Nature in Switzerland

Seeli

Seelisberg

Seeli is a small lake in Seelisberg, in the canton of Uri, central Switzerland. Locals call it the Seelisberger Seeli, and it lends its name to the whole village, which sits on a terrace high above Lake Lucerne. Where is Seeli and what is it like? The lake lies at roughly 738 m above sea level, below the village at the foot of Niederbauen, the local home mountain. It covers about 18 hectares and reaches a depth of around 37 m. Underground springs feed it for the most part. Water leaves through karst rock towards Lake Lucerne, so there is no obvious stream flowing out. Can you swim here? Yes. A Naturbadi, a simple natural bathing area, operates on the shore. Entry is charged: according to the Lucerne regional tourism listing, adults pay CHF 5 and children CHF 3. The kiosk opens from about mid-May until early September. In high summer the water warms above 20°C, and some sources report up to 24°C. A campsite with a natural setting sits beside the lake as well, which suits families planning a longer stay. How do you get to Seeli? From Stans station, take Postauto bus 311 to the stop Seelisberg, Geissweg, a short walk from the water. By car you reach Seelisberg by the road climbing from the lakeside valley. Parking can fill up on hot weekends, so arrive in the morning during the season. What else is there to do nearby? Seeli works as a starting point or rest stop for several walks. The Förster-Trail loop around Seelisberg leads from the lake via Brunni and Waldweidli up to Marienhöhe and back to the village. Longer hikes in the area combine views of the lake, forest and the Niederbauen slopes. Check trail conditions before setting out in poor weather. Seelisberg also lies on the Weg der Schweiz, the path around Lake Uri, so a swim fits neatly into a day of walking. When should you visit? Summer is best, from June to early September, when the bathing area and kiosk are open. In spring and autumn the lake is a quiet walking goal without entry fees or crowds. Winter is calm, and visitors come mainly for Alpine views. Frequently asked questions Is there an entry fee at Seeli? Using the Naturbadi costs CHF 5 for adults and CHF 3 for children. Walking around the lake needs no ticket. How deep is Seeli? Its maximum depth is about 37 m, over a surface of around 18 hectares. Can you stay overnight by the lake? Yes, there is a campsite at Seeli in a natural setting. How do you reach it without a car? Take Postauto 311 from Stans station to Seelisberg, Geissweg.

Geltenbachhöhle

Kandersteg

Geltenbachhöhle is a cave system in the Gastern Valley (Gasteretal) near Kandersteg, in the Bernese Oberland. The Geltenbach stream bursts from an opening high in a rock face and plunges into the valley as the Geltenbachfall waterfall. What is the Geltenbachhöhle? It is a karst spring: the water does not run along the surface but emerges straight out of the mountain. Surveys carried out since the 1970s put the mapped passages at roughly 1.3 km, with a vertical drop of about 50 m. For a long time the spring area counted among the last unexplored corners of Switzerland, and exploring the cave remains difficult and demands caving expertise. What can you see there? Most visitors come for the waterfall, reported at around 70 m high. A viewpoint sits along the trail leading deeper into the valley. The cave itself is the domain of experienced cavers rather than a self-guided attraction. The flow changes from day to day: when water levels rise, the cave mouth turns into the source of a thundering cascade. How do you get there? From Kandersteg a route leads into the Gasteretal through the Chluse gorge. A hiking loop with views of the falls covers about 15.5 km. The valley is narrow and car access runs through a tunnel with alternating one-way traffic, which can carry a fee. Another option is the bus from Kandersteg to the Sunnbüel valley station, the cable car up, then a walk down via Spittelmatte, the old Gemmi Pass route and the Chluse to Eggeschwand (7.8 km, about 2 h 20 min, medium difficulty). Hotel Waldhaus stands along the way and offers a good view back to the falls. When should you visit? Choose the warm months, when trails are dry and the valley is in bloom; the Gasteretal is known for alpine wildflowers, including rare species. Sturdy hiking boots are a must. After snowmelt and heavy rain the waterfall is at its most powerful. Frequently asked questions Can you enter the Geltenbachhöhle? The cave is difficult and explored by experienced cavers. Visitors admire the waterfall and the rock face the water emerges from. Where is the Geltenbachhöhle? In the Gasteretal near Kandersteg, canton of Bern. Do not confuse it with the Geltenschuss waterfall at Lauenen near Gstaad. How long is the cave? Mapped passages measure about 1.3 km, with a drop of about 50 m. Is the road into the valley toll-free? The road into the Gasteretal runs through a tunnel and driving in can cost a fee. Check current rules with Kandersteg tourism before you go.

Steigelfadbalm

Vitznau

Steigelfadbalm is a cave on the slopes of Mt. Rigi, in the municipality of Vitznau on Lake Lucerne (canton of Lucerne, Switzerland). It ranks among the most significant archaeological and palaeontological sites in Central Switzerland, and it suits hikers who want an Ice Age story at the end of a mountain walk. What is Steigelfadbalm? The cave sits in Nagelfluh, the conglomerate rock that makes up much of Rigi. In Swiss German, a "Balm" is a cave or rock overhang. The site lies at roughly 47.0175° N, 8.4941° E, close to Vitznau, where the Rigi rack railway begins its climb. Why is it important? Excavations led by Wilhelm Amrein ran from 1913 to 1937. They yielded more than 3,000 bones and fragments, about 90 percent of them from cave bears. These animals reached around 3.5 m in length, up to 1.75 m at the shoulder and roughly 1,500 kg, and lived between 130,000 and 20,000 years ago. Researchers at the University of Vienna later studied the material, and the site is known in the literature as a fossil-bearing bear cave in the Rigi conglomerate. The second claim to fame is human presence. Archaeologists found a small quartz point worked on both sides. Similar points belong to the Middle Palaeolithic, roughly 300,000 to 35,000 years ago. The quartz is not local and may come from the Uri Alps. It is the first evidence of Neanderthals in Central Switzerland. Later hunters used the shelter too: a flint knife and a bronze arrowhead point to the Neolithic and the Bronze Age. How do you get there? No road or railway reaches the cave. A mountain footpath leads to it, and you can start in Hinterbergen or at the Mittlerschwanden station of the Rigi Bahnen railway. Wear sturdy hiking boots; the slope can be slippery after rain. What will you see? An information board by the cave explains the archaeological finds. The cave itself is a natural rock niche, not a developed underground route, so do not expect visitor facilities. The excavated material is not displayed on site; cave bear material is shown in Lucerne, and the Lucerne cantonal archaeology service holds the archaeological collections. When should you visit? Late spring to autumn is best, when Rigi paths are dry and free of snow. Plan the walk for daytime, as the cave has no lighting. Rigi Guest Service in Vitznau can advise on the route and current conditions. Frequently asked questions Can I visit Steigelfadbalm without a guide? Yes. The cave lies by a publicly accessible mountain path, and an information board stands at the site. Is the cave linked to Neanderthals? Yes. A quartz point found here is regarded as the first evidence of Neanderthals in Central Switzerland. Why are there so many bear bones? Cave bears sheltered here during the Ice Age. More than 3,000 bones and fragments survive, mostly from these animals. Where does the hike start? In Hinterbergen or at the Mittlerschwanden station of the Rigi Bahnen railway.

