After 5km, you will see about two-thirds of the way up the escarpment a line of artificial caves, cut into the soft limestone. The Butentau Cave Settlement extends for some 2km northeastwards. Several hundred caves have been identified, probably occupied in early medieval times. Cave settlements have also been uncovered in several other escarpments in the region. The caves cannot be reached without climbing equipment, with a few possible exceptions where there have been rock falls, which may be accessible through a hard scramble, depending on your fitness and perception of risk.
