not strictly dependent on them, as well as several species of bats. This makes the site an important refuge for protected local fauna, and it explains part of the restrictions on entering the interior. What is the history behind the site? The history of Chantoire goes back to the Middle Ages. According to local tradition, monks connected to a crusading order settled here in 1225 and established a sanctuary on the site. The ruins of an old chapel dedicated to Saint Anne can still be found within the domain today. Historical records mention restoration work on the chapel in 1437, the same year in which the prince-bishop of Liège is said to have authorized the founding of a hermitage at this location. The combination of natural caves, river cliffs, and the remains of a religious building gives Chantoire both ecological and archaeological-historical significance. Are there any legends associated with the place? The Dison area and the Vesdre valley are rich in local folklore tied to "nutons," small mythical figures from Walloon folk tradition often associated with caves and rocky shelters. One such story, the legend of the Nuton Tonké, is linked to this region and has been passed down through oral tradition as part of Andrimont's cultural identity. Can visitors explore the caves on their own? Because the site is private property and has been protected since 1945, entry into the caves themselves is not freely available — this is not a site prepared for mass tourism like commercial show caves. Visitors can, however, appreciate the landscape of the Vesdre valley, its steep slopes, and the surrounding vegetation from publicly accessible paths around Andrimont. Frequently asked questions Where exactly are the Grottes de la Chantoire located? In Andrimont, part of the municipality of Dison, in the province of Liège, along the river Vesdre, between Surdents and Renoupré. Are the caves open to visitors? The site is private and has been protected since 1945, so entering the caves themselves is not freely possible without the owner's permission. What animals live in the caves? Troglophile invertebrates and several species of bats, making the site significant for local protected fauna. What is the history of the site? It dates back to the 13th century — tradition holds that monks of a crusading order settled here in 1225, and records from 1437 mention chapel restoration work and permission to found a hermitage.

Chantoir de Béron Ry
Sprimont
Chantoir de Béron Ry is one of the characteristic karst swallow holes in the Vallon des Chantoirs, a valley stretching across the municipalities of Sprimont and Aywaille in the province of Liège, in Belgium's Walloon Region. It sits close to the small hamlet of Hotchamps, part of the municipality of Sprimont. What exactly is a chantoir? The word "chantoir" comes from the Walloon dialect and describes a spot where a surface stream suddenly disappears underground, entering a karst system. The name refers to the sound made by water rushing into the rock — a noise likened to singing ("chant"), especially audible after heavy rainfall when flow increases. Chantoirs are, in essence, natural swallow holes typical of limestone terrain, where surface water meets soluble rock and exploits cracks and fissures to sink into the massif. Where it lies and its geological setting Chantoir de Béron Ry is located within the Vallon des Chantoirs, a valley carved into Middle Devonian limestone. It is precisely this type of rock, susceptible to dissolution by water, that allowed an extensive karst system to develop in the area. Around seventy chantoirs have been catalogued across the whole valley, making it one of the most densely packed pockets of karst activity in this part of the Ardennes. The site's approximate coordinates are 50.4999°N, 5.7067°E, with the hamlet of Hotchamps as the nearest reference point. How the wider system it belongs to works Water that disappears at Chantoir de Béron Ry does not end its journey there — this is only the start of an underground route. Streams sinking into the various chantoirs of the valley join a common underground collector, which, after travelling through the limestone massif, resurfaces at the Remouchamps caves, one of the region's best-known tourist attractions. This underground river carries its own name, the Rubicon, a detail that reflects how central the whole karst system has become to the local geography and folklore. Is Chantoir de Béron Ry the only feature of its kind nearby? No. The Vallon des Chantoirs contains many similar swallow holes, several of which have their own names and some degree of recognition among visitors to the region — among them the Trou-le-Coq chantoir, the Grandchamps chantoir, the Hotchamps chantoir, the Pussin chantoir, and the Rouge-Thier chantoir (also known as Trou du Moulin). One of them, the Sécheval chantoir, has been listed as Exceptional Heritage of Wallonia. Chantoir de Béron Ry belongs to this same family of features, forming together with the others a coherent, if surface-scattered, drainage system for the valley. Frequently asked questions What does the word "chantoir" mean? It is a Walloon term for a place where a stream disappears underground into a karst system — the name refers to the sound made by the sinking water. Where exactly is Chantoir de Béron Ry located? In the Vallon des Chantoirs, near the hamlet of Hotchamps, within the municipality of Sprimont, province of Liège. Where does the water that vanishes here end up? It joins underground with water from other chantoirs in the area and resurfaces at the Remouchamps caves as an underground river known as the Rubicon. Are there other similar features nearby? Yes, around seventy chantoirs have been catalogued in the Vallon des Chantoirs, including several other named ones. What kind of rock forms this landscape? Middle Devonian limestone, which is soluble in water and allowed the karst system to develop over time.