Grotte aux Fées

Saint-Maurice

Grotte aux Fées (Fairy Cave) in Saint-Maurice is a limestone show cave set in the cliffs above the town, in the Swiss canton of Valais. It holds the title of Switzerland's first cave opened to visitors, and its star feature is an underground waterfall of roughly 77 metres. What will you see inside? A narrow gallery leads you deep into the rock. At the end you reach a small lake fed by the waterfall, which is billed as the tallest in any show cave. The cave formed as water slowly dissolved the limestone, and you walk along a prepared path, so no caving gear is needed. Where does the name come from? According to the Historical Dictionary of Switzerland, "Grotte aux Fées" is a label shared by several caves across Valais, many of them once fortified. The Saint-Maurice one is the best known. It was first called "trou des fayes", meaning "sheep hole", and only later became linked with fairies. In 1863 a canon named Gard set it up for visitors, and in 1865 it passed to the Sisters of Saint-Maurice. It has welcomed tourists for over 150 years. How do you get there? Saint-Maurice sits in the Rhône valley on the rail line between Lausanne and Martigny, so the town is easy to reach by train. From the centre, a climb of around half an hour takes you to the entrance. The path is steep, so wear sturdy shoes. When should you go, and how long does the visit take? The cave opens seasonally, roughly from March to November. The guided visit lasts a few dozen minutes. Sources quote different route lengths, from about 500 metres to a kilometre, so treat any figure as approximate. Hours and prices change each season, so check the Saint-Maurice tourist office before you set out. The air inside stays cool all year, so bring a jacket even in summer. What else is nearby? The cave entrance doubles as the meeting point for summer tours of Fort de Cindey, a fortification built into the rock. In Saint-Maurice itself, the abbey and the castle with its exhibitions are worth a stop. Swiss Federal Railways (SBB) sells day-trip packages that combine the cave with a castle visit. Frequently asked questions Is there an older show cave in Switzerland? No. Grotte aux Fées was the first cave in the country opened to the public. How tall is the waterfall? About 77 metres, and it is the highlight of the route. Is it suitable for children? Yes, the route is organised and safe, though the approach to the entrance is steep and the inside is cool and damp. Can you reach it by public transport? Yes. Trains stop at Saint-Maurice, and from there you walk uphill to the entrance.

Cave of Sainte-Colombe, archaeological site of the Bronze Age, the Roman period and the Middle Ages

Haute-Sorne

The Sainte-Colombe Cave is a karst cavern with a chapel built into it, set in the municipality of Haute-Sorne beside the village of Undervelier in the Swiss canton of Jura. People sheltered here in prehistory, and the site later became a destination for pilgrims. Entry is free and you explore on your own. Where is it and how do you get there? The cave sits on the left bank of the Sorne, in a gorge north of Undervelier, between Les Forges and Undervelier. It lies right beside main road 248.4, which links the Delémont basin with Bellelay, so drivers can park next to the entrance (Route Principale 14, 2863 Undervelier). It stands at about 531 m above sea level, near 47.307 N, 7.219 E. Walkers can start from Bassecourt; the hike takes roughly three hours. What will you see? Inside is a single chamber 26 m wide, 7 m high and 30 m deep, opened by a huge portal. A chapel stands within the cave, and its present look dates from around 1900. Water drips from the ceiling and is gathered at the foot of a stalagmite. It has long been credited with healing powers, and the sick still come for it, along with mothers bringing weak children. What is the history of the site? The rock shelter was used in the Stone Age: excavators found bones and worked flint, plus remains of beaver, elk and ibex. Occupation was densest in the Middle Bronze Age, and pottery from the Middle and Late Bronze Age (about 1500 to 1000 BC) is the core of the finds. Iron Age objects, Gallo-Roman pottery and medieval pottery show the cave stayed in use over the centuries. Auguste Quiquerez dug here in 1868 and Frédéric-Édouard Koby in 1942, and M. Schenardi studied the Bronze Age material in 1994. Earlier digging badly disturbed the layers. The pilgrimage site was expanded in the late 18th century by Prince-Bishop François-Joseph Sigismond de Roggenbach, between 1782 and 1794. The cave honours Saint Colombe, a young martyr from Sens. Why she was chosen for this cave is unknown; a local legend says she stayed here to pray. When should you visit? The cave is open with no time restrictions all year. It gets busiest on 15 August, when the Jura stretcher-bearers hold their annual pilgrimage. For quiet, pick another day. It stays cool inside even in summer, so bring a warm layer. Photography is allowed. FAQ Is there an entrance fee? No. Entry is free and unrestricted. How long does a visit take? The interior takes about 15 minutes; the walk from Bassecourt takes much longer. Why is it named Sainte-Colombe? After the martyr of Sens. The reason for linking her to this cave is not clear. Is it a working church? It is a pilgrimage chapel, with an annual pilgrimage on 15 August and ordinary visitors the rest of the year.

Glacière de Monlési

Val-de-Travers

Glacière de Monlési is a natural ice cave in the municipality of Val-de-Travers, canton of Neuchâtel, in the Swiss Jura. Cold winter air sinks into a karst shaft and stays trapped there through summer, so ice remains underground all year. It is regarded as the largest underground ice deposit of the Jura arc. What is the Glacière de Monlési? It is a karst sinkhole with three shafts leading down to a large chamber filled with ice. The entrance sits on a high plateau at roughly 1,127 m above sea level, and the main shaft is about 20 m deep. Ice volume is estimated at 6,000 m³, although some sources quote up to around 10,000 m³. The air inside hovers near 0 °C. The site lies above the village of Couvet and is protected as a nature reserve. How do you get there? Most hikes start in Saint-Sulpice or at the Les Sagnettes bus stop (Col des Sagnettes) on the road between Fleurier and La Brévine. The cave is often combined with the Corridor aux Loups in one loop, and some routes also pass Lac des Taillères. The turn-off is not marked on any trail sign, so carry a map or a GPS track. What is the descent like? The largest opening hides between trees and bushes. A steep path with a safety cable leads to the entrance, followed by a metal ladder. Hiking sites grade the descent T3: you need sure feet, a head for heights and good footwear. What should you bring, and when should you go? a headlamp, because there is no lighting inside, a warm jacket and gloves, shoes with good grip, since ice and ladder rungs can be slippery. The recommended season runs from April to October, when the approach is dry and the ice is still visible. Frequently asked questions Can you visit Glacière de Monlési all year? Ice is there year-round, but visits are recommended from April to October. In winter the path and ladder ice over and the approach gets much harder. Do you need caving gear? No, this is not a technical caving trip. A headlamp, warm clothing and sturdy boots are enough, but you must be fit and comfortable with heights. Where do you start? Les Sagnettes bus stop and Saint-Sulpice are good starting points. Check the Neuchâtel regional transport timetable for current connections. How long does the trip take? Loops via the Corridor aux Loups or Lac des Taillères take a few hours, while the walk from Les Sagnettes straight to the cave is shorter. Timing depends on the route you pick.

