Nature in Switzerland

Flachsee

Rottenschwil

Flachsee is a man-made lake on the Reuss river at Rottenschwil in the Swiss canton of Aargau, a few kilometres south of Bremgarten. It filled in 1975 in the backwater of the Bremgarten-Zufikon hydropower plant, as part of the wider Reusstal landscape restoration. Today it is a nationally important reserve for waterbirds and migrating birds, and one of the better birdwatching spots in the region. What is Flachsee and why visit? Shallow water, muddy margins and slow-moving stretches create a habitat that is rare in the surrounding, heavily engineered river plain. Since 1973 observers have recorded 212 bird species here. The area is listed in the federal inventory of water and migratory bird reserves (object no. 106) and protected under the WZVV ordinance. The Stiftung Reusstal foundation, based in the Zieglerhaus in Rottenschwil, is among those looking after the Reusstal. Which birds can you see? Breeding season: the lake is an important nesting site for the northern lapwing, alongside several other water and wetland birds. Spring and autumn: waders such as common snipe and green sandpiper stop over on exposed mud in the slower-flowing sections. All year: a mix of ducks and other waterfowl, with the highest species counts outside the breeding season. Observation facilities are placed along the paths, including a viewing mound and a covered hide on the recommended walking loop. The hide lets you watch birds without disturbing them, so bring binoculars or a telephoto lens. How do you get to Flachsee? The easiest public transport option is the PostBus to the Hecht stop in Rottenschwil. By car, park near the Reuss bridge in Rottenschwil, where the walk along the shore begins. The lake lies at roughly 47.328 N, 8.369 E. When should you go, and how should you behave? Variety peaks during spring and autumn migration, and lapwings breed in spring. Pack binoculars and warm layers, since the shore can be windy. This is a protected reserve, so stay on the marked paths, keep noise down and follow the on-site signs. Check stiftung-reusstal.ch before your visit for current rules, for example on dogs. Frequently asked questions Is Flachsee a natural lake? No. It was created in 1975 after the Bremgarten-Zufikon dam was built on the Reuss. How many bird species have been recorded? According to the canton of Aargau, 212 species since 1973. Where is the best place to watch birds? From the covered hide on the walking loop and from the viewing mound. How do I get there without a car? Take the PostBus to the Hecht stop in Rottenschwil, then walk a short way to the shore.

Etang de la Bressonne

Lozanna

Etang de la Bressonne is a small pond in Lausanne, canton of Vaud, beside the hamlet of Chalet-à-Gobet in the hills above the city. It sits at 849 m above sea level, covers 1.6 ha and reaches a maximum depth of 2.20 m. It makes an easy, quiet outing among meadows and woods, well away from the city centre. What is this place? The pond was created on former marshy pastures and is fed by three streams draining about 45 ha of land. In 1988 the site became a nature reserve and opened to visitors. The City of Lausanne owns the land and has drawn up a shoreline management plan that favours biodiversity. What will you see? A path of roughly one kilometre circles the water. Some trails have been closed to protect plants and animals, so stay on the marked route. A bird-watching screen stands by the shore, letting you observe waterfowl without disturbing them. Amphibians and dragonflies breed in the pond, including some threatened species, and spring and summer are the liveliest seasons. How do you get there? The nearest car park lies east of the pond, along Route des Paysans. From central Lausanne the drive takes a few minutes by car, and Chalet-à-Gobet is also a starting point for walks in the surrounding forests. Two spaces for visitors with disabilities are marked at the car park. Is it accessible? Yes. The pond was Lausanne's launch site for the Franco-Swiss "Nature pour tous" project, supported by the INTERREG 2010-2013 programme. As a result, a path suited to people with reduced mobility links the pond with Chalet-à-Gobet over 1,400 m. When should you visit? Late spring to early autumn is best, when amphibians, dragonflies and birds are active. Mornings are quieter and better for wildlife watching. In winter the area can be snowy and feels like a high-altitude village walk. Bring sturdy shoes, as shoreline paths can be damp. Frequently asked questions Can you swim in the pond? No. It is a nature reserve that protects amphibians, dragonflies and birds. It is meant for walking and observation. How long does the loop take? The path around the water is about a kilometre, so an unhurried circuit takes a little over half an hour, including stops at the bird screen. Is it suitable for wheelchairs or limited mobility? Yes. The 1,400 m route between the pond and Chalet-à-Gobet is adapted for reduced mobility, and two disabled parking spaces are provided. Is it the same as Lac de Sauvabelin? No. Sauvabelin is a larger, separate lake in northern Lausanne. Bressonne is a smaller reserve pond in the hills near Chalet-à-Gobet. Where do you park? In the car park east of the pond, along Route des Paysans.

Ägerisee

Oberägeri

Ägerisee (Lake Aegeri) is a glacial lake in the Swiss canton of Zug, set in the Ägerital valley beside the village of Oberägeri. It sits at roughly 724 m above sea level and covers 7.3 km², about 5 km long and 2 km wide. The deepest point reaches 83 m, with an average depth near 49 m. Two municipalities share the shoreline: Oberägeri and Unterägeri. What is the lake like? Glacial erosion carved the basin. The Hüribach stream feeds the lake and the Lorze river drains it. Since 1992 the water has also served as a reservoir. Since 1798 the lake has belonged jointly to the two shore communities. What can you do at Ägerisee? Swimming is the main summer draw. The Lido in Unterägeri offers a sandy beach, water slides and diving platforms. Sailing and angling are also possible. Excursion boats have run on the lake since 1890, and a cruise pairs easily with a hike or a bike ride. An easy walking route follows the shore for about two hours. It starts at the campsite in Unterägeri, crosses a former bog that is now a nature reserve, and ends at the Morgarten bus stop. A tougher option listed on trail portals climbs from Oberägeri to the Gottschalkenberg ridge (about 15.6 km, around 5 hours, medium difficulty). In summer much of the lakeside path lies in shade. Campsites on the shore give direct access to bathing spots. What is the history behind the lake? The Morgarten area at the southern end of the lake is linked to the Battle of Morgarten on 15 November 1315. Tradition says a Swiss Confederate force defeated the army of Duke Leopold I of Habsburg here. A memorial and an information centre recall the event today, and a themed trail has seven stations. How do you get there? Buses run from Zug to Unterägeri and Oberägeri and stop close to the water. Zurich is under an hour away, so the lake works well as a day trip. The Unterägeri campsite is a convenient starting point for the walking loop. When should you go? June to August is best for swimming. In spring and autumn the lake suits walkers and cyclists, and the paths around the water are quieter. Boat services follow a seasonal timetable, so check it before you travel. Frequently asked questions How big is Ägerisee? It covers 7.3 km², about 5 km in length and 2 km in width, with a maximum depth of 83 m. Can you swim here? Yes. The Unterägeri Lido is the most convenient spot, and the lakeside campsites also have bathing access. Can you walk around the lake? Yes. The easy route from Unterägeri to the Morgarten bus stop takes about two hours and crosses a protected former bog. Do boats run on the lake? Yes. Scheduled excursion cruises operate, and tourist shipping has existed since 1890.

