Rhône Glacier Ice Grotto
Rhonegletscher
The glacier at the source of the Rhone River. In summer you can walk into a man-made blue ice cave, and parts of the glacier are covered with insulating blankets.
The Rhone Glacier lies at the head of the Goms Valley, on the west side of the Furka Pass, and is the source of the Rhone River. Each year a tunnel about 100 meters long is carved into the ice, and its walls glow deep blue. To slow melting, some sections of the glacier are covered with white insulating blankets, which clearly show how much the glacier has retreated. From Fiesch, it is about an hour by car along the Goms Valley through Gletsch. The ice cave requires a separate ticket and is accessible only in summer, when the road is open.
Opening hours
About Jun–Oct, 08:00–18:00 (depends on road opening)
