5 Most Famous Lakes in Switzerland

1. Lake Lucerne

Lake Lucerne

Lake Lucerne is one of the most beautiful and historically important lakes in Switzerland. Surrounded by mountains like Mount Pilatus and Mount Rigi, the lake is famous for its scenic paddle steamer cruises, medieval lakeside towns, and dramatic fjord-like landscape.

The city of Lucerne sits directly on the lake and is home to the iconic Chapel Bridge and Old Town. Lake cruises on Lake Lucerne are fully covered by the Swiss Travel Pass.

• Best for: Scenic cruises, mountain views, Swiss history, Lucerne sightseeing

2. Lake Geneva 

Lake Geneva is the largest lake in Switzerland and stretches from Geneva to Montreux. Known for its elegant waterfront towns, vineyard terraces, and castle views, it is one of the top places to visit in Switzerland.

Highlights around the lake include the UNESCO-listed Lavaux Vineyards, Chillon Castle, and lakeside promenades in Lausanne and Montreux.

• Best for: Castles, vineyards, luxury stays, lakeside towns

3. Lake Brienz 

Lake Brienz is famous for its bright turquoise water created by glacier melt from the Swiss Alps. Located near Interlaken, the lake is surrounded by steep mountains, waterfalls, and scenic boat routes.

One of the biggest attractions here is Giessbach Falls, a multi-step waterfall that flows directly into the lake.

• Best for: Turquoise colour, Giessbach Falls, wood carving, short cruises from Interlaken

4. Lake Thun 

Where Lake Brienz is vivid and narrow, Lake Thun is broad and warmly domestic, a large, open lake with mountain views in every direction and water temperatures that reach 22°C by mid-July, making it the most popular swimming lake in Switzerland. The lakeside promenades at Spiez, Thun, and Interlaken are three of the finest lakeside walks in Switzerland.

The Harder Kulm funicular above Interlaken provides the classic view of both Lake Brienz and Lake Thun simultaneously from above, the iconic two-lakes panorama.

• Best for: Swimming, lakeside walking, watersports, Spiez castle views

5. Lake Zurich 

Lake Zurich is more intimate than Geneva or Lucerne, 40 km long and flanked by gentle hills rather than dramatic peaks, but it is one of the finest urban lakes in Europe. Located in Zurich, the lake is famous for waterfront promenades, cafés, swimming spots, and boat cruises. The public lido (Seebad) culture is seen here with dozens of historic bath houses where Zurichers swim, sunbathe, and jump from wooden platforms directly into the lake, is one of the most pleasantly distinctive aspects of urban Swiss life.

The lake boats here are covered by the Swiss Travel Pass and run to towns including Rapperswil (with its rose gardens and castle) at the far end.

• Best for: City swimming, urban lake walks, cafés with lake views, a day trip to Rapperswil

Alpine Lakes Worth Visiting in Switzerland

6. Lake Oeschinen (Oeschinensee)

Lake Oeschinen is one of the most stunning alpine lakes in Switzerland, known for its turquoise glacial water and dramatic limestone cliffs of the Blüemlisalp massif rising directly above the lake. Located near Kandersteg, it is part of the UNESCO Jungfrau-Aletsch region.

Visitors can reach the lake by cable car, followed by a short hike. Activities include rowing boats, lakeside walks, and panoramic hiking trails.

• Best for: Alpine scenery, hiking, photography, rowing boats

7. Blausee, Kander Valley

Blausee is a small mountain lake famous for its crystal-clear, deep blue water fed by underground glacial springs. Located near Frutigen in the Kander Valley, the lake sits inside a peaceful nature park with forest trails and a glass-bottom boat experience.

The lake is especially popular for families, photography, and relaxing day trips from Interlaken or Kandersteg.

• Best for: Blue water, nature walks, families, glass-bottom boat

8. Lake Constance (Bodensee)

Switzerland’s largest lake by surface area (and shared with Germany and Austria), Lake Constance, sits at the northeastern corner of the country near St. Gallen. Its character is gentler and more Germanic than the Alpine lakes – broad, cultivated shores, apple orchards, and the well-preserved medieval island town of Stein am Rhein nearby. The island of Mainau (German side) and the UNESCO-listed island monastery of St. Gallen are easily reached from the Swiss shore.