Schwarzsee

Jaun

Schwarzsee (French: Lac Noir) is a small mountain lake in the canton of Fribourg, Switzerland, set in the Fribourg Prealps at roughly 1,050 m above sea level. It covers 0.47 km², yet the scenery is dramatic: the Schwyberg ridge rises to the west, Les Reccardets and the Spitzflue to the south, and Kaiseregg dominates the skyline. The coordinates place it in the German-speaking part of the canton, near Jaun and Plaffeien. What is there to see at Schwarzsee? The lake itself, framed by steep slopes, is the star. An easy walking loop of about 4 km circles the shore and passes the "Dragon of Lac Noir", an iron sculpture standing on a rock about 20 m tall. The path suits families and casual walkers. Why is it called the Black Lake? The name means exactly that. In earlier times the sulphurous water was used for therapeutic baths, and the area still carries the name Schwarzsee Bad as a reminder of those spa days. Can you swim here? Yes, in summer. The beach near Gypsera is a family favourite, and a second one, Staldenmotta, is about a 10-minute walk away. Being an alpine lake, the water stays cool, so expect a refreshing dip rather than a warm bath. Which hikes start nearby? Most routes begin at the Schwarzsee, Gypsera bus stop. The big objective is Kaiseregg (2,185 m). According to the Swiss Alpine Club, the mountain route climbs well over 1,000 m, takes several hours and runs via Golmly and Euschelspass before descending towards Schwarzsee Bad. If you prefer something gentler, the ridge walk along the Schwyberg is a good alternative. When should you go? Summer: lakeshore walks, beaches and mountain hikes. Winter: skiing and snowboarding on the Gypsera slope, run by Kaisereggbahnen Schwarzsee AG; the season usually lasts from December to March. Spring and autumn: quieter days for a short stroll, though higher trails can still hold snow. How do you get there? The easiest approach from Fribourg is via Plaffeien. Public transport serves the lake, and the Gypsera stop is the trailhead for most walks. Car parks are close to the water but fill up quickly on sunny weekends. Frequently asked questions Is Schwarzsee the same as Lac Noir? Yes. Schwarzsee is the German name and Lac Noir the French one, reflecting the language border in the canton. How long does the lake loop take? The circuit is about 4 km and usually takes under an hour and a half at a relaxed pace, including photo stops. Is this the Schwarzsee near Zermatt? No. The name is common in the Alps. This lake lies in Fribourg; the Schwarzsee below the Matterhorn is a different place entirely. Is there a ski area? Yes, a small family-oriented resort with the Gypsera surface lift, open in the winter season.

Bachalpsee

Grindelwald

Bachalpsee is an alpine lake above Grindelwald in the Bernese Oberland, Switzerland, and one of the region's most photographed hiking goals. It sits at 2,265 m (7,431 ft), just beyond the First ridge, and covers roughly 8 hectares. On a windless day its surface mirrors the big peaks of the Bernese Alps. What makes Bachalpsee special? A natural dam divides the lake into two basins, and the smaller one lies about 6 m (20 ft) lower. No forest surrounds it, only pasture and rock, so the views open in every direction. You will also see it called Bachsee. It is known as a mirror lake. When the water is still, it reflects the Wetterhorn, Schreckhorn, Finsteraarhorn and the Grindelwald glacier. That reflection is the image that made the lake an icon of the area. How do you get to Bachalpsee? The route starts in Grindelwald. Ride the First gondola to the top station, then follow the trail towards the lake. It is about 3 km one way and takes 50 to 60 minutes on foot. The climb is moderate, no climbing gear is needed, and sturdy hiking shoes are enough. Return the same way, or extend the day with other trails around First. Plan your descent around the last gondola down to the valley, and check the timetable when you buy your ticket. When should you visit? The trail is easiest from early summer to autumn, once the snow has gone. Early in the season, patches of snow and ice can still cover the path, so poles or microspikes help. Reflections are best early in the morning and at dusk, when the water is calm. During the day wind often ripples the surface and the path fills up. For quiet and good photos, take the first gondola up. What should you bring? Weather changes fast above 2,200 m, even if Grindelwald is sunny. Pack a windproof layer, a hat, sunscreen and water. There is little food available at the lake, so carry snacks or buy supplies at the First station. Frequently asked questions How long is the walk from First to Bachalpsee? About 50 to 60 minutes each way, so just under two hours round trip without long stops. How high is the lake? 2,265 m above sea level, roughly 1,000 m higher than Grindelwald. When are the mountain reflections best? Early morning and dusk, when there is no wind and the surface is smooth. Is the hike difficult? No. It is a mountain walk with a moderate gradient, though leftover snow can make it slippery in early summer.

Greifensee

Aesch

Greifensee is a lake in the canton of Zurich, in the Zürcher Oberland. Aesch, a locality in the municipality of Maur on the western shore, is one of several places from which you can reach the water. It is the canton's second-largest lake and a long-standing weekend escape for people living in the Zurich area. How big is Greifensee? The lake covers about 8.5 km², stretches roughly 6 km in length and reaches 1.6 km at its widest. The shoreline measures nearly 17 km. Maximum depth is about 32 m, with an average of around 17 to 18 m. The municipalities of Greifensee, Uster, Maur, Schwerzenbach and Fällanden border the water, and the river Glatt flows out of it. What will you see? Reed belts and wet meadows line much of the shore. These habitats have been protected since 1941, and the lake serves as a refuge for waterfowl and migrating birds. In protected zones, entering or paddling into the reeds is prohibited, and in places you must stay on marked paths, so binoculars are more useful here than a kayak. A scheduled boat runs all year between Maur and Uster. From spring to autumn there are round-the-lake cruises plus nostalgic trips on the steamship "Greif", built in 1895 and described as the oldest steamship in Switzerland. The Maur to Uster and back round trip takes about 1.5 hours. How can you spend an active day here? A walking and cycling path circles the lake. Sources give its length as 18 to 20 km, depending on the route variant. You can do it on foot, by bike or on inline skates. A popular stretch links Schwerzenbach, Fällanden and the Maur landing stage, and buses from Maur or Fällanden let you cut the trip short. In summer several official lido areas are open, and many shoreline spots are easy to reach. Divers also use the lake, for instance near Maur harbour. How do you get there? From Zurich, take the S-Bahn to Schwerzenbach, Uster or Greifensee; the shore is only minutes from each station. Buses serve Maur and Aesch, including connections from Forch. The simplest plan is a loop that ends with a boat or bus ride back. When should you go? Late spring to early autumn is best: the lidos and cruises operate and the path is dry. For birdwatching, go early in the morning outside the swimming season. Frequently asked questions Can you walk all the way around Greifensee? Yes. The path is roughly 18 to 20 km, so it makes a full-day outing. You can shorten it by taking a bus from Maur or Fällanden. Can you swim in Greifensee? Yes, there are official lidos and open access points. Swimming and landing are prohibited in the reed zones. Is there a boat service? Yes, year-round between Maur and Uster. Sightseeing cruises, including the steamship "Greif", are added from spring to autumn. Is the lake protected? Yes. The reserve covers the reed beds and meadows, and protection dates from 1941. Keep to the marked paths.

