Welcome to the Claus bathing lake in Sedrun. The lake is in an amazingly beautiful situation with open views of the surrounding mountains, and the water temperature is very pleasant. On the grassy banks, deckchairs are available free of charge while children can build sand-castles on the beach or paddle their way over to the other shore on a raft. 

Opening hours

The bathing lake and restaurant in Claus Surrein are open from the beginning of June until the end of October, on Monday - Sunday, from 10am – 7pm in fine weather (opening hours may be longer, depending on the weather).


Healthy appetites are well catered for.  Whether you come for lunch or dinner or just a cosy drink with friends and a snack, the Bistro Lag Claus Surrein is the place for you. 

On the sunshine terrace right beside the lake, you can enjoy wholesome hot and cold meals, snacks, crunchy salads, a variety of cakes and ice cream and hot or chilled drinks.

More information


Four-legged friends are welcome at the bathing lake.  However, we ask that you keep your dog on a lead, and dogs are not allowed in the lake. 

Breakable items 

Bringing glass bottles, glasses or other breakable items to the lake is forbidden.
