The area is access sensitive
Normally March through August, every year, peregrine falcons are hatching in the area. Most of the bouldering is pretty far from the hatching spots, but check in with the local climbing club (Drammen klatreklubb) first.
Parking should be done at the marked area, there is space for many cars. Follow path south to "Øvre Svarttjern" - approx 800 m walk.