Lake Biel

Lake Bienne (BE)

Bielersee (French: Lac de Bienne, also Lake Biel or Lake Bienne) is a lake in western Switzerland, resting below the Jura ridges between the cantons of Bern and Neuchâtel. With Lake Neuchâtel and Lake Murten it forms the Three Lakes Land, and the city of Biel/Bienne on its shore blends German and French culture. Where is Lake Biel and what sets it apart? The lake covers roughly 39 km² and reaches about 74 m at its deepest. The northern shore climbs steeply into the Jura; the southern shore is flat and opens onto the farmland of the Seeland. The language border runs through the area, so towns carry two names: Twann/Douanne, Ligerz/Gléresse, Erlach/Cerlier. What can you see? St. Peter's Island (St. Petersinsel) – a wooded, vine-covered peninsula with a former monastery now serving as a restaurant and inn. Jean-Jacques Rousseau stayed here for several weeks in 1765 and later called it one of the happiest periods of his life. The northern wine shore – Twann, Ligerz and La Neuveville are winegrowers' villages of stone houses, planted mainly with chasselas and pinot noir. A funicular from Ligerz climbs to Prägelz and a lake viewpoint. Pile-dwelling sites – the Sutz-Lattrigen shoreline preserves stilt-house remains from the Stone and Bronze Ages, part of the UNESCO Prehistoric Pile Dwellings around the Alps. Biel/Bienne – a watchmaking city with an old town and a lakefront promenade. Erlach (Cerlier) – a medieval town with a hilltop castle, and the usual starting point for the island. How do you get there? Take a train to Biel/Bienne, which has direct services from Bern, Zurich and Lausanne. The railway follows the northern shore and stops at Twann, Ligerz and La Neuveville. Boats to St. Peter's Island leave from Biel and Erlach and are run by the BLS shipping company. You can also walk or cycle from Erlach along the Heidenweg causeway. What to do on Lake Biel Boat trips link most lakeside towns through the summer season. The wine trail between Biel and La Neuveville runs about 15 km through vineyards. Cyclists can follow the shore paths and the Aare canal. In summer, public lidos at Biel, Tüscherz and Erlach, plus sailing and paddleboarding, draw crowds. When should you go? June to September suits swimming and boat trips. In September and October the grape harvest brings wine festivals to the villages. Winter is quiet, and fog often sits over the water, but on clear days the ride up Chasseral (about 1,600 m) rewards you with views of the lake and the Alps. Frequently asked questions Is Bielersee the same as Biel? No. Bielersee is the lake; Biel/Bienne is the city on its northeastern shore. Can you swim in the lake? Yes. The water is pleasant in summer and several towns operate official beaches and lidos. How do you reach St. Peter's Island? By boat from Biel or Erlach, or on foot or by bike from Erlach, though access along the causeway depends on the water level. Is the local wine worth trying? Yes. Vineyards on the northern shore produce white chasselas and red pinot noir, and many cellars in Twann and Ligerz welcome visitors.

Rotsee

Ebikon

Rotsee in Ebikon is a long, narrow lake on the northern edge of Lucerne, in the canton of Lucerne in central Switzerland. It measures roughly 2.5 km in length and about 250 m in width, with a maximum depth of around 16 m. Its sheltered, straight stretch of water has made it one of the most respected natural rowing courses in the world. The shoreline is shared by the city of Lucerne and the municipality of Ebikon. What will you see at Rotsee? A calm surface framed by wooded slopes and meadows, and in season, crews gliding past in eights and fours. The lake hosts top-level competition, and the annual Lucerne Regatta is part of the World Rowing World Cup circuit. Boathouses and regatta facilities line the water, so on an ordinary day you may well catch national squads in training. Can you walk around the lake? Yes. A path circles the lake, and the local tourist board puts the walk at around an hour. It is easy and mostly flat, which suits families or a short outing after a day in Lucerne. During regatta days some stretches of shore get crowded, and access to certain sections can be restricted. Where can you swim? Swimming is allowed in just one place, the Rotsee-Badi bathing area. A restaurant there operates seasonally, from May to the end of October. Stay out of the water elsewhere, since the rest of the lake is reserved for rowers. How do you get to Rotsee? From Lucerne, take local public transport or a bus towards Ebikon. The area near the regatta start is close to the Ebikon, Falken stop. The trip from central Lucerne is short, so the lake fits easily into a full day in the city. Plan on walking the last stretch to the shore. When is the best time to visit? Late spring, summer and early autumn work best, when the bathing area is open and rowers are on the water. To watch races, check the Lucerne Regatta calendar, which usually runs in summer. Mornings bring the stillest water and the best light for photos. FAQ How long is Rotsee? About 2.5 km long and 250 m wide. Sources quote slightly different figures, so treat them as approximate. Can you swim in Rotsee? Yes, but only at the Rotsee-Badi. The rest of the lake is for rowing. How long does the walk around the lake take? Around one hour at a relaxed pace on an easy path. Is Rotsee in Lucerne or Ebikon? It lies on the border of the city of Lucerne and the municipality of Ebikon, so you can approach it from either side.

Lungerersee

Lungern

Lungerersee (Lake Lungern) is a lake beside the village of Lungern in the canton of Obwalden, central Switzerland. It sits below the Brünig Pass on the route between Lucerne and Interlaken, and for a century it has doubled as a scenic spot and a reservoir for hydropower. What kind of lake is it? The lake covers roughly 2 km², stretches about 2 km from end to end and reaches a depth of around 68 m. Its surface lies near 688 m above sea level. The Sarner Aa river carries its water on through the Sarnersee and into Lake Lucerne. The lake takes its name from the town of Lungern on its shore. Why does the water level change? The lake has an unusual engineering past. In 1836 a man-made drainage tunnel was used to lower the water, freeing up farmland for a commune that had little of it. Streams running into the lake then cut steps into the newly exposed shoreline and eroded fields. In 1921, when the Lungernsee power station was built, the lake was dammed back up and the old tunnel became a pressure tunnel. Today the level rises and falls over the year, so the shoreline looks different depending on the season. What can you do here? Walk or jog around the lake. Obwalden Tourismus describes a loop of about 9.8 km, mostly flat, on gravel roads and paths. Take an easy hike with a waterfall. Komoot lists a short, easy circuit of about 5.5 km that passes the Dundelbach waterfall. Swim and use the water. The lake is used for swimming, fishing and sailing. It is an alpine reservoir, so expect cooler water than in lowland lakes, with the best chances in midsummer. Take photos. The green-tinted water against the valley slopes looks good from the Lungern side and from Kaiserstuhl. How do you get there? Trains on the Brünig line stop in Lungern, close to the lake. By car you can drive into the village or park near Kaiserstuhl, where the walk along the shore begins. Lungern lies on the road from Lucerne through Sarnen towards Brienz and Interlaken, so the lake slots easily into a drive across central Switzerland. When should you visit? Summer and early autumn suit swimming and walking best. Spring and autumn bring quieter paths and often clearer views of the surrounding peaks. In winter the water level can sit noticeably lower, exposing more of the banks. Frequently asked questions Can you swim in Lungerersee? Yes, the lake has swimming spots, and sailors and anglers use it too. Water in an alpine reservoir tends to be cooler than in lowland lakes. How long is the walk around the lake? The loop is about 9.8 km and mostly flat, so it usually takes a few hours at an easy pace. A shorter version past the Dundelbach waterfall is around 5.5 km. Can you reach it without a car? Yes. Lungern has a station on the Brünig line, and the lake is right next to the village. Why does the water level vary? The lake serves a hydropower plant. It was dammed in 1921, and the level shifts with water use.