Pfaffenloch

Toffen

Pfaffenloch is a cave in the municipality of Toffen, canton of Bern, in Switzerland's Gürbe valley. It sits on a wooded slope and works best as a short forest walk with a good helping of local folklore, not as a ticketed attraction. What is the Pfaffenloch? Wikidata lists it as a cave in Toffen, at roughly 46.844 N, 7.484 E. Tradition holds that two monks, Ulrich and Cuno, lived here in 1072, linked to the Cluniac order. They were said to be devout yet fond of rowdy feasting. This is folk tradition, not documented history. Where does the name come from? "Pfaffen" once covered the lower clergy generally and turned derogatory only around the Reformation. The name therefore reads roughly as "the clergy's hole". A spring nearby was reputed to ease chest complaints. Which legends surround it? A supposed tunnel to the ruins of Rüeggisberg monastery, almost five kilometres away. Nothing suggests it ever existed. Helpful dwarfs from the Leuenberg who vanished when someone touched their milk jug. A dwarf's cow whose cut-off flesh grew back. A farmer who finished work early on Saturdays after a dwarf made him hear a faraway bell. How do you get there? The nearest village is Toffen, between Bern and Thun. From the spot called Guetebrünne the walk takes about 10 minutes on an unpaved, steep path, partly up stairs. The Pfaffenloch also appears as a stop on the Gürbetaler Höhenweg, which follows the Längenberg moraine near Gantrisch Nature Park. One route description gives an altitude of about 881 m. Can you go inside? No. After a rockfall in 2017 the area is practically inaccessible, and the cave itself has collapsed. Wear sturdy shoes, and a helmet near the slope. Check closures and signs. In December 2022 a visitor found the suggested path blocked and climbed the hill above the cave by the regular hiking trail. What else is in Toffen? The village name is tied to tuff stone, quarried here from Roman times until 1983. Roman-era finds came from the old tuff pit. In the 13th century Toffen was a lordship of the barons of Belp-Montenach. Frequently asked questions Is there an entrance fee? No. It is a trailside spot with no ticket office or visitor facilities. Can I enter the cave? No. It has collapsed, and since the 2017 rockfall the area is largely closed to visitors. How long is the walk? About 10 minutes from Guetebrünne along a steep, unpaved path. Is the tunnel to Rüeggisberg real? No. It is oral tradition only; no underground passage has been documented.

Hölloch Cave

Stalden

Hölloch is a huge karst cave system in the municipality of Muotathal, canton of Schwyz, Switzerland, with its visitor base in the hamlet of Stalden. The surveyed passages run for more than 200 km, placing it among the longest caves in Europe and the world. A short section is open to ordinary visitors on guided tours, so you can sample this underground maze without caving experience. What exactly is Hölloch? It is a multi-level network of tunnels, fissures and large chambers carved into limestone by water. Published lengths range from roughly 197 km to over 211 km depending on survey date, and the system is deeper than 900 m. Explorers keep finding new passages, which is why the figures keep shifting. Who found it? Local mountain farmer Alois Ulrich is credited with the discovery: in 1875 he climbed in with a ladder and a lantern. From 1905 there were efforts to develop the cave commercially, and it opened to the public in 1906, but few visitors came. A flood in 1910 and lack of money ended further plans, and the cave was largely forgotten during the world wars. Systematic exploration took off in the 1950s, when the mapped length grew quickly. How can you visit? Entry is only possible with a guide. Tours start at the Hölloch Center on Stalden in Muotathal, and bookings go through the operator Trekking Team. Short guided tour: about two hours covering the first 700 m, in groups of up to 30 people. Beginner tour: around three hours through the developed part of the cave. Longer expeditions, such as the Hölloch Challenge (about six hours), involve crawling, climbing and good fitness; groups of six or more. Children can join from age 9. Prices vary by season and tour, so check the current rates with the operator. What should you bring? The cave is cold, and the floor can be wet and slippery. Wear warm layers and shoes with good grip. A helmet and light are supplied as part of the tour. On longer routes expect tight squeezes and ladders. Frequently asked questions Can I enter Hölloch on my own? No. Visits are in groups with a qualified guide. How long is the shortest tour? About two hours, covering the first 700 m or so. Is it suitable for children? Yes, from age 9, on family-friendly and beginner routes. How long is Hölloch? Depending on source and survey date, between about 197 km and over 211 km, and exploration continues.

Höllgrotten

Edlibach

Höllgrotten is a network of linked dripstone caves in the Lorzentobel gorge in the canton of Zug, central Switzerland. They sit on the border of the municipalities of Menzingen and Neuheim, near Edlibach, while the entrance address (Lorzendamm 28) is listed under Baar. You tour them on your own along a marked route. What are the Höllgrotten? The caves formed after the last ice age. Lime-rich spring water deposited layer after layer of tufa, building stalactites and other flowstone shapes, some several metres long. The grottos lie south of a widening of the gorge known as the "Höll", which gave them their name. How were the caves found? Tufa was quarried here from the first half of the 19th century. Quarrying exposed the first grotto in 1862, and it opened to visitors in 1885–1887. Five more caves turned up in 1892 and 1902; they were joined together and opened as well. A family foundation has run the site since 1942, and since 2012 a new route leads to the upper grotto. What will you see inside? The route runs downhill through a series of chambers with dripstone, pools and damp, dark passages. The circuit takes about 45 minutes. It is cold and wet inside, so bring warm clothing and waterproof shoes. How do you get there? Drive or cycle from Baar. The last stretch of roughly 3 km through the forest follows Baarburgstrasse, which is closed to general traffic. On foot, it is about a 25-minute walk from the Lorzentobelbrücke stop on the Zug–Menzingen bus line, a good starting point for a walk through the woods and gorge. When should you visit? The season runs from 1 April to 31 October, with daily opening in all weather. Published opening hours differ between sources, so check hoellgrotten.ch before you set out. The temperature underground does not follow the seasons, which makes the caves a sound choice for a rainy day. Who is it for? Families with children and nature lovers. Dogs on a lead are allowed, and a restaurant with a garden terrace stands nearby. A storyteller runs regular programmes for children and for adults and teenagers from 16; booking is required. Frequently asked questions How long does a visit take? The self-guided circuit takes about 45 minutes. Are the Höllgrotten in Baar or Menzingen? The entrance address is Baar, but the Historical Dictionary of Switzerland places the caves on the border of Menzingen and Neuheim, close to Edlibach. What should I bring? Waterproof shoes and warm clothes, because the caves are cold and damp. Is this the same as the Hölloch in Muotathal? No. The Hölloch in Muotathal is a separate, vast cave system in the canton of Schwyz. The Höllgrotten are smaller dripstone caves in the canton of Zug.