Chantoir de Chefosse
Sougné-Remouchamps
Chantoir de Chefosse is a natural karst feature located near the village of Deigné, in the municipality of Aywaille, Liège Province, Belgium. It belongs to a category of local landforms known as "chantoirs" — points where a permanent or seasonal watercourse disappears underground and continues its journey through a hidden subterranean channel. The site lies within the so-called Vallon des Chantoirs, a valley stretching from north to south between Louveigné (municipality of Sprimont) and Remouchamps (municipality of Aywaille). What exactly is a chantoir? The term "chantoir" is regional geological vocabulary used in the Ardennes and the limestone areas of eastern Belgium. It describes a spot where flowing water sinks into a clearly marked depression in the ground and vanishes into an underground karst system, resurfacing elsewhere or feeding a hidden network of channels invisible from the surface. This phenomenon is typical of limestone landscapes, where water gradually dissolves the rock, carving out caves, conduits and sinkholes over long periods of time. Location and regional context Chantoir de Chefosse sits close to the village of Deigné, an area well known for a dense concentration of similar landforms. Within the Vallon des Chantoirs, roughly 70 such features have been recorded, making this stretch of countryside one of the richest karst landscapes in Belgium. The abundance of chantoirs and dolines around Deigné has long attracted the attention of geologists as well as local residents, for whom the pockmarked terrain of sinkholes and depressions is a familiar and defining part of the surroundings. The site's approximate coordinates are 50.508015°N, 5.731913°E, placing it in the scenic, hilly countryside of the Amblève valley, close to the well-known tourist area of Sougné-Remouchamps, home to the famous Remouchamps cave system. Current condition Available information indicates that Chantoir de Chefosse has gradually filled in over time — a natural stage in the life cycle of many karst sinkholes, as sediment, debris and plant matter accumulate and close off the original opening where water once disappeared. Even so, the site remains a point of interest for the region's natural heritage and is listed among the landscape features documented by tourism bodies covering the Ourthe-Vesdre-Amblève area. Landscape and natural significance Chantoirs, including Chantoir de Chefosse, form an important part of the local ecosystem and the region's geological story. Together they shape a distinctive, uneven landscape where depressions in the ground — sometimes overgrown with vegetation, sometimes exposing bare rock — bear witness to karst processes that have been at work beneath the surface for thousands of years. For visitors interested in geology and natural landscapes, the area around Deigné and the wider Vallon des Chantoirs offers a chance to observe these formations firsthand, within easy reach of the better-known attractions of the Amblève valley. Frequently asked questions What is a chantoir? A chantoir is the regional term for a swallow hole — a point where a watercourse disappears underground and continues along a hidden channel, a feature typical of the karst terrain of eastern Belgium. Where is Chantoir de Chefosse located? Near the village of Deigné, in the municipality of Aywaille, Liège Province, within the valley known as the Vallon des Chantoirs. Can Chantoir de Chefosse be visited? The feature has gradually filled in over time, but it remains a point of interest along routes exploring the region's natural heritage. How many similar features exist in the area? Around 70 chantoirs have been recorded within the Vallon des Chantoirs, making it one of the richest concentrations of this karst landform in Belgium.

