Access info missing
After taking the turn (just before the road leads down into the Ou Poort gulley), drive along the dirt track past Powerlines and park a the extended parking down at the end of the field. From the parking follow the well cairned path towards the rock slab and into the valley.
The main approach is under 300 meters, which is around 3 minutes.
The distance to Jungle bar and Ian's Roof are both around 700-800 meters from the Derailed boulder.
