After crossing the lake by boat (there is no alternative way to reach the start), a well-marked hiking trail (follow the red markers) leads you to the glacier.
The walk takes place on solid rock and begins with a steady climb before levelling out as you approach a glacial lake that remains unfrozen in summer.
At the end of the signposted path, there is a shelter and a DANGER sign warning of the risks of getting any closer to the glacier.
From this point, you can admire the Austerdalsisen glacier, which no longer reaches down to the glacial lake due to global warming (the map is out of date).
Experienced hikers or those accompanied by a guide may extend the walk by crossing the rocky area (no marked path) to get closer to the glacier and then walking on the glacier (with suitable equipment).