Ramioul (Grotte de) à Flémalle
Flémalle
Ramioul Cave is a natural cavern and archaeological site located in Flémalle, in the province of Liège, in the Walloon region of Belgium. Set on the banks of the Meuse river and surrounded by a Natura 2000 nature reserve, it forms the core of what is known today as the Préhistomuseum (formerly the Préhistosite de Ramioul). How was the cave discovered? The cave was discovered in 1911 by members of the association "Les Chercheurs de la Wallonie" (The Searchers of Wallonia). Successive excavation campaigns uncovered occupation layers spanning an enormous stretch of time — from roughly 70,000 years ago, when Neanderthals associated with the Mousterian culture inhabited the area, through to the end of the Neolithic period around 2300 BC. Traces of the Aurignacian culture, linked to early Homo sapiens, were also found among the site's layers. Why is this site significant? Ramioul Cave is considered one of the most important archaeological and natural heritage sites in Wallonia. Some of the very first Neanderthal fossils ever identified were unearthed here, giving the site significance well beyond the regional level. The successive cultural layers, spanning tens of thousands of years, make it possible to trace how the human populations of the region changed over time — from the earliest hunter-gatherer groups to the farming communities of the late Stone Age. Today the cave itself sits within a protected area classified under the Natura 2000 network, meaning it carries ecological weight alongside its archaeological importance, sheltering local flora and fauna typical of the river valleys around Liège. What can visitors see on site? The Préhistomuseum that has grown around the cave invites visitors on a journey spanning half a million years of human history. A visit typically includes the cave itself, museum exhibitions dedicated to prehistoric life, temporary exhibits, and a reconstructed experimental prehistoric village where visitors can see recreated living conditions of past communities. The complex therefore combines the functions of a museum, an open-air heritage park, and a nature reserve in a single destination. This combination draws a broad range of visitors — archaeology and history enthusiasts, families looking for an educational outdoor outing, and nature lovers exploring the surrounding reserve along the Meuse. Frequently asked questions Where is Ramioul Cave located? In Flémalle, in the province of Liège, in the Walloon region of Belgium, along the Meuse river. When was the cave discovered? In 1911, by members of the association Les Chercheurs de la Wallonie. What archaeological findings are associated with it? Traces of occupation from about 70,000 years ago (Neanderthals, Mousterian culture) through the end of the Neolithic period (around 2300 BC), including remains of the Aurignacian culture. What can be visited there today? The cave itself, the Préhistomuseum exhibitions, a reconstructed prehistoric village, and the surrounding Natura 2000 protected area.

Trou des Nutons
Dinant
Trou des Nutons is one of the best-known caves in the Furfooz Nature Reserve, set along the Lesse river a few kilometres from Dinant. Its name comes from local folklore about the nutons — small, mischievous dwarf-like creatures said to possess supernatural skills, who according to legend would carry out little pieces of craftwork for villagers overnight in exchange for food. This fairy-tale origin gives the site an immediately intriguing character, though the cave's real significance lies in its geology and archaeology. What makes this cave geologically important? Trou des Nutons marks the spot where the Lesse river disappears underground, beginning a subterranean course through the limestone hills of Furfooz. The river resurfaces nearby at the Trou de la Loutre, and together the two openings form a natural hydrological system typical of the karst landscapes found throughout this part of the Ardennes. A small, near-vertical rock opening leads into the limestone hillside, where flowing water has carved out passages and chambers over thousands of years. What has been discovered inside the cave? The greatest significance of Trou des Nutons comes from its role as an archaeological site dating to the Magdalenian period, part of the Upper Palaeolithic. The cave was inhabited by humans as far back as roughly 14,000 years ago, making it one of the most important traces of prehistoric human presence in the Lesse valley. In 1866 the site was excavated by Belgian archaeologist Edouard Dupont, in one of the earliest systematic digs carried out in the region. The excavation uncovered the remains of seventeen individuals, a discovery that sparked lively scientific debate at the time about the physical characteristics of the area's prehistoric inhabitants. Dupont's findings at Furfooz contributed to the development of Belgian prehistoric archaeology and are still referenced in scholarly literature on the Palaeolithic in Western Europe. What should visitors know before going? Trou des Nutons lies within the Furfooz Nature Reserve, an area shaped by a scenic bend of the Lesse, limestone outcrops and a network of walking trails. The cave is open to visitors today as one of the stops along the trail that runs through the reserve, alongside the area's other caves. Visitors can look into the small rock opening and see the exact spot where the river vanishes underground, while standing in a place of real importance for understanding how people lived during the last Ice Age. Frequently asked questions Where does the name Trou des Nutons come from? It comes from the legendary nutons, nocturnal dwarf-like figures from regional folklore said to help villagers with small tasks in exchange for food. How long ago did people live in this cave? Traces of habitation date back to the Magdalenian period, around 14,000 years ago. Who carried out the archaeological research at Trou des Nutons? The 1866 excavation was led by Belgian archaeologist Edouard Dupont, who uncovered the remains of seventeen individuals. Can the cave be visited independently? Yes, it lies within the Furfooz Nature Reserve and is accessible along the park's marked walking trails.