Saint-Léonard underground lake

The Saint-Léonard Underground Lake (French: Lac souterrain de Saint-Léonard) lies inside a hillside in the municipality of Saint-Léonard, in the Swiss canton of Valais, roughly halfway between Sion and Sierre. It is regarded as Europe's largest natural underground lake that visitors can tour by boat. What is it? The cave sits beneath vineyard slopes, tens of metres below the surface. The lake measures about 300 m long, 20 m wide and up to 10 m deep. The air stays around 15°C all year, so it feels cool in summer and mild in winter. Europe's largest artificial underground lake is the Seegrotte in Hinterbrühl, Austria, built by people. Saint-Léonard, by contrast, is entirely natural. What does the visit involve? The whole tour happens on the water. Visitors board large rowing boats that carry up to 40 people. The trip lasts around half an hour, with a guide explaining the cave's story in French, German and English. Lit sections show the rock ceiling and walls reflected in the still surface. What is its history? Official accounts say the cave was first entered in 1943, when the water level dropped in spring. Jean-Jacques Pittard is named as its explorer. The lake opened to the public in 1949 and has been a regional attraction ever since. How do you get there? The entrance is at the foot of the hill in Saint-Léonard, at about 46.26°N, 7.43°E. Sion and Sierre lie on either side of the village, so the drive from either is short. When should you go? The attraction is seasonal, running from March to November. Check lac-souterrain.com for current hours and prices before you travel, as they vary through the season. Because the temperature underground is constant, it works well on a rainy day. Bring a light jacket on hot days. What else is nearby? The Sierre and Sion area is the heart of Valais wine country. After the cave you can stroll among the vineyards on the Rhone valley slopes or drive on to Sion or Sierre. Frequently asked questions Is it the largest underground lake in Europe? It is the largest natural underground lake in Europe open to visitors by boat. The artificial Seegrotte in Austria covers a larger area. How long does the tour take? The guided boat ride lasts about 30 minutes. Allow an hour including the walk in. Which languages do the guides speak? French, German and English. Can you visit in winter? The cave is open seasonally, from March to November. It is closed to visitors in the remaining months.

Nidlenloch

Oberdorf (SO)

Nidlenloch (also spelled Nidleloch) is a vast cave system inside the Weissenstein ridge above Oberdorf in the Swiss canton of Solothurn. With about 7.5 km of passages and a depth of roughly 400 metres, it ranks among the largest caves in Switzerland and is the deepest in the Swiss Jura. The entrance sits among meadows and forest on the ridge, close to the hiking trails that overlook Solothurn. What kind of cave is Nidlenloch? It is a karst cave carved into Jura limestone, mostly dry and alpine in character. There are no lights or walkways here. Visitors find a natural network of passages, shafts and squeezes that calls for a headlamp and sturdy clothes. For most walkers the cave is a stop on a Weissenstein hike, while going inside is an expedition for experienced cavers or for people in a guided group. What is its history? The cave first appears in print in 1828, when the geologist Franz Josef Hugi reported pushing about 350 metres inside; locals almost certainly knew it earlier. In 1868 an engineer named Moser drew a 1:1,000 plan and cross-section of the part then explored. Between 1889 and 1891 teams led by Forster and Rotschi climbed down several small shafts on rope ladders. Franz Held later led more than 60 expeditions, and by 1909 the cave counted among the deepest known anywhere. A local research group, the Arbeitsgemeinschaft Nidlenlochforschung, has worked here since 1975 and found many new passages after re-surveying the known sections. How do you get to Nidlenloch? The entrance is roughly five minutes on foot north of the Hinter Weissenstein restaurant. You can ride the cable car up from Oberdorf, or walk from Solothurn through the Verena Gorge and past the hermitage. A well-known day hike links Solothurn, the gorge, the Weissenstein and Oberdorf, and the cave entrance makes an easy detour from the ridge. Can you go inside? The entrance is locked. Experienced cavers can collect the key from the Hinter Weissenstein restaurant, for a fee and during the restaurant's opening hours. Going in alone is discouraged. Beginners should join a guided tour, which has to be arranged in advance. The Weissenstein section of the Swiss Alpine Club runs full-day cave outings, for example one on 24 October 2026 that starts at the lower cable car station. Check current prices and rules before you travel. What else is nearby? In Oberdorf, at the foot of the mountain, you can see dinosaur tracks about 145 million years old. The Weissenstein is also one of the Jura's main viewpoints, with Alpine panoramas in clear weather, and the Verena Gorge with its hermitage is a classic trailhead. Frequently asked questions How long and how deep is Nidlenloch? Sources vary: length around 7.5 to 8 km (one gives 7,561 m) and depth between about 394 and 407 metres, depending on when and how it was surveyed. Is Nidlenloch open to tourists? There is no ordinary show-cave route. The entrance is locked and the key comes from the Hinter Weissenstein restaurant. Without experience, book a guided visit. How far is the entrance from the restaurant? About five minutes on foot to the north. When is the best time to visit? During the hiking season, when the cable car and restaurant are running. Guided trips into the cave are also held in autumn.

St. Beatus Caves

Sundlauenen

St. Beatus Caves in Sundlauenen, a village in the municipality of Beatenberg in the canton of Bern, are among Switzerland's best-known show caves. They sit on the northern shore of Lake Thun, right at the water's edge. The cave system is full of dripstone formations, and visitors can walk a lit route past waterfalls and finish in a small museum. What are the St. Beatus Caves? Water carved the caves into the Niederhorn massif. They take their name from Beatus, a monk and hermit venerated as a saint, who according to legend sheltered here. What is documented is that hermits lived in the caves until the Middle Ages. The full system is far bigger than the visitor section, and sources give different figures for the explored length, running to well over ten kilometres. What will you see inside? About one kilometre of passages is open and illuminated. The path winds through chambers hung with stalactites, along narrow gorges and beside falling water. The circuit has 297 steps and climbs and descends roughly 87 metres in total. Allow about an hour. You explore at your own pace with information boards and a free audio guide. The cave museum, redesigned in 2013, explains how the caves formed and were discovered, displays prehistoric finds and includes a model of the Niederhorn massif. Entry to the museum is included in the ticket. What should you bring? The air stays at a steady 8-10°C and is very humid, so pack a warm layer and shoes with good grip. The steps are many and can be slippery, and the route is not suitable for wheelchairs or anyone who struggles with stairs. How do you get there? The caves lie beside the lake road between Thun and Interlaken. You can arrive by car, by bus or by boat across Lake Thun. From the car park and stop, a short uphill walk along a stream leads to the entrance. When is the best time to visit? The caves are most fully open from spring to autumn, and opening hours and prices change from year to year, so check the official website before you travel. On a hot day the cool interior is a bonus, and going early helps you avoid the biggest groups. Frequently asked questions How long does a visit take? About an hour. The route is roughly 1 km, and the museum adds a little time. Do I need a guide? No. The visit is self-guided, with information boards and an audio guide. How cold is it in the caves? A constant 8-10°C, so bring warm clothing even in summer. Are the caves wheelchair accessible? No. The route has nearly 300 steps and is steep, so it is not suitable for wheelchairs.