• Best for: German-Swiss atmosphere, cycling along the shore, medieval towns, milder scenery

9. Lake Lugano (Lago di Lugano), Ticino

Lake Lugano offers a unique mix of Swiss landscapes and Italian culture. Located in the Italian-speaking Ticino region, the lake is surrounded by palm trees, lakeside cafés, and scenic mountain viewpoints. The city of Lugano on the lake’s north shore combines Swiss efficiency with Italian café culture. Monte San Salvatore provides the finest panoramic view of the lake and the surrounding Italian Alps.

• Best for: Warmth, Mediterranean character, Italian-Swiss fusion culture, swimming in summer

10. Lake Maggiore (partial), Ticino

Lake Maggiore lies partly in Switzerland and partly in Italy, with the Swiss side centred around Locarno and Ascona. The lake is famous for lakeside promenades, island excursions, and beautiful hillside scenery.

It is also the gateway to the scenic Centovalli Railway connecting Switzerland and Italy.

• Best for: Italian culture, island excursions, vine-covered hillsides

11. Sihlsee, Canton Schwyz

Sihlsee is the largest artificial lake in Switzerland and is located near Einsiedeln. Surrounded by rolling hills and countryside, the lake is popular for cycling, windsurfing, and peaceful nature escapes. The combination of Einsiedeln’s baroque monastery and the lake’s pastoral setting is one of the quieter, more genuinely Swiss experiences available within an hour of Zurich.

• Best for: Day trip from Zurich, Einsiedeln monastery, cycling, quiet atmosphere

12. Oeschinensee to Bachalpsee

Bachalpsee is a small alpine lake above Grindelwald, reached via a scenic hike from Grindelwald First. The lake is famous for reflecting the surrounding Alpine peaks like Schreckhorn and Finsteraarhorn. It is best visited in the morning when the water is calm, and the light hits the surrounding peaks directly.

• Best for: Reflection photography, mountain hiking, easy access from Grindelwald First

13. Lake Biel/Bielersee

Lake Biel is one of Switzerland’s most underrated lakes, located near the Jura mountains and the watchmaking region around Biel/Bienne. The peaceful St. Peter’s Island is a major attraction and can be reached by boat. Compared to larger Swiss lakes, Lake Biel offers a quieter and less touristy experience.

• Best for: History, Rousseau connection, peaceful scenery away from tourist circuits

14. Lake Neuchâtel

Lake Neuchâtel is the largest lake located entirely within Switzerland. Found in the French-speaking part of the country, it is known for vineyards, lakeside towns, and regional Swiss wine culture. The city of Neuchâtel offers beautiful old streets, lake views, and easy access to wine regions.

• Best for: Swiss wine country, French-speaking Switzerland, fewer tourists, regional culture

15. Klöntalersee

Klöntalersee is a scenic mountain lake in the Canton of Glarus surrounded by forests and limestone peaks.

The reflections of the Glärnisch massif on the lake make it especially beautiful during calm mornings.

• Best for: Solitude, genuinely off-the-beaten-path, wild alpine scenery

Practical Tips for Visiting Lakes in Switzerland

• Use the Swiss Travel Pass for lake cruises – Most boats on Lake Geneva, Lake Lucerne, Lake Thun, and Lake Brienz are fully covered in the Swiss Pass.
• Swim at designated “Badi” areas – Badi is the public lake swimming zones, which include changing rooms, showers, and safe entry points.
• Visit lakes early in the morning – The calm water of these lakes, before 10 AM, offers the best reflections and photography conditions, especially at Lake Oeschinen and Bachalpsee.
• Combine lakes with mountain excursions – The Swiss lakes are most rewarding when you also engage with the mountains above them. The Gornergrat Railway above Zermatt gives you high-altitude lake views; Mount Pilatus above Lake Lucerne combines a lake cruise with a mountain railway in one circular excursion.
