The easiest acces is from Skaug. Park by the Grindehus (be good and pay a tip to the community for using the parking). Follow the gravel road south east and east past the gravel pit. When the road ends a forest trial starts. Follow this east for about 500 meters till you meet a sign that says "Småvatnan". Follow the sign up hill and stay on the path. Once you reach a marchy plateau you break off trail to the right and stay in the long shallow valley. You'll soon find the boulders here. The total walk in is roughly 3 km.
