Davosersee is a natural alpine lake at the northern end of the valley, about 2 km from Davos Dorf. In summer it is Davos's swimming lake — the water is cold and clear, fed by snowmelt from the surrounding peaks, and the setting, surrounded by forest with mountains rising on all sides, is excellent. A small lido area has changing facilities and a café.
In winter the lake freezes and provides what locals consider the most beautiful skating in Europe: skating on natural ice in the open air, with mountain views in every direction. The ice is maintained and safe to skate on when conditions allow; skating equipment can be hired. The lake is a 15-minute walk from Davos Dorf railway station.
