Fterolakka cave is a vertical cave in Parnassos. The vertical depth of the cave is 300m approximately and is considered one of the most technical caves to rig in Greece due to the existence of an active canyon and the continuous rope traverses needed to avoid the waterfalls. Recent descents are facilitated by the existence of old ropes in many parts of the traverses.

Average time needed: 1 day (assuming the cave is already rigged).
