TIME: 2 hours (Or 1 hour if driving part way).
DISTANCE: 6 km return.
TERRAIN: Undulating path.
Walk (or drive, there is room to park at the start of the walk proper) from the visitor centre back towards the entrance gate. Immediately after crossing the second bridge park your car and meet an authorised guide. Unaccompanied visits are no longer permitted because of continued damage to the paintings. They are now quite faint and easily missed without the guide. Turn up a sign-posted path to the left. This leads directly to the paintings. The guide will interpret them.