Chantoir de Sècheval
Sougné-Remouchamps
Chantoir de Sècheval is a protected karst feature in Belgium's Liège province, tucked into the small hamlet of Sécheval, part of the municipality of Aywaille. It sits north of Remouchamps toward the village of Deigné, and south of Sécheval itself, right along the N666 national road connecting Louveigné and Remouchamps. It's a quiet stop for anyone drawn to the geological side of the Belgian Ardennes rather than just its scenic trails. What exactly is a chantoir? In Wallonia, a "chantoir" (also called a "perte," meaning "loss") is a natural opening in the ground where a surface stream disappears, feeding into an underground karst system. The name Sécheval itself translates to "dry valley," referring to the Vallon des Chantoirs, the valley where this hamlet sits — an apt description, since the stream simply vanishes above ground and continues its journey below. Where does the water come from, and where does it go? The Minières stream rises north of Hautregard and flows west through woodland for roughly three kilometers before sinking underground precisely at the Chantoir de Sécheval. Studies of this karst system revealed something remarkable: the waters of several streams merge underground into a shared collector that eventually resurfaces at the Remouchamps caves. This underground river even has its own name — the Rubicon. What lies beneath the surface? The galleries extending underground are subhorizontal and can be explored for approximately 300 meters, with a total elevation change of 21 meters. Because of its scientific value, the site holds the official status of a Cavity of Scientific Interest, underlining its importance not just as a landscape curiosity but as a genuinely useful site for hydrogeological research in the region. Why is it worth visiting? Chantoir de Sècheval is one of those spots in the Ardennes where science and landscape overlap. The opening where the stream disappears underground may look modest next to the region's more spectacular show caves, but its hydrological significance is considerable — this is where the underground journey begins for water that eventually surfaces at the famous Remouchamps caves, one of the area's most popular tourist attractions. The site appeals to visitors interested in karst geology, anyone tracing the region's hidden waterways, and travelers spending extended time around Aywaille and Remouchamps who want to understand the hidden water system running beneath their feet. Frequently asked questions Can you go inside the chantoir? Given its status as a protected area and the nature of a natural cave system, exploring it calls for real caution and is best done with local guides or as part of an organized speleological trip. How do you get to Chantoir de Sècheval? It sits along the N666 road between Louveigné and Remouchamps, close to the villages of Deigné and Sécheval, within the municipality of Aywaille. Is this the same place as the Remouchamps caves? No, though the two are connected underground — the water that disappears at Chantoir de Sècheval resurfaces at the Remouchamps caves, forming a single continuous karst system.

Goyet Caves
Mozet
The Goyet Caves form a series of connected caves cut into a limestone cliff rising about 15 meters above the river Samson, near the village of Mozet in the Gesves municipality, in Belgium's Namur province. The site ranks among the most significant archaeological localities in the region, preserving evidence of both Neanderthal and early modern human presence in Europe. What has been found in the caves? Excavations at Goyet have uncovered thousands of fossils and artifacts, all attributed to a single, long, and uninterrupted stratigraphic sequence. This sequence spans roughly 120,000 years, starting in the Middle Paleolithic and continuing to less than 5,000 years ago, in the late Neolithic. Few sites offer such a continuous record in one location, which is why Goyet plays an important role in tracing how different human groups occupied the region over tens of thousands of years. Who first studied the site? The first serious investigations at Goyet were carried out by geologist Edouard Dupont, who began probing excavations as early as 1867. His work, followed by more extensive later excavations, made it possible to identify a robust and well-preserved sequence of sediments. This foundational research helped establish Goyet as a key reference point for Paleolithic studies in Western Europe. Why is the site protected? Given its scientific importance, the Goyet Caves were added to the Belgian National Heritage register in 1976. This recognition reflects the site's value not only for local history but for the broader understanding of human settlement across Europe during the Stone Age. Where exactly are the caves located? Goyet lies in Namur province, within the Gesves municipality, close to the village of Mozet. The caves are carved into limestone typical of this part of Belgium, and their position above the river Samson — roughly 15 meters above the waterline — explains why the site offered natural shelter for so many millennia. Frequently asked questions Did Neanderthals live in the Goyet Caves? Yes, the site documents the presence of Neanderthals alongside early modern humans, within a single continuous sedimentary sequence dating back 120,000 years. Who conducted the first excavations there? Geologist Edouard Dupont, who began the first probing excavations in 1867. How far back does the site's history go? The stratigraphic sequence covers the period from the Middle Paleolithic (120,000 years ago) to the late Neolithic (less than 5,000 years ago). Where exactly are the Goyet Caves located? In Namur province, within the Gesves municipality, near the village of Mozet, in a limestone cliff above the river Samson. Is the site formally protected? Yes, it was added to the Belgian National Heritage register in 1976.

