After descending the ropes through the gorge, there's a steep section with lots of loose rocks. I wouldn't classify this as average, but rather as difficult (and quite dangerous). The rest of the route is very scenic.

This beautiful (private) hut offers outstanding views halfway up Gyrihaugen. It'll whet your appetite and provide you with strength for the final meters to the summit.

Caution when climbing through Mørgonga, especially with regard to scree. There is an acute danger of rockfall for hikers scrambling over a rock or for oncoming traffic.