Lake Brienz

Lake Brienz

Lake Brienz (Brienzersee) lies in the Swiss canton of Bern, in the Bernese Oberland, just north of the main Alpine ridge. A long, narrow turquoise lake, it is one of the two lakes that frame Interlaken. Do not confuse it with the village of Brienz on its shore, or with Brienz in Graubünden. How big is Lake Brienz? The lake is about 14 km long and 2.8 km wide, covering roughly 29.8 km². Its surface sits at around 564 m above sea level. Maximum depth is about 260 m, with an average of 173 m according to Wikipedia and a water volume near 5.2 km³. The catchment area exceeds 1,100 km². Where does the water come from? The Aare enters at the eastern end and leaves at the western end, continuing through Interlaken towards Lake Thun. The Lütschine is the second major inflow, and the Giessbach stream drops into the lake from the slopes below the Faulhorn. The narrow Bödeli strip of land separates Brienzersee from Lake Thun. What can you see around Brienzersee? Giessbach Falls – a cascade on the south shore near Iseltwald, visible from a boat or along walking paths. Brienz village – on the northern shore at the eastern end, beneath the Brienzer Rothorn. Iseltwald – a small south-shore village suited to a short lakeside stroll. Boat trips – regular passenger boats operate on the lake in summer. When is the best time to visit? Boat rides and swimming work best from late spring to early autumn. The water stays cold even in summer because alpine rivers feed the lake. During high-water periods (as in 2012) boat traffic can be restricted, so check the current timetable after heavy rain. How do you get there? The easiest base is Interlaken, between the two lakes. From there, trains and the road along the north shore lead to Brienz. To reach Giessbach and Iseltwald on the south shore, take a boat or drive. Frequently asked questions How deep is Lake Brienz? About 260 m at its deepest point. How does Lake Brienz differ from Lake Thun? They are separate lakes on either side of Interlaken. Brienz is deeper and less built-up along its shores, while Thun lies on the western side of the Bödeli. Can you swim in Lake Brienz? Yes, in summer, but the water is cold. Check local warnings first, especially after rainfall. Where are the Giessbach Falls? On the lake's south shore near Iseltwald, where the Giessbach stream drops into the lake.

Lake Lucerne

Ennetbürgen

Lake Lucerne (German: Vierwaldstättersee, Polish: Jezioro Czterech Kantonów) at Ennetbürgen is a bay of one of Switzerland's best-known lakes. The village sits in the canton of Nidwalden on the southern shore, below the Bürgenstock massif. What is Lake Lucerne? A lake in central Switzerland covering roughly 114 km², with a shoreline of 115 km. It ranks fourth among the country's lakes by area. The deepest point is 214 m in the Uri basin, and the average depth is 117 m. The lake holds about 11.9 billion m³ of water, which is renewed in around 3.4 years. Five cantons share its shores: Uri, Schwyz, Obwalden, Nidwalden and Lucerne. The lake is made up of several linked basins, and the Ennetbürgen area belongs to the Gersau basin, which runs from Brunnen to this village. What can you see in Ennetbürgen? The Engelberger Aa river flows into the lake at Ennetbürgen. In the village centre, near the boat harbour and the post office, you will find the Strandbad Buochs-Ennetbürgen lido. The beach is small, covered in fine gravel, and has showers, changing rooms and sun loungers, with lifeguards on duty. Check hours and facilities locally before you go. Above the water rises the Bürgenstock, a mountain almost completely surrounded by the lake. Its summit lookout is the Hammetschwand, with views over the lake and the surrounding peaks. How do you spend time at the lake? Walk or hike to the Bürgenstock. The trail starts at Postplatz in Ennetbürgen and follows a scenic path from the Schiffländi landing. It is about 8.1 km and takes around 3 hours 10 minutes, passing St. Jost and the Känzeli viewpoint. Take a boat trip. The MS Bürgenstock catamaran runs from Lucerne to Kehrsiten-Bürgenstock, where the Bürgenstock funicular climbs to the resort. Timetables are on lakelucerne.ch. Swim. In summer the Ennetbürgen beach is an easy way to spend a few hours by the water. How do you get there? Ennetbürgen lies across the bay from Lucerne. The simplest route is via Lucerne, then onward by road or by boat on the lake. Check the operators' timetables for exact connections. Frequently asked questions How many cantons border the lake? Five: Uri, Schwyz, Obwalden, Nidwalden and Lucerne. The Polish name, "Lake of the Four Cantons", refers to the four historic cantons at the heart of the early Swiss Confederation. How deep is the lake? Up to 214 m in the Uri basin, 117 m on average. Can you swim in Ennetbürgen? Yes. The Strandbad Buochs-Ennetbürgen lido has showers, changing rooms and lifeguards. How do you walk from Ennetbürgen to the Bürgenstock? The trail from Postplatz is about 8.1 km and takes roughly 3 hours 10 minutes, via St. Jost and the Känzeli.

Hüttnersee

Wädenswil

Hüttnersee is a small moorland lake at Hütten, part of the municipality of Wädenswil in the Canton of Zurich, right next to the Schwyz border. It sits at roughly 658 m above sea level on the northern slopes of the Höhronen and Rossberg ridge, and it is one of the quietest waters near Lake Zurich. What kind of lake is it? The lake covers about 0.165 km2 and is roughly 13 m deep at its deepest point. Reeds, scrub and boggy ground line the shore, and Swiss press has called it an "enchanted place". The south shore officially belongs to Samstagern, a village in Richterswil, while Hütten itself joined Wädenswil in 2019, which is why sources use both names. Farming shaped the area for centuries. Hütten appears in records from 1270, when dairy farms on cleared land belonged to the barons of Wädenswil. Fertiliser run-off from surrounding fields later harmed the water, so the lake now needs artificial aeration. Can you swim here? Yes. A free bathing area on the shore has a wooden pool for non-swimmers, a playground, a sandpit and two pontoons. Entry and parking cost nothing. No lifeguard is on duty, so swimming is at your own risk. A kiosk and a seasonal restaurant operate in summer, and a small farm-style inn on the shore serves home-made food. What are the rules? Most of the shoreline has been protected since 1945, and building and motorboats are banned. Rare plants and vulnerable birds live here, so keep to marked paths and leash your dog where signs ask. How do you get there, and what is nearby? Take a train to Samstagern station and follow the signs to the lake. If you drive, use the free car park by the bathing area. The classic hike starts in Samstagern, passes the lake and Hütten, climbs the Rossberg (1,011 m) and descends to Schindellegi-Feusisberg. It is 10.3 km long with about 524 m of ascent, takes around three hours, is graded T1 and is walkable from March to November. From the summit you see the lake, Lake Zurich and, in clear weather, the Black Forest. A shorter alternative is a loop of about 14 km from Samstagern via the Sihl waterfall. When should you visit? Come in summer for swimming, or in late spring and early autumn for dry trails and fewer people. The bathing area is closed in winter, but the shore suits a short walk. Frequently asked questions Is there an entrance fee at Hüttnersee? No. The bathing area and the parking are free. Is there a lifeguard? No. You swim at your own risk. Are motorboats allowed? No. A 1945 regulation bans motorboats and new building along the shore. How do I get there without a car? Take the train to Samstagern and walk along the signed route to the lake.

