From Hemsedal town centre drive to Hemsedal Skisenter and take the toll road to Holdeskaret. Drive until you see the signpost for Røggjin on the the right hand side. Follow the blue marked path up the mountain. Above a cabin the path split, steep route straight ahead, easier route to the right.
More demanding trip-approx. 350 m vertical and approx. 2 km one way.