Kobelwald Kristallhöhle

Kobelwald

Kristallhöhle Kobelwald is a show cave in the village of Kobelwald, part of the municipality of Oberriet in the Swiss canton of St. Gallen, in the Rhine Valley (Rheintal). Visitors come for its walls and fissures lined with grey and white calcite crystals, which make it one of the most admired show caves in Switzerland. What will you see inside the cave? The route leads through narrow passages and chambers glittering with calcite. Along the way you pass a small underground lake and a waterfall. The air stays cool at about 8.5°C all year, so bring a warm layer even on a hot day. According to the showcaves.com catalogue, the whole cave is about 665 m long with a vertical range of roughly 91 m. Only a section is open to the public. Sources quote different lengths for the guided route, from about 128 m to about 256 m, so check the cave's own website for current details. Can you explore it on your own? No. Entry is only possible with a cave guide, and groups go in together. Passages are tight and damp and the floor can be slippery, so wear sturdy closed shoes. How do you get there? Kobelwald lies in the Rhine Valley, close to the Austrian and Liechtenstein borders. Several car parks sit near the entrance. From the nearest one, P3 "Tanzplatz", it is a walk of roughly 10 minutes along a forest path. When should you visit, and what does it cost? The cave opens seasonally, roughly from Easter until early November. On Sundays and public holidays you can join a tour without booking ahead. On other days groups visit by prior arrangement, and during the peak of the summer school holidays it opens daily. Hours differ slightly between sources, so confirm them at kristallhoehle.ch before you travel. The most recent price data lists adults at about CHF 10 and children aged 6 to 14 at about CHF 5. Prices may change from season to season. What else is nearby? The Rheintal is a broad, flat valley framed by the Appenzell hills and the Alpstein range, and the area around Oberriet offers quiet walks through meadows and orchards. A visit to the cave takes about an hour, so it pairs easily with a short hike. Because most of the time is spent underground, it also works well as a rainy-day outing for families. Frequently asked questions Can I enter Kristallhöhle Kobelwald without a guide? No. Visits are only possible with a cave guide. How far is the walk from the car park? From car park P3 "Tanzplatz" it takes about 10 minutes on foot. Is the cave open all year? No. The season runs roughly from Easter to early November. Sundays and public holidays are the safest choice, since no reservation is needed then. How cold is it inside? Around 8.5°C throughout the year, so dress warmly. Is it suitable for children? Yes. Children aged 6 to 14 pay a reduced price, and the waterfall and crystals usually impress younger visitors. The route does require steady footing and good shoes.

Schafloch

Sigriswil

Schafloch is a natural cave tunnel running through the Sigriswilergrat ridge above Lake Thun, in the municipality of Sigriswil (canton of Bern, Switzerland). Hikers can walk straight through it, which makes it one of the more unusual stops on trails in the Bernese Oberland. What is the Schafloch? It is a rock passage cutting through the ridge beneath the Sigriswiler Rothorn. It is not a developed show cave with lighting and a ticket desk. It is a wild mountain crossing used by walkers around the Justistal valley. The interior is dark and gently curved, so a light source is essential. How do you get to the Schafloch? Most routes begin high above Lake Thun, in the Justistal. From Sigriswil village you follow the narrow Justistalstrasse, which forks after roughly a quarter of an hour by car. From there, route descriptions put the walk to the entrance at a little over an hour. The second common option starts at the Schwanden Sagi car park and climbs via the Zettenalp pasture. The tunnel entrance sits at map point 1811. The cave is often combined with a longer loop up the Sigriswiler Rothorn, a tour also promoted by the Interlaken tourism board. What should you bring? A headlamp or a strong torch, as there is no lighting inside. Shoes with a solid grip, since the floor can turn slippery in rain or snow. An extra warm layer, because the rock keeps the passage cooler than the open slopes. What do you see on the other side? The eastern exit opens onto the Justistal valley and the peaks of the Bernese Alps. The contrast between the dark passage and the sudden wide view is the main reason walkers build the tunnel into their day. What is its history? The later Swiss general Guillaume-Henri Dufour visited the cave on 5 September 1822 and published an account of it. Engineers from Bern surveyed it in 1884. During the Second World War the Swiss army turned it into a defensive position, with blocking positions and ammunition stores at both ends. Remains of these works add a historical layer to the crossing. When should you go? Plan the hike for the snow-free months, generally late spring to autumn, in settled weather. Early in the season and after rain, check trail conditions: snow patches can linger higher up and the tunnel floor gets slick. Frequently asked questions Do I need a torch for the Schafloch? Yes. The tunnel has no lights and is slightly curved, so moving through safely without a headlamp is difficult. Where is the easiest place to start? The two usual options are the Justistal valley, reached from Sigriswil along the Justistalstrasse, and the Schwanden Sagi car park with an ascent via Zettenalp. Is it a cave known for cave bear finds? The sources give no confirmation of that. The Schafloch is known mainly as a walk-through passage and a former military position, not as a paleontological site. Can I combine it with a summit? Yes. The Schafloch often forms part of the route to the Sigriswiler Rothorn, where the tunnel is a memorable highlight.

Täuferhöhle

Bäretswil

Täuferhöhle, the Anabaptist Cave, sits in the woods near Bäretswil in the canton of Zurich. Persecuted Anabaptists once hid here. Today it is a quiet, free stop on a short walk through the Zürcher Oberland. What is the Täuferhöhle? It is a small erosion cave in conglomerate rock, about 30 metres long. A huge portal opens onto a single cavern with bare walls. One hiking description puts the rocky bowl in front at roughly 40 metres across. Daylight reaches the main chamber well. A smaller, dark cave nearby needs a torch. The site lies at about 47.317 N, 8.886 E. Why is it called the Anabaptist Cave? The Zurich Anabaptists broke away from Zwingli's church in 1524, mainly over adult baptism. According to the Historical Dictionary of Switzerland, the movement had a strong following in Bäretswil from 1525. When the authorities began to pursue them, the cave served as a refuge in the 16th and 17th centuries. Tools, pottery shards and combs have been found inside, and people probably used the cave as early as the Stone Age. How do you get there? A forest path leads to the cave, and the final stretch is a steep descent on steps. In 2007 an iron walkway replaced the old wooden one. The walk is short but the ground is uneven, so wear sturdy shoes. Driving can be awkward. The route runs through Ringwil, and many farms along the way have poor signage, so download an offline map first. A circular hike is often easier. The railway operator SOB describes a loop from Gibswil via Wissengubel to the cave. What is there on site? free entry with no opening hours, a fire pit for barbecues, information boards on the area's history, mentioned by visitors, benches and a small stream in the rock bowl. The cave suits a picnic and is also used for open-air services. When should you visit? Dry weather from late spring to autumn is best, when the steps and path are not slippery. The gorge stays damp after rain, and the descent can ice over in winter. Frequently asked questions Is there an entry fee? No. The cave is open at all times at no charge. Do I need a torch? Not for the main cavern, which gets good light. Bring one only for the small dark cave next to it. Can I light a fire? There is a fire pit for barbecues. Bring your own wood and leave the place clean. Who hid in the cave? Anabaptists, members of the movement that split from the Zurich Reformation in 1524. They used it in the 16th and 17th centuries. Where should I park? The access road winds through Ringwil on small roads with few signs, so check the route before you go. Walking from Gibswil can be simpler.

