The walk follows the main road from Turtagrø as far as the second bend and then goes by a road up Helgedalen. High up in Helgedalen you pass the intake to a tunnel feeding water to the Fortun hydro-electric power station. The walk then swings steeply up to the Keiserpasset - Skogadalsbøen road fork. From here a good path twists and turns up to Fannaråken.
The view from Fannaråken is fantastic with the whole panorama of the West-Jotunheimen range. Many come to Fannaråken to experience the sunrise.
This is one of the "classic" Norwegian walks. Fannaråkhytta is the highest mountain hut in Norway ( 2068 m a.s.l.) and is manned during the summer.
