No special access issues
The fastest driving directions: From the Circle K gas station in the village centre of Bø, drive on road 36 towards Seljord for about 6.3 km. You will see a suspension bridge leading over the river on your right side. Take a right turn and drive over this bridge. After the bridge, drive on the gravel road for about 500 meters. Take a left turn when the gravel road ends, and follow the road for another 2 km. You should now have the parking on your right hand side.
NOTE: The bridge is normally closed in winter and does NOT take large cars such as large vans. However, there are several alternative routes that avoid the bridge. These roads should be easy to find in a gps or on a map, and only adds a few minutes extra to the drive.
From the parking, follow the trail right. After around 50 meters, take a left turn up through the pass. You'll have a wall on your right side for the first part of the journey. The steeper sections of the trail has ropes to help you get up with pads on your back :)