Aabach Wasserfall

Horgen

Aabach Wasserfall in Horgen is a waterfall in the Aabachtobel gorge above Lake Zurich, in the canton of Zurich. It drops on a side stream of the Aabach and is the highlight of an easy hike from Horgen toward the Au peninsula. What is this place? The Aabachtobel is a wild, rocky ravine through which the Aabach runs down to the lake. Along the way the stream forms small and large cascades, locally called "Giessen", and shallow rock basins where you can cool off in summer. The waterfall itself is not on the main channel. It sits on a tributary and falls over a rocky ledge, with a small pool and a fireplace nearby. It is at its strongest after rain and during snowmelt. In the lower gorge you can see exposed sandstone and marl layers of the Upper Freshwater Molasse, which adds interest for anyone curious about geology. Hikers also mention other stops: the medium-sized Bernhardsfall and a sealed gallery of an old mine below the forest path. How do you get to the falls? The best-known option is the Zurich hiking association's walk from Horgen through the Aabachtobel to the Halbinsel Au. It begins at the Horgen, Hüttenstrasse bus stop. The path follows the stream, using metal stairways, low rock steps and narrow passages between the rocks in places. After the third bridge the trail leaves the stream bed and climbs gently to the waterfall on the side stream. From there it continues up a wooded slope to a forest edge with a view, then to the Horgen, Käpfnach bus stop. A descent leads to the lake, and you follow the shore, partly on boardwalks through reeds, to Au. The route is 7.5 km long with 65 m of ascent and 200 m of descent, and it is rated easy. Approximate walking times from the start: Aabach bridge: about 30 minutes Käpfnach: about 50 minutes Ausee lake: about 1 h 20 min Au ferry landing: about 1 h 35 min Au station: about 1 h 55 min Komoot also lists loops from Horgen and from Au: a short easy one (around 6.3 km, under 2 hours), a longer one (around 12.5 km, about 3.5 hours) and a 9.5 km loop from Au (about 2 h 40 min). When should you go? Water volume is highest after rainfall and in spring thaw. In summer the basins in the stream bed are the draw. Rock and steps get slippery when wet, so wear shoes with good grip. What else is on the way? A viewpoint at the forest edge, then a lakeshore stretch with several spots where you can reach the water. You can add a loop around the small Auseelein pond and walk on to the castle in Au. A restaurant stands on the Au hill. Frequently asked questions Is the hike difficult? No. ZVV rates it easy, though there are metal stairs and narrow rocky sections. Where do I start? At the Horgen, Hüttenstrasse bus stop, and finish at Au railway station or the ferry landing. Where exactly is the waterfall? On a side stream, reached after the third bridge, where the path leaves the main Aabach channel. When does it look best? After heavy rain and during snowmelt.

Berschnerfall

Berschis

Berschnerfall is a waterfall of roughly 46 metres tucked into a wooded ravine above the village of Berschis, part of the municipality of Walenstadt in the canton of St. Gallen. It belongs to the Heidiland region, a short distance from Lake Walen, and drops over a rock step along the Berschnerbach stream. The walk is short and undemanding, so you can see a proper waterfall without committing to a full day in the mountains. What will you see? The fall is a single tall ribbon of water dropping into a shaded cleft. A wooden bridge spans the stream in front of it, and that is the viewing point; you cannot get any closer, so photos are taken from there. On the way up, the path follows the Berschnerbach, and the surrounding forest keeps things cool even on hot days. The return loop uses a natural path and passes two curiosities. The first is Ughürig Brunnä, a natural glacial pothole, a hollow in the rock ground out by ice and meltwater. The second is a Lourdes grotto, where benches under old trees make a good rest stop. How do you walk to the waterfall? The route starts in the centre of Berschis, where an information board explains the trail. The climb to the fall takes about 25 minutes and goes steadily uphill beside the stream until the ravine and fall appear after a bend. The full loop is about 3.6 km, takes around 1 hour 15 minutes and involves roughly 195 metres of ascent. It is rated medium difficulty, and the last stretch can be steep, so shoes with good grip help. How do you get to Berschis? By car it is about an hour from Zurich. By train, allow a little over 1 hour 20 minutes from Zurich. Take the train to Walenstadt, then a bus to the Berschis Unterdorf stop, which is close to the start of the trail. You do not need a car. When is the best time to visit? The fall looks best in spring during snowmelt and after heavy rain, when the stream carries plenty of water. In dry spells the flow can be noticeably thinner. Choose a day without rain, because wet roots and rock on the path get slippery. Check current trail conditions before setting out, since different sites list slightly different distances and walking times. What can you combine it with? Berschis is close to Lake Walen, so the walk fits easily with a lakeside visit or other Heidiland sights. The waterfall needs no more than half a day, which makes it a handy add-on to a longer stay in the region. Frequently asked questions How tall is the Berschnerfall? About 46 metres. How long is the walk? The climb from the village takes around 25 minutes, and the full loop via the glacial pothole and grotto about 1 hour 15 minutes. Can you reach the base of the fall? No. The trail ends at a wooden bridge with a view of the cascade, and there is no path beyond it. When does the waterfall carry the most water? In spring during snowmelt and after heavy rainfall. Can you get there by public transport? Yes. Take the train to Walenstadt, then a bus to Berschis Unterdorf.

Mattbachfall

Mels

Mattbachfall is a waterfall in the Weisstannental valley, in the municipality of Mels, canton of St. Gallen (Sarganserland region). The Mattbach stream drops here in two separate falls, an upper and a lower one, close to the head of the valley. The lower fall is a short stroll from the car park, so this is a quick scenic stop rather than a full-day outing. Where is Mattbachfall? The falls sit deep in the Weisstannental, a side valley branching off at Mels. The valley is known for its cascades: seven named waterfalls and dozens of unnamed ones are counted in the area. Mattbachfall is one of them, and from the car park you also get a view of the neighbouring Isengrindfall. The car park lies at roughly 46.9676 N, 9.2706 E. How do you get to Mattbachfall? By car, drive from Mels up the valley to the village of Weisstannen. Cross the bridge there and turn right onto a narrow road. After a few kilometres it ends at a house and a small parking area. The lower fall is under five minutes on foot from there. Parking and viewing cost nothing. Without a car, take the train and bus to the Weisstannen Oberdorf stop (about 1.5 hours from the region's larger towns), then walk roughly 5 km to the falls. What will you see? Two drops on a single stream. The lower fall is easy to reach, while the upper one takes more effort. The ground right beside the lower fall can be muddy, steep and slippery, especially on the left-hand side, where visitors scramble up for a closer look. It is not ideal for very small children. Isengrindfall is visible from the parking area, so one stop covers two waterfalls. When should you go? Early summer is best, when snowmelt feeds the stream and the falls carry the most water. The road is often usable already in April and May, before the mountain cable cars open for the season, which makes it a good spring alternative to higher routes. What else is nearby? Alpe Walabütz, an alpine hut near the falls known for its cheese and a popular cycling target (a Komoot route links it with Mattbachfall). The Muttenbach, Sässbach and Piltschina falls near Batöni: about 4 km and 500 m of ascent from Weisstannen, or 80-90 minutes on foot. Weisstannen village itself, a base for exploring further up the valley. Frequently asked questions Do I need to hike to reach Mattbachfall? No. Once you park, the lower fall is a few minutes' walk away. Is there an entrance fee? No, the site is open and free. Is it suitable for young children? Stay at the lower fall with little ones, as the slopes beside the water are steep and muddy. When does the waterfall carry the most water? In early summer, during the main snowmelt.

