Lake Cauma

Surrounded by thick forest on three sides in the Graubünden near Flims, the beautiful turquoise waters of this wonderful wild swimming spot are known for their pleasant 17-20C temperatures. Soak up the sun on the beach, lunch at the restaurant, have a game of volleyball, explore the waters by breaststroke or pedalo or have a go at stand-up paddleboarding, finishing up on the lake’s central wooded island for ultimate tranquillity. No wonder its Romansh name translates as ‘lake siesta’.