Chantoir d'Adzeux
Sprimont
Chantoir d'Adzeux is a natural sinkhole located at the small settlement of Adzeux, today part of the village of Louveigné within the municipality of Sprimont, in the Belgian province of Liège. It sits within the Vallon des Chantoirs, a valley stretching from Louveigné to Remouchamps (in the municipality of Aywaille) that is known for its unusually high concentration of this particular karst feature. What exactly is a chantoir? Chantoir is a term used in the Ardennes and Condroz regions of Belgium to describe a spot where a surface stream suddenly disappears, flowing into an underground network of channels carved through limestone rock. The phenomenon is a direct result of the erosion of carbonate rock: limestone, unlike crystalline rock, dissolves relatively easily under the action of mildly acidic rainwater, and over long periods this process carves out caves, conduits, and cavities beneath the surface. The name itself comes from the sound made by water rushing abruptly into the ground — a noise likened to "singing," which gave rise to this regional term. Where does the Banneway stream go? At Chantoir d'Adzeux, the stream that vanishes underground is the Banneway (also known as the Ru de Banneux). It flows into the sinkhole near the center of the former village of Adzeux, then continues its course beneath the surface. After traveling several kilometers underground, the water eventually re-emerges elsewhere in the valley. This journey — from the surface, into the earth, and back out again — is what makes chantoirs such a distinctive feature of this corner of Wallonia's landscape. Why is it also called Chantoir des Faux Monnayeurs? The site is sometimes referred to by a second name, Chantoir des Faux Monnayeurs, meaning "Counterfeiters' Sinkhole." This reflects a local tradition of giving chantoirs colorful, often folkloric names tied to stories or legends associated with a given spot — in this case, one suggesting that the underground passages nearby were once used as a hideout by people involved in illegal coin-minting. Why is the area around Adzeux so rich in chantoirs? The Vallon des Chantoirs lies along a band of limestone belonging to the Calestienne, a geological strip running through southern Belgium composed of Devonian limestone that is especially prone to karst processes. Within the valley itself, which extends from Louveigné to Remouchamps, roughly seventy distinct chantoirs have been identified so far — making this one of the most densely karstified areas in the Ardennes. The sheer number and variety of these sinkholes attract the interest of geologists and speleologists alongside travelers looking for lesser-known natural sights. How can you visit Chantoir d'Adzeux? The site lies along a network of marked walking trails running through the Vallon des Chantoirs, connecting Louveigné (including the Banneux area) with Remouchamps. Walking along the valley lets visitors spot several different chantoirs over a fairly short stretch, offering a good sense of the scale and variety of karst phenomena found here. It's worth keeping in mind that these sinkholes are natural formations with no tourist infrastructure built around them — their appeal lies in their geological curiosity and the scenic setting of the valley itself. Frequently asked questions What is a chantoir? It's a spot where a surface stream disappears underground, flowing into a network of channels carved through limestone by water over time. Which stream disappears at Chantoir d'Adzeux? The Banneway (Ru de Banneux), which flows through the former village of Adzeux. Where is Chantoir d'Adzeux located? In Adzeux, part of the village of Louveigné, in the municipality of Sprimont, Liège province, Belgium. How many chantoirs are there in the surrounding valley? In the Vallon des Chantoirs, stretching from Louveigné to Remouchamps, around seventy chantoirs have been identified. Why is it also known as Chantoir des Faux Monnayeurs? It's an alternative local name referencing legends about counterfeiters said to have hidden in the underground passages nearby.
