No special access issues
From Korgen (E6), follow signs to Leirskardalen. You will be driving through a narrow valley, where the road turns into a gravel path after a while. Follow the road all the way up to the summer parking. There is usually plenty of parking spots available. Mark that early in the season, the road can be closed due to snow.
Most of the boulders are easily visible after walking up a short hill from the parking space.