Lake Lugano

Lanzo d'Intelvi

Lake Lugano (Lago di Lugano, also called Ceresio) is a glacial lake straddling the Italy–Switzerland border. From Lanzo d'Intelvi, in the Val d'Intelvi of Como province, Lombardy, you see it from above, from viewpoints high over the water. What is Lake Lugano? The lake sits at roughly 271 m above sea level and covers about 48.7 km², around 63% of it in Switzerland and 37% in Italy. It stretches about 35 km and is at most about 3 km wide. The deepest point, about 288 m, lies in the northern basin; the average depth is around 134 m. The Melide causeway splits the lake into a northern basin (about 27.5 km²) and a southern one (about 21.4 km²), with a bridge letting water and boats pass. The Swiss city of Lugano, the largest in Ticino, sits on its shore. What can you see from Lanzo d'Intelvi? Lanzo lies in the Val d'Intelvi, the valley between lakes Como and Lugano. A short walk from the village leads to the Belvedere, a classic viewpoint over Lake Lugano. Higher up, the Sighignola summit (about 1,300 m) hosts the "Balcone d'Italia", the Balcony of Italy. The panorama takes in the lake and distant peaks, and on clear days Monte Rosa and the Matterhorn. The border runs through the site, so there are two terraces, one flying the Italian flag and one the Swiss. The second was added in 2012 after an unfinished cable car station was demolished. How do you reach Sighignola? A scenic road climbs from Lanzo to the summit. It dates from 1913 and was pushed through by Luigi Vittorio Bertarelli, founder of the Touring Club Italiano. You can park by the La Baita restaurant and follow a marked path for about 20 minutes. Sources give the summit's height variously, from about 1,300 to 1,320 m. When should you go? Clear weather matters most, since the Alpine peaks only show then. Check road conditions to Sighignola before setting out, as weather and seasonal closures can affect access. For the Swiss side of the lake, plan a separate trip, for example to Lugano. Frequently asked questions Is Lake Lugano in Italy or Switzerland? Both. About 63% of its surface is Swiss and 37% Italian. How deep is the lake? Up to about 288 m in the northern basin, and about 134 m on average. Where is the best Italian-side view of the lake? The Belvedere in Lanzo d'Intelvi and the Balcone d'Italia on Sighignola. Is the walk to Sighignola long? The road gets you close; from the La Baita car park a marked path takes about 20 minutes.

Lake Zug

Zug

Lake Zug (Zugersee) at the town of Zug sits in central Switzerland, between Lake Lucerne and Lake Zurich. The lake covers roughly 38 km², runs about 14 km from end to end and reaches a depth of 198 m. Three cantons share its shores: Zug, Schwyz and Lucerne. What is the lake like? The long basin stretches from Arth in the south to the Cham–Zug bay in the north. A wooded peninsula called Chiemen splits it in two. The northern Untersee is broad and shallow, while the southern Obersee is deeper and framed by hills. Most of the shoreline belongs to canton Zug, the south to Schwyz, and a small share near Chiemen to Lucerne. The town of Zug lies on the northeast shore, with Arth at the far southern end. What can you see here? The lakeside promenade in Zug is the easiest place to start, a few minutes' walk from the old town. On clear days the mountains above the southern shore come into view, including the Rigi massif rising over Arth. The Lorze river flows through the north of the lake: it enters west of Zug and leaves again near Cham. How do you get out on the water? Boat trips run under Zugersee Schifffahrt. The flagship is the MS Zug, built in 2003, and the MS Rigi from 1992 is also in service. A round-the-lake cruise links the towns on all sides of the shore. In summer, shoreline walks, cycling and swimming at designated spots round out a visit. How do you get there? Zug is a rail hub on the Zurich–Lucerne line, so trains from both cities arrive without changes. The boat landing is close to the station, and you do not need a car to explore the centre and waterfront. When should you visit? Late spring, summer and early autumn are best, when boats run frequently and the weather is warm. Outside the season, services are thinner, so check the timetable before you travel. FAQ How big is Lake Zug? About 38.4 km² in area and roughly 14 km long, with a maximum depth of 198 m and a mean depth of around 83 m. Which cantons border the lake? Zug, Schwyz and Lucerne. Canton Zug holds the largest share of the water. Can you cruise around the lake? Yes. Zugersee Schifffahrt operates a round-the-lake cruise as well as services between shore towns. Is Zug a lake or a town? Both. The name belongs to the cantonal capital and to the lake it sits on. This description covers the lake.

Lake Thun

Sigriswil

Lake Thun (Thunersee) is one of the largest lakes in the Bernese Oberland, stretching between the town of Thun and Interlaken. This entry covers the lake itself, on whose northern shore the municipality of Sigriswil sits. The lake covers roughly 48 km², runs about 17 to 18 km in length, reaches a depth of around 217 m, and lies near 560 m above sea level. Where is the lake and what feeds it? Thunersee sits in the canton of Bern, about 30 km southeast of the Swiss capital. The main inflow is the Aare, which enters from the Interlaken side and leaves again at Thun. The Kander and the Lombach add further water. Thun, known as the gateway to the Bernese Oberland, marks the western end, Interlaken the eastern one, and smaller villages line the shores in between. What can you see around Thunersee? Castles define the shoreline. Oberhofen Castle on the northern shore grew around a heavy defensive tower dating from the early 13th century, and its gardens reward a stroll. Spiez Castle crowns a promontory on the southern shore, and the town is known for vineyards on some of the highest-lying vine slopes north of the Alps. In Thun, a castle of its own towers over the old town. Sigriswil lies higher up, on a terrace above the water. Its viewpoints look out over the lake and the Bernese Alps. The Justistal valley, where a local cheese-sharing festival takes place in autumn, offers hiking trails. How do you explore the lake? By boat is easiest. Services link Thun, Spiez, Oberhofen, Interlaken and other landings, so you can hop off at a castle and catch a later sailing. Railways and roads follow the shores, and hiking and cycling routes let you walk or ride the lake in stages. In summer you can swim at the beaches and lidos, though the water stays cool. When should you visit? Late spring, summer and early autumn are best, when boats run a full timetable and the mountain views are clearest. In September you may catch the cheese festival in Justistal. Winter sailings are reduced and some attractions close for the season. Frequently asked questions How deep is Lake Thun? The deepest point is about 217 m, and the surface area is about 48 km². Is Thunersee the same as the town of Thun? No. Thun is the town at the western end of the lake, while Thunersee is the body of water that reaches all the way to Interlaken. Which castles are worth visiting on the lake? Visitors usually pick Oberhofen on the north shore, Spiez on the south shore and the castle in Thun. How do you get to Sigriswil? The municipality lies on the northern shore and can be reached by road from Thun. From there, local hiking routes and viewpoints are close by.

