Some climbing may be involved, but a belay will always be possible. All cavers should have some experience and the trip leader has the right to exclude those who are not felt to have enough experience. Trips will be underground from 4 to 12 hours. No Hoofer trip is advanced. An advanced trip requires special skills and equipment, such as ropes, descenders and ascenders, or perhaps scuba gear.
Proper technique is learned and perfected outside of the cave.
