Caumasee, Mountain lake in Flims, Switzerland
Caumasee is a mountain lake in Flims surrounded by thick forests that drop steeply to the water's edge. The water appears bright turquoise and is cold year-round, with the lake sitting in a narrow valley at high elevation.
A prehistoric rock collapse shaped the basin where the lake now sits, an event that occurred thousands of years ago. This ancient movement of earth created the enclosed valley that protects the forest and water today.
The Romansh name 'Lag la Cauma' means Lake of Siesta, showing how local culture values rest and quiet time in mountain spaces. Visitors walking here often sit on the banks and simply watch the water, making it a place where people naturally slow down.
The lake sits a short walk from Flims village, with clear paths leading down through the forest to the water. A chairlift runs during warmer months and offers an easier way back up for those who prefer to avoid the climb.
The lake is fed by hidden underground springs that flow beneath the surface, causing water levels to rise and fall with no visible inlet or outlet. This concealed water system means the lake changes quietly, keeping its source a mystery to those who visit.
