This year, a cave in Val Morteratsch fascinates with its blue tones and special atmosphere. We meet at Morteratsch railway station. The following 2-hour snowshoe hike takes us through the glacier forefield to the foot of the Morteratsch glacier. At the entrance to the grotto we leave the daylight behind and dive into the fascinating world of ice. After about an hour we then make our way back to Morteratsch station.