Batöni

Weisstannen

Batöni is a natural amphitheatre of waterfalls above the village of Weisstannen, in the Weisstannental valley of the canton of St. Gallen, Switzerland. Known as the Wasserfall-Arena Batöni, it lies in the Heidiland region and within the UNESCO-listed Swiss Tectonic Arena Sardona. What will you see at Batöni? Five waterfalls drop over steep rock faces into one basin, ranging from 45 to 86 metres in height. One hiking guide lists the Sässbach fall at about 86 m, the Piltschinabach at 81 m and the Muttenbach at 45 m. You can take in the whole arena at once, which makes it one of the most dramatic spots in this corner of the Alps. Chamois, deer and sometimes ibex are regularly seen nearby. How do you get to Batöni? Take a train to Sargans or Mels, then the postbus up to Weisstannen. Most hikers start at the Weisstannen Oberdorf stop and follow the Gufelbach stream. The round trip takes roughly 3 hours, covers 7 to 8 km and involves 530 to 590 m of ascent; sources differ slightly, and the difficulty is rated medium. The highest point of the loop is about 1,530 m above sea level. The site also lies on section 4 of Sardona World Heritage Trail no. 73, from Weisstannen to the Sardona SAC hut. What can you combine with the visit? Experienced hikers can continue over the Lavtinasattel pass to the Pizolhütte, passing the Wildsee, one of the five lakes of the well-known 5-lake hike. This is a demanding day of about 11.9 km, over 6 hours and around 1,600 m of climbing. A handy tip is to park at Wangs and use public transport to Weisstannen, so your car waits at the finish. When should you go, and what should you know? The route is usually clear only from early July, as snow and avalanche debris linger earlier in the season. Check trail conditions before setting out, especially after storms; the area was temporarily closed in 2022 because of storm damage. No facilities are listed along the way, so carry water and food. The basin sits inside the federal hunting ban area Graue Hörner, so stay on marked paths and follow the rules of conduct. Frequently asked questions How long is the walk to the waterfalls? About 3 hours round trip from Weisstannen Oberdorf. Is Batöni suitable for families? The trail is of medium difficulty with more than 500 m of climbing, so it suits children used to hiking. Can I get there by public transport? Yes, by train to Sargans or Mels and then postbus to Weisstannen. Will I see wildlife? Chamois, deer and ibex live in the area. It is protected, so watch from a distance.

Isengrindfall

Mels

Isengrindfall is a waterfall at the head of the Weisstannental valley, in the municipality of Mels, canton of St. Gallen, Switzerland (Sarganserland region). Its height is usually given as about 230 metres, which places it among the tallest waterfalls in Europe. What will you see? The Scheubsbach stream leaves the Isengrind rock wall in one long, free fall and lands in a basin called Walabütz. Even from a distance the drop looks dramatic. Visitors like to compare it with the Staubbach Falls at Lauterbrunnen, which stand roughly 60 metres taller. The fall sits at the end of the valley, framed by steep slopes. Below it, the power company Kraftwerke Sarganserland taps the water and sends it towards the Gigerwald reservoir, so the flow is partly managed. The valley's water drains eventually into the Seez river. How do you get there? From Mels, drive up the Weisstannental to the village of Weisstannen. Cross the bridge and follow the narrow road to the parking area where it ends. The Isengrindfall is already in clear view from there, so no hike is needed. Without a car, take a train to Sargans and a bus on to Weisstannen; you will then need to cover the remaining stretch to the road's end on your own. What else is nearby? A few minutes further on is the Mattbachfall, made up of two separate falls. In total the valley has seven named waterfalls and many unnamed ones. A different attraction is the Batöni waterfall arena above Weisstannen: a return hike of about 7 km (roughly 590 m of ascent, about three hours) along the Sardona World Heritage Trail. The hunting reserve en route often shows chamois, deer and ibex. When should you go? Early summer is best, when snowmelt feeds the stream and the fall carries the most water. Check local conditions before you set off, because mountain storms can close roads and trails for a while. Frequently asked questions How tall is the Isengrindfall? About 230 metres is the figure most often quoted. It comes from tourism sites, so it may vary slightly between sources. Do I need to hike to see it? No. There is a good view from the parking area at the end of the road in Weisstannental. When is the waterfall at its best? In early summer during snowmelt. Are there other waterfalls close by? Yes. The Mattbachfall is a few minutes away, and the Batöni waterfall arena lies near Weisstannen.

Reichenbach Falls

Geissholz

Reichenbach Falls (Reichenbachfälle) drop through a gorge near Meiringen and the hamlet of Geissholz in the Bernese Oberland, in Switzerland's Haslital valley. They rank among the tallest waterfalls in the Alps, and they are famous as the spot where Arthur Conan Doyle sent Sherlock Holmes and Professor Moriarty to their apparent deaths in "The Final Problem" (1893). How tall are the Reichenbach Falls? Five cascades make up the falls, with a combined drop of about 200 metres. The tallest single step measures around 90 metres. Travel guides quote other figures (anywhere from 110 to 250 m), depending on which stretches they count. The Reichenbach stream reaches the Aare valley right by Meiringen. How do you get to the falls? The easiest route is the Reichenbachfall-Bahn funicular. Its lower station sits at Willigen, roughly a 20-minute walk from Meiringen railway station. The line opened in 1899 and was rebuilt to the original design in 1999. Two cars carry 24 passengers each, and the ride climbs about 240 metres in a few minutes. From the top station, a short walk leads to the viewpoint over the falls. The funicular runs seasonally, from spring to early October (2 May to 4 October in 2026). Hours vary by month, so check the current timetable before you go. Access involves steps, so it is not suitable for wheelchairs or pushchairs. Dogs are allowed. What can you see there? a series of cascades and spray carried by the wind, strongest during the spring snowmelt, views over the Haslital valley from the upper platforms, Holmes references, including a memorial plaque along the path where the novel places the duel. In Meiringen itself, add the Sherlock Holmes Museum and a stroll through the town to your plans. The falls pair well with another Haslital stop such as the Aare Gorge. When is the best time to visit? The funicular season runs roughly from May to early October. Water volume peaks in spring and early summer, when snow melts in the mountains. In summer the funicular has its longest daily hours, and going early in the morning helps you avoid queues. Frequently asked questions Is there an entrance fee for the falls? The falls can be viewed freely, but the funicular ride needs a ticket. Check the operator's timetable for current prices. How much time should I plan? The funicular ride, a walk to the viewpoints and the descent usually take 1.5 to 2 hours, including the walk from Meiringen station. Can I walk up instead of taking the funicular? Yes. A path climbs from Meiringen. It takes about 20 minutes to reach the lower station, and the ascent beyond that is steep. Why are the falls linked to Sherlock Holmes? Conan Doyle chose them as the setting for the detective's supposed death in his 1893 story. That is why the area has Holmes references, including a museum in Meiringen.

