Only 40 minutes from la Gouille or an hour and a half from Arolla, both in summer and wintertime, there is a surprise waiting for you that will have you marvel at a vibrant blue lake.
How can such an intense colour be possible? Quite simply by the upstream water trickling over algae and the glacial clay.
Don’t miss this jewel!
