From Bessheim to walk up to Bessvatnet(lake). It is 400 high-altitude meters, and an adult uses around one hour. The hike is quite steep. The hike ascends past the old mountain farm here at Bessheim, straight to the top. After a while the trail leads somewhat to the left, and once done ascending you will reach the river Bessa. The remaining hike then follows Bessa until you reach Bessvassosen. On this hike you will get a view of the entire valley Sjodalen. Once you reach Bessvatnet(lake) you will get a view of the most majestic mountain in Jotunheimen, Besshø 2258 MASL. Halfway in the hike you will find areas in the river that is suiteable to swim in.
Ski: Follow to the marked trail to Glitterheim, that goes by Bessvatnet(lake).