Lake Constance

Lake Constance (German: Bodensee) sits at the foot of the Alps and is shared by three countries: Germany, Austria and Switzerland. The Swiss shore, spread across the cantons of Thurgau and St. Gallen, offers a calmer lakeside break with harbour promenades, medieval towns, castles and a cycling route that hugs the water. How big is Lake Constance? The lake covers roughly 536 km², stretches up to 63 km in length and 14 km in width, and reaches a depth of around 250 m. Its surface lies about 395 m above sea level. It has two basins: the broad Obersee and the smaller Untersee in the west, linked by a stretch of the Rhine called the Seerhein. The Rhine flows in near Bregenz and leaves through the Untersee. The lake also supplies drinking water to about 4.5 million people. What is there to see on the Swiss side? Romanshorn is the main Swiss port on the lake, with a pleasant harbour promenade and ship landing. Rorschach lies at the lake's southernmost point and was once one of its key harbours. Arbon has a medieval old town and a lakeside castle, extended between 1510 and 1518 under Bishop Hugo von Hohenlandenberg, with the Saurer Museum close by. Steckborn and Ermatingen mark the stretch of the Untersee with the densest cluster of castles and fortified houses. Gottlieben, on the Seerhein, is known for one of the prettiest village squares in Switzerland. Kreuzlingen is the largest Swiss town on the lake and borders German Konstanz directly. Across the border, the island of Mainau, nicknamed the Island of Flowers, shows over half a million blooming plants each year. How do you explore the lake? By boat, ideally. Rhine and Untersee services run under the operator URh, and in season ships link ports in all three countries. The alternative is the Bodensee cycle path around the lake; the Swiss stage runs from Rorschach through Arbon and Romanshorn to Kreuzlingen. It is mostly flat and works well for families. When should you go? Summer is swimming season, with lakeside pools and beaches at places such as Altnau, Arbon and Staad. Spring and early autumn bring fewer crowds and comfortable cycling weather. Timetables and fares change every season, so check the operators' websites before you plan a cruise. Frequently asked questions Which countries share Lake Constance? Germany, Austria and Switzerland. There is no single formally agreed border across the whole water surface. How deep is it? About 250 m at the maximum; sources quote values between 251 and 254 m. Can you cycle all the way around? Yes. The Bodensee cycle route circles the lake through all three countries, and its Swiss section connects Rorschach, Arbon, Romanshorn and Kreuzlingen. Which Swiss town works best for a day trip? Choose Steckborn or Ermatingen for castles and quiet lanes, Romanshorn for the harbour and promenade, and Arbon for a medieval old town.

Lake Neuchâtel

Lac de Neuchâtel (NE)

Lake Neuchâtel (Lac de Neuchâtel) is the largest lake lying entirely within Switzerland, stretching along the foot of the Jura mountains in the west of the country. Germans call it the Neuenburgersee. It anchors the Jura and Three Lakes region (Trois-Lacs), with vineyard slopes, lakeside towns, beaches and nature reserves along its shores. How big is Lake Neuchâtel? The surface covers roughly 218 km². The lake runs about 38 km in length and up to around 8 km in width. Its greatest depth is about 152–153 m, and it holds some 14 cubic kilometres of water. On a clear day the Alps line up along the far horizon. Which cantons share the shoreline? Four cantons touch the water. The canton of Neuchâtel has the longest stretch at around 86 km, followed by Vaud (about 74 km) and Fribourg (about 53 km). Bern reaches the lake only at the north-eastern tip, in the Seeland area. French is spoken on most shores, with German heard near the language border. What is there to see? Neuchâtel – the cantonal capital on the north shore, with its castle and a lakeside old town. Yverdon-les-Bains – the town at the southern end, known for its thermal baths. Estavayer-le-Lac – a medieval old town on the Fribourg shore, with Chenaux Castle, a marina and two beaches. Grande Cariçaie – Switzerland's biggest reed area, a mix of marshes, shallows and woodland along the south shore just east of Yverdon. The Pro Natura centre at Champ-Pittet is the usual starting point. Vineyards – the Jura-facing slopes on the north shore are planted with vines. What are the Three Lakes? Lake Neuchâtel, Lake Biel (Bienne) and Lake Murten (Morat) are linked by canals: the Thielle joins Neuchâtel to Biel, and the Broye connects it with Murten. Boat cruises can take you between the three lakes. The area is known as Trois-Lacs in French and Drei-Seen-Land in German, and has its own walking route, the Chemin des Trois-Lacs. Stage one, from Yverdon to Estavayer, is about 22 km and takes around 5.5 hours, passing Champ-Pittet, the reed reserve, Yvonand and Cheyres. How can you spend time at the lake? In summer people swim, sail, take boat trips and stroll along the promenades. Outside the season, cycling or walking along the shore, visiting wine growers and birdwatching in the Grande Cariçaie reserve all work well. From the north shore it is a short trip up into the Jura, where trails offer views back down over the water. How do you get there? Neuchâtel, Yverdon-les-Bains and Estavayer-le-Lac all have railway stations, with regional and long-distance trains from Bern, Lausanne and Zurich. Passenger boats serve harbours on Lake Neuchâtel, Lake Biel and Lake Murten, and cycle routes run around the shoreline. Frequently asked questions Is Neuchâtel a lake or a city? Both. The lake gave its name to the canton and its capital, which sits on the north shore. How many cantons border the lake? Four: Neuchâtel, Vaud, Fribourg and Bern, the last only along a short stretch. Is it the biggest lake in Switzerland? It is the largest lake located wholly inside Switzerland. Lake Geneva and Lake Constance are bigger but are shared with neighbouring countries. Where is the best place for nature? The Grande Cariçaie reserve on the south shore, near Yverdon-les-Bains and Estavayer-le-Lac.

Lac de Champex

Som-la-Proz

Lac de Champex is a small mountain lake in the municipality of Orsières, canton of Valais, Switzerland, beside the village of Champex-Lac (near Som-la-Proz). It covers about 17 hectares and lies at roughly 1,470 m above sea level, ringed by larch and spruce forest below the Mont Blanc massif. It is one of the best-loved alpine lakes in Lower Valais. How did the lake form? An old moraine left by the Arpette glacier dammed the valley and created the basin. A stream from the Val d'Arpette feeds it today. At the northern end, marshland and wet meadows form a protected nature reserve of national importance. How do you get to Champex-Lac? A winding cantonal road climbs about 7 km from Orsières, gaining around 600 m in height. Cars, buses and cyclists all use it, and road cyclists count it as a classic ascent. From the village centre the shore is a few minutes on foot. What is there to do at the lake? Lakeside walk. An easy, level loop with mountain views mirrored in the water, doable in under an hour. Rowing and pedal boats. In season you can hire a rowing boat or pedalo right at the shore. Flore-Alpe alpine garden. It holds more than 4,000 plant species from the Alps and other mountain ranges. La Breya chairlift. It takes you up to a panoramic viewpoint over the Valais Alps. Hiking. Trails start from the lake into the Val d'Arpette, to the Relais d'Arpette hut (an easy walk, famous for its local blueberry tart) and on to the Cabane d'Orny. The village is also a stage of the Tour du Mont Blanc. Bisse de Champex. A route along a traditional Valais irrigation channel. Walks with St. Bernard dogs. Offered as guided outings. When should you visit? Summer suits walking, boating and hiking, with most paths open from June to September. In hard frosts the surface can freeze over, and the area then offers snowshoe trails and cross-country skiing. Frequently asked questions How big is the lake? About 17 ha, so a full circuit takes little time. Can you walk all the way around it? Yes. The loop is easy and well marked, and it passes the marshes at the northern end. Can you rent a boat? In season, yes: rowing boats and pedal boats are available by the shore. Check hours and prices locally. Is Champex-Lac on the Tour du Mont Blanc? Yes, the village is one of the stages of the popular circuit around the Mont Blanc massif.

