No special access issues
From Sogndal drive towards Oslo. When you get to the tunnel called Lærdalstunnelen, continue 10 km on E16 towards Oslo. Turn right towards Hønjum and drive across the river before you turn right again. Park after about 300 meters on the right side of a red rental cabin. The wall is easily seen from the parking area.
New owners do not want climbing. So the wall is currently closed.
