Caving responsibly

Most wild caves are reached through the local caving community, not by showing up — joining a grotto gets you training, gear advice, a conservation ethic, and, in time, cave locations.

Trails (0)

A trail records the way through a cave — walk it once and anyone can follow it back in or out. Near the entrance with GPS it replays in AR; deep underground it's a compass guide (no signal needed).
