This long, narrow cave is renowned for its animal engravings, notably mammoths, horses, reindeer and human figures plus a fantastic mountain lion that seems to leap from the rock face. Buy tickets at Font de Gaume, then drive 1.5km further east to the entrance, arriving 10 minutes before the time slot on your ticket.
Only 42 people per day are allowed entry, in groups of seven. The 45-minute tour is not for claustrophobes.
