Description: Klaretjern is located about 1,5hrs drive from Oslo close to the border with Sweden. Follow road 106 branching off road 21 for about 1.8km to reach a small parking area on the left side. To reach the lake you have to cross the road and walk for about 100m. You can access water easily directly from this spot. There is a shallow ledge (5-6m) which then steeply drops down almost as a wall. If you follow the wall to the right the landscape is more dramatic with multiple ledges. The more interesting area is on the left side of the entry point, with a more gentle slope and fallen trees underwater. The intact trees with upturned roots and leaves are the main attraction of this site. There is no life in the lake, but the scenery is very impressive.



There are no facilities at the dive site. 

However, it is a very nice spot for camping if you would like to stay overnight.

Closest dive shop is in Halden, about 20km away, but this shop is not open on weekends:
