When we think of Switzerland, we think of snow-capped alps, skiing and cold weather! However, Switzerland offers pristine lakes which are actually warm enough to take a swim in during the hotter months and are perfect for summer getaways.

For those looking to spend their summer away from islands and beaches, Switzerland has some great lakes to swim in while enjoying the stunning scenery around. From the biggest and best-known lakes such as Lake Geneva to breathtaking Alpine lakes, we’ve gathered some of the best lakes in Switzerland to swim in summer!

High up in the alps of Zermatt lies Lake Leisee. At 2,232 meters above sea level, this mountain lake is a real treat in summer. Lake Leisee is fed by the surrounding glaciers that produces amazingly clear water. Despite its altitude, Leisee is not deep and the water warms up in summer, making it a great place to swim. The little stream that flows into the lake is also perfect for children to play in.

There is also a children’s playground, barbeque and picnic areas and a floating raft. With the majestic Matterhorn in the background, swimming in Leisee comes with an amazing view.

Entry is free to Leisi. Click here for more information.




Known as ‘Lag la Cauma’ in the Romansh language, meaning ‘lake siesta’, Lake Cauma is a tranquil lake with turquoise-coloured waters. Lake Cauma is located in Flims in Canton Graubünden and it is not hard to see why it is called The Jewel of Flims. This beautiful lake has been listed as one of the top ten lakes in Switzerland and is probably one of the best lakes in Switzerland to swim in summer.

Lake Cauma is perfect for swimming during the summer with its pleasantly cool water temperatures between 17 to 24 degrees celcius. The lake is surrounded by forest on three sides with a wooded island in the centre of the lake where you can swim to.

The Engadine is known for its lakes. Above all, the Big Four: Lake Sils, Silvaplana, Champfèr and St. Moritz. However, these bigger lakes do not get warm enough for a swim in summer.  However, smaller hill moor lakes such as Lake Staz,  nestled between St. Moritz and Pontresina in the middle of a wide, open clearing in the vast forest of Staz is great for swimming.

With is dark water and shallower banks, Lake Staz is calm and gets all the sunlight it can during the summer months. The water temperature at Lake Staz rises over 20 degrees celcius in summer and is ideal for a refreshing swim. The swampy meadows, which partly surround Lake Staz, give it its unique character. There are two jetties, a children’s playground and a small beach area to relax around the lake, making it an ideal place to unwind and enjoy the mountains around you.

Free entry. More information can be found here.