Lac de Sauvabelin

Lozanna

Lac de Sauvabelin is a small artificial lake set in the forest above Lausanne, in the canton of Vaud. It has been a favourite spot for Sunday outings for well over a century, and since 2003 a wooden lookout, the Tour de Sauvabelin, has stood nearby. How did the lake come about? In 1887 the Société de développement de Lausanne proposed creating a lake in the Sauvabelin woods to widen the leisure options for locals and a growing number of foreign visitors. The city authorities backed the plan and the lake was finished a year later. It was built for recreation: people rowed on it in summer and skated on it in winter. A restaurant opened beside it three years after the lake itself. The city calls the lake the main attraction of the whole Sauvabelin area. What is there to see? Forest paths run around the water, so a stroll round the lake is short and needs no preparation. Families, school groups and visitors have gathered here since the 19th century. The standout feature is the Tour de Sauvabelin, a few minutes' walk from the restaurant. It rises more than 35 metres and has 302 steps winding up in a spiral. The structure is solid Douglas fir taken from Lausanne's own forests. The idea was put to the municipal council in 1994 and the tower was completed in 2003. It cost 1.19 million Swiss francs, with much of the money coming from donors who each bought one or more steps. From the top you get a 360-degree view. In 2014 more than 90,000 people climbed it. How do you get there? Take tl bus line 16 to the Signal or Lac de Sauvabelin stop. From there it is roughly five minutes on foot to the lakeside restaurant. The lake lies at about 46.5375 N, 6.6383 E. Is the tower free, and when is it open? Entry is free. Opening hours change with the season, so check the City of Lausanne or Lausanne Tourisme websites before you go. For safety, 30 people at most may be on the tower at once, and an automatic gate controls access. In strong wind, snow or ice the tower is closed. When should you visit? The lake and woods work in any season, but the tower pays off most on clear days, when the panorama is sharpest. In winter, remember that ice can shut the climb. Frequently asked questions Is Lac de Sauvabelin natural? No. It was created in 1888 on the initiative of Lausanne's development society as a leisure site. How many steps does the Tour de Sauvabelin have? 302, and the tower is more than 35 metres tall. Do I need a ticket for the tower? No, entry is free, but the tower closes in bad weather. How do I get there from central Lausanne? Take tl bus 16 to Signal or Lac de Sauvabelin, then walk about five minutes.

Lac de Joux

Les Charbonnières

Lac de Joux is a Swiss Jura lake whose shore lies beside the village of Les Charbonnières in the canton of Vaud. At roughly 1,004 m above sea level and about 9.5 km², it is the largest lake in Switzerland that sits above the 1,000 m mark. Where is Lac de Joux? The lake fills the Vallée de Joux in the Vaud Jura. The forested Risoux range closes the valley to the northwest, and its crest follows the French border. On the other side rises Mont Tendre (1,679 m). Three municipalities share the shoreline: Le Chenit, L'Abbaye and Le Lieu, and Les Charbonnières belongs to Le Lieu. The whole area falls within the Parc Jurassien Vaudois, a regional nature park. What makes this lake unusual? The River Orbe is its main feeder, and the maximum depth is around 32 m. There is no surface outflow of note. Water drains through fissures in the limestone and resurfaces near the caves at Vallorbe, a link confirmed by tracer studies. What can you do in summer? Water temperatures reach about 18 to 24°C, so swimming is popular, and many of the beaches are free. Steady winds draw windsurfers and kitesurfers. You can also rent kayaks, pedal boats or paddleboards. Walking and cycling routes circle the lake, and several educational trails run through the valley. Anglers fish from the shore and from boats, and in season you can take a cruise aboard a vintage wooden boat. What can you do in winter? In cold winters the lake freezes over and becomes one of the largest natural ice rinks in Switzerland. Skates can be rented in Le Sentier and, on busy weekends, on the shore in the bay of Le Pont. Ice does not form every year, so check the valley tourist office's live update before you go. About 200 km of cross-country trails cover the surrounding area, and snowshoeing and dog sledding are on offer too. When should you visit? For swimming and water sports, come between June and September. For skating and cross-country skiing, aim for January and February during a hard frost. In autumn the shoreline path makes a pleasant walk around the lake. Frequently asked questions Can you swim in Lac de Joux? Yes. Summer water temperatures reach up to 24°C, and the beaches are free to use. Does the lake freeze every winter? Not always. When the ice is thick enough, a natural rink forms. Check with the valley tourist office for current conditions. How big is the lake? It covers about 9.5 km², lies at 1,004 m and reaches roughly 32 m deep. Which sports are popular here? Windsurfing, kitesurfing, paddleboarding, kayaking and water skiing in summer, then skating and cross-country skiing in winter.

Lake Murten

Mont-Vully

Lake Murten (Murtensee, Lac de Morat) at Mont-Vully sits in western Switzerland, straddling the cantons of Fribourg and Vaud. Its northern shore is bounded by the vine-covered hill of Mont Vully. At roughly 22.8 km2, it is the smallest of the three large lakes at the foot of the Jura. It takes its name from the small bilingual town of Murten (Morat) on the southern shore. What can you see around the lake? The scenery is gentle farmland and water, with the Bernese Alps on the horizon. On the north side, Mont Vully is the main draw. From its 653 m summit you can take in Lake Murten, Lake Neuchâtel and Lake Biel together, and on clear days the Jura and the Alps as well. Winegrowing villages line the southern slope, from Môtier through Praz and Lugnorre to Guévaux. The town of Murten, across the water, makes a worthwhile day trip in its own right. What is the Vully wine region like? Vully is a small appellation of about 150 hectares, around 1% of Swiss vineyards. Chasselas is the leading grape and makes up about two thirds of production, with pinot noir in second place. Many local growers welcome visitors in their cellars, so a walk through the vines pairs easily with a tasting. How do you get up Mont Vully? A narrow, winding road climbs to the top from Sugiez or Môtier. You can also walk up through the vineyards on marked paths, some with picnic spots. The flat shoreline around the lake suits cycling, and the area has its own tourist information offices, including one in Salavaux. Can you swim in Lake Murten? Yes. The lake is fairly shallow, so the water warms quickly and is pleasant for swimming from late spring into autumn. There are beaches, and walking and cycling routes follow the shore. When should you visit? Summer is the season for swimming and sailing. September and October bring the grape harvest, when the vineyards on Mont Vully turn golden. Alpine views are sharpest on clear, cooler days. Frequently asked questions Which cantons does Lake Murten lie in? It lies between Fribourg and Vaud, in the Three Lakes region (Drei-Seen-Land). How high is Mont Vully? The hill reaches 653 m above sea level and is a well-known viewpoint. What wine comes from Vully? Mostly chasselas, followed by pinot noir, from about 150 hectares of vines. Can you reach Mont-Vully without a car? Yes. Many stretches can be walked or cycled, and routes from Sugiez and Môtier lead straight up the hill.

