This is a very unusual emerald-green lake. In May-June, the green valley is filled with meltwater that flows down from the neighboring mountains and glaciers, and the green lawn turns into the bottom of a green lake The lake is 12 meters deep. Divers can sit on benches or swim over the hiking trails right under the water. Then the meltwater subsides and the lake remains only in the lowest part of the valley, with a depth of only 1-3 meters of very cold green water.
