Exit caving special cavities

Underground crossing (Mégevette, excursion or sports)
A crossing consists of entering underground through a high entrance to an underground network and exiting through a low entrance. The proposed crossing will lead us after about twenty minutes to the high entrance of this network. Various obstacles, sounds, reminders, handrails, slides will be crossed to take us to the exit located a few dozen meters below. Out we will reach the vehicles in 10 minutes.