Heidsee

Vaz/Obervaz

Heidsee is a small mountain lake at Lenzerheide in the municipality of Vaz/Obervaz, canton of Graubünden, Switzerland. It sits at roughly 1,485 m above sea level between the villages of Valbella and Lenzerheide, and its Romansh name is Igl Lai. With a surface of about 0.41 km², it is easy to walk around in an hour. In summer people swim and paddle here, and in winter the shore becomes a flat walking route. What is the lake like? The water is split into a larger northern basin and a smaller southern one, separated by a causeway. The surrounding high valley turned into a winter sports area during the second half of the 20th century, so the lake sits right in the middle of the resort rather than on its edge. How do you get to Heidsee? The easiest start is the car park by the lake, which is the usual trailhead for the shore loop. You can also walk in from Valbella or Lenzerheide, since both villages are a short distance from the water. The valley is reached by mountain road from Chur, and local transport links the settlements. What can you do here in summer? Walk the shore loop. The circuit is about 3 km, hugs the water and has no significant climbs. It is easy and stroller-friendly, which makes it a favourite with families. Swim. In summer the water warms to above 20°C. Try water sports. A water sports centre rents out windsurfing gear and pedal boats, kayaks, rowing boats and stand-up paddleboards, and runs sailing courses. What about winter? When the lake freezes, flat winter walking routes run along it. One of them, 2.6 km long, links Valbella Canols with Lenzerheide La Riva. Step onto the ice only once it has been cleared and officially opened for use. A cross-country ski trail also follows the shore towards the Luzius meadow in Lenzerheide. When should you visit? Come in midsummer for swimming and boating, when the water is warmest. The loop walk works well from late spring through autumn. For winter walks or skiing, aim for the heart of the season, when the ice is thick and the routes are prepared. Frequently asked questions Can you swim in Heidsee? Yes. The water passes 20°C in summer and a water sports centre operates on the shore. How long is the walk around the lake? About 3 km with almost no elevation gain. The path is easy and suitable for strollers. Is it safe to walk on the ice in winter? Only on ice that has been prepared and opened. The winter route from Valbella Canols to Lenzerheide La Riva is 2.6 km. Where is the lake, and what is its Romansh name? In Vaz/Obervaz, between Valbella and Lenzerheide in Graubünden. In Romansh it is Igl Lai.

Lake Geneva

Féternes

Lake Geneva (Lac Léman) is the largest lake in the Alps and in Western Europe. It sits on the border between Switzerland and France, and its French shore, around Féternes, Évian-les-Bains and Thonon-les-Bains in Haute-Savoie, forms the southern side below the Chablais mountains. How big is Lake Geneva? The surface covers roughly 580 km², of which about 235 km² belongs to France and 345 km² to Switzerland. The lake stretches around 72 km in length and up to 13.8 km across. Its deepest point, about 310 m, lies between Évian and Ouchy (Lausanne); the average depth is around 152 m. It holds about 89 km³ of water, and the surface sits near 372 m above sea level, with the level managed within a narrow band. What is there to see on the French side? The south shore is a string of spa towns and harbours. Évian-les-Bains is known for belle époque villas, terraced gardens and a lakeside promenade. Thonon-les-Bains, the capital of the Chablais, has a port, waterfront paths and a view across to Lausanne and Ouchy. From the slopes above the shore, including the Féternes area, clear days reveal the water and the Swiss hills opposite. To the west lies Yvoire, a medieval village on the water and a favourite stop on day cruises. How do you get there and get around? The French shore is reached by car or bus from Geneva; the train no longer runs between Évian and Saint-Gingolph, so that stretch needs a bus. Boats of the Swiss operator CGN cross the lake: year-round services link Lausanne with Évian (line N1) and with Thonon (N2), and a separate line runs Yvoire to Nyon. Winter timetables are thinner. Excursion cruises also call at Yvoire and Saint-Gingolph, and some 45-minute cruises from Évian show the villas and gardens from the water. When should you visit? Late spring, summer and early autumn suit swimming, sailing and promenade walks, and the full boat timetable runs then. In winter the shore is quiet, snowy Alps frame the view, and fewer sailings operate. Frequently asked questions Is Lake Geneva in France or Switzerland? Both. The north shore with Lausanne, Vevey and Geneva is Swiss; the south shore with Évian and Thonon is French. How deep is it? Up to about 310 m, averaging around 152 m. Can I cross the lake by boat? Yes. CGN boats connect Lausanne with Évian and Thonon, and Yvoire with Nyon. Where should I stay on the French side? Évian-les-Bains and Thonon-les-Bains have the best boat links, harbours and promenades; Féternes offers a quieter base close to both.

lake Inkwil, Paleolithic open-air station / Neolithic and Bronze Age lakeside settlement

Inkwil

Lake Inkwil (Inkwilersee) in Inkwil is a small, shallow lake on the border between the Swiss cantons of Bern and Solothurn. It is one of the places where people built lakeside settlements for thousands of years. The island in the lake belongs to the prehistoric pile-dwelling sites on the UNESCO World Heritage list, and it is also a nature reserve. It suits visitors who like archaeology and quiet water landscapes in the Oberaargau region. Where is Lake Inkwil? The lake lies between the villages of Inkwil (canton of Bern) and Bolken (canton of Solothurn), at roughly 47.199 N, 7.663 E. Its large island is split about equally between the two municipalities, so the archaeological services of both cantons look after it together. The lake is a moraine lake left by the last Ice Age. It is slowly silting up and is barely more than 5 metres deep at its deepest point. What lies beneath the island? Cultural layers and wooden piles from former buildings survive in the island and the lake bed. Archaeologists trace the earliest settlement to the Neolithic, from about 3800 BC. Activity peaked in the Late Bronze Age, around 1000 to 850 BC. Iron Age and Roman-period finds have also turned up. One of the most striking discoveries is a rare Bronze Age wooden sword, recovered during a dive by Bern's underwater archaeologists. Waterlogged mud shuts out oxygen and preserves wood and organic material, which is why such sites reveal far more than dry-land settlements. The site has been part of the UNESCO "Prehistoric Pile Dwellings around the Alps" listing since 2011. Why did the lake make the news? In 2018 divers from Bern's cantonal archaeological service found that beavers had dug tunnels into the island, cutting through prehistoric layers and timbers. Both cantons approved a protective grid around the island, with costs put at about 800,000 Swiss francs. An exhibition notice says the island has been protected from beavers since December 2025. How should you visit? The protected zone covers the whole island and the lake bed next to it, so this is a place to view from the shore, not to explore. Do not expect a reconstructed village or an on-site museum. Information boards and material from the Bern and Solothurn archaeological services give the background. Keep quiet and stay out of the reserve, which is habitat for waterbirds and beavers. Frequently asked questions Is Lake Inkwil in Bern or Solothurn? Both. The lake sits on the cantonal border, and the island is shared by Inkwil (Bern) and Bolken (Solothurn). How old is the settlement? Traces go back to the Neolithic, about 3800 BC. The densest occupation came in the Late Bronze Age, around 1000 to 850 BC. Can you walk onto the island? No. The island is a protected nature reserve and archaeological site, so visitors look at it from the shore. Is the site a UNESCO World Heritage Site? Yes. It is part of the "Prehistoric Pile Dwellings around the Alps" listing, inscribed in 2011.
