The Davos Lake
The Davos Lake was formed more than 15,000 years ago, towards the end of the last Ice Age. A massive prehistoric landslide blocked the valley, creating a natural barrier behind which water gradually collected. Today, the lake is approximately 1.5 kilometres long, up to 570 metres wide and reaches a maximum depth of 54 metres. Its shoreline measures around 3.8 kilometres, with a walking path circling the water.
Summer brings swimming, sailing, paddleboarding and pedal boating, while the surrounding lakeside paths are popular with walkers, runners and cyclists. The lake's public beach, first opened in 1929, has been a favourite summer gathering place for generations.
Winter transforms the landscape, with snow-covered forests and mountains creating a peaceful Alpine setting. Historically, the frozen lake was also used for winter sports, including the rather unusual pastime of skiing behind horses!
A Fascinating History:
Ice Harvesting – Before Refrigerators Existed: During the 19th century, the frozen Davos Lake was an important source of natural ice. Large blocks were cut from the lake during winter and transported by railway to hotels and businesses across Switzerland to preserve food and cool drinks. In 1897 alone, an impressive 454 railway wagonloads of ice were transported from Davos.
Hydroelectric Power Since 1925: The Davos Lake is not only a beautiful natural lake but also an important source of renewable energy. Since 1925, its water has been channelled through a network of tunnels and pipes to a hydroelectric power station in nearby Klosters. Thanks to the natural difference in altitude, no artificial dam was needed. The power station generates approximately 8 million kilowatt-hours of electricity annually, enough to supply around 1,700 households.
Over 700 Years of Fishing History: Fishing has been part of life on the Davos Lake for centuries. Historical records dating back to 1289 mention fishing rights granted to local residents. The lake is home to several freshwater fish species, including trout, Arctic char and perch.
From Horse-Drawn Skiing to Watersports: In the early 20th century, the frozen lake was used for horse-drawn skiing competitions, a popular winter activity until around 1922. As tourism developed, the lake became increasingly popular for summer recreation. The public beach opened in 1929, and the Davos Sailing Club was established in 1967, helping to develop the lake's watersports traditions.
