Not all glacial lakes benefit from the ice blue coloring. But the glacier tongue and glaciers are reflected in the water. The wonderfully refreshing feeling, next to the literally ice-cold water, invites you to take a long break on hot days.
On August 11, 2017, the glacier lake was pushed out of its bed by a massive moray eel and the moray eels and water masses caused great damage as far as the Sulzenauer hut and then further down into the valley. At that moment I was at the hut.