Oltschibachfall

Unterbach

Oltschibachfall is a waterfall above the village of Unterbach in the Haslital, canton of Bern, halfway between Meiringen and Brienz. The Oltschibach stream drops down the mountainside above the Aare valley floor, and the cascade is easy to spot from the valley even though it sees far fewer visitors than the Reichenbach or Giessbach falls. How tall is Oltschibachfall? Published figures disagree. European Waterfalls gives a total drop of more than 200 m, including a single upper step of about 140 m. Bergwelten describes a plunge of roughly 140 m, while World of Waterfalls estimates about 260 m from the map contour lines. Several of these numbers are estimates, so treat them as an order of magnitude: this is one of the taller falls in the region. Where can you see it from? The main valley road: you can spot the fall from a distance while driving, but there is nowhere to stop. The side road near Meiringen airfield: Unterbachstrasse gets you closer, though the runway of the air base runs right beside it. Unterbach village: there is a parking area, and an unpaved track leads to a nearer viewpoint. The Gasthof Rössli in Unterbach also has a good view of the fall. Is there a hiking route? Yes. Bergwelten lists a loop from Unterbach past the fall to Meiringen: 8.4 km, about 3 hours, with 428 m of ascent, 408 m of descent and a high point of 965 m. Most of the way follows cool, shaded forest paths, and the fall is reached after a short walk through the woods. No mountain equipment is needed, but sturdy shoes help. When should you go? May to September is the recommended hiking season. The fall looks best after snowmelt or heavy rain, when the stream carries the most water, and can thin out in dry spells. The forest shade keeps the route comfortable on hot days. What else is nearby? The multi-tier Wandelbachfall, reported at over 300 m in total, lies close by, as do the better-known Giessbach falls on Lake Brienz and the Reichenbach falls near Meiringen. All are a short drive or train ride away, so they combine well into a one-day waterfall tour. Frequently asked questions Is there an entrance fee? No. The viewpoints and paths around Unterbach are freely accessible. Can I stop by the main road to look at it? No. From the main road the fall is visible only from afar. Park in Unterbach or use the side road near the airfield. How much time should I plan? The walk from Unterbach to the viewpoint is short. The full loop to Meiringen takes about three hours. Is it the tallest waterfall in the area? There is no clear answer: estimates of its height vary, and Wandelbachfall is reported as taller, so rankings are unreliable.

Simmenfälle

Lenk

Simmenfälle is a series of cascades on the Simme river in the upper Simmental valley, a short drive from the resort village of Lenk in the canton of Bern. In summer the river carries so much water that you hear the falls from the road. They are also the easiest trailhead for a walk up to the Simme's source. What will you see at the Simmenfälle? The main sight is the cascade itself, which you pass on a wide path right beside the water. Local accounts say the falls are not entirely natural: in 1702 rock was blasted to straighten the river's course, because the Simme had flooded the valley repeatedly. Published heights vary, since sources describe different stretches of the falls, so we give no single figure. A restaurant stands by the car park, and more places to eat lie further along the trail. How do you get there? From Lenk you can drive or take the bus to the stop called Lenk, Simmenfälle. Parking is at the Restaurant Simmenfälle, with extra spaces near the school on the Lenk–Simmefäll road. From there a broad, gently rising track leads past the cascades to the Rezliberg alp. Where does the walk continue? From Rezliberg, a short detour leads to the Siebenbrünnen (Sibe Brünne, "seven springs"), where the Simme begins. The water gushes from cracks at the foot of a limestone wall in a fan roughly 30 metres wide, fed by meltwater seeping from the glacier between the Wildstrubel and the Rohrbachstein. In summer up to 2,800 litres per second flow out of the seven springs. The longer loop continues to the Flueseeli lake and the unstaffed Fluhseehütte hut: about 10.8 km, 1,055 m of ascent, roughly 4 h 50 min, graded T3 (demanding mountain hiking), recommended June to October. Another option from the same start climbs to Iffigenalp, where you can eat and see the Iffigfall waterfall. When should you go? Summer and early autumn are best: trails are open and the river runs strongest after the snowmelt. In winter the area belongs to skiers and the paths to the source are not recommended. Check trail conditions and hut opening before setting out. Frequently asked questions Is there an entrance fee? The sources mention none for reaching the falls; only parking or a meal at the restaurant may cost money. How long does the falls alone take? The walk to the cascade and back is a short stop. Allow considerably more for Rezliberg and the Siebenbrünnen. Can you eat along the way? Yes. There are restaurants at the Simmenfälle, at Siebenbrunnen and on Iffigenalp, plus several fire pits. Where is the source of the Simme? At the Siebenbrünnen on the Rezliberg above Lenk, right at the foot of a limestone wall.

Iffigfall

Lenk

Iffigfall is one of the tallest waterfalls in the Bernese Oberland, set in the Iffigental valley above the village of Lenk in the Simmental (canton of Bern, Switzerland). The Iffigbach stream drops over a rock step of more than 100 metres, tumbling down in several stages. Access is free, and you need no climbing gear to reach it. What will you see? The first thing you notice is the sheer scale. Meltwater-fed Iffigbach breaks over successive ledges, and a cool spray drifts across the base. Published heights vary from about 70 m to over 100 m. Most sources, including the local tourist board, give a figure above 100 m. In winter the falls freeze into one of the region's favourite ice-climbing routes, roughly 140 m long. How do you get to Iffigfall? The simplest option is the PostBus from Lenk to the terminus at Iffigenalp, at the head of the valley. From there a trail leads downhill alongside the stream. It leaves the Iffigbach above the drop and swings in a wide curve to the foot of the falls, so you view them from below. Continuing all the way to Lenk makes a walk of about 8.8 km and around 2.5 hours. It is easy and mostly downhill, passing through the hamlet of Pöschenried. Shortly before Lenk, the small Lenkersee lake makes a pleasant stop. Can you start from Lenk instead? Yes. Walk from Lenk station via the Rohresee beside the Iffigbach to the waterfall, then continue uphill to Iffigenalp. Expect about three hours and roughly 580 m of ascent, with the bus as the easy way back. When should you go? The valley is best walked from late spring to autumn. Water volume peaks during snowmelt and after heavy rain. In winter, conditions depend on snow and ice, and the falls are seen as a frozen curtain. Check the current bus timetable to Iffigenalp before you set out, since services change by season. What else is nearby? Trails from Iffigenalp lead on towards Iffigsee lake and the Wildstrubel massif, so the waterfall slots easily into a longer alpine day. Around Lenk you can also see the Simmenfälle and the Siebenbrünnen spring, where water fans out over a width of about 30 m. A loop from Lenk covering these sights is about 16 km. Frequently asked questions Is there an entrance fee? No. The waterfall stands beside a public trail and entry is free. You only pay for the bus if you use it. How long does the walk take? Iffigenalp to Lenk takes about 2.5 hours, and the stretch to the falls alone is much shorter. Starting from Lenk via the Rohresee takes about three hours one way, with a climb. Is it suitable for children? The bus-up, walk-down version is easy and works well for school-age children. The ascent from Lenk is tougher. How tall is Iffigfall? Most sources quote more than 100 m, in several stages. A few lists give about 70 m, which comes down to a different way of measuring.
