Attractions and activities include split-nose bats, caves, spelunking, fishing, swimming, snorkeling, scuba diving and diving from the high steep rock surface down to the sea water.
Technically, these arachnids are harmless to humans -- though they're not exactly something you want to find crawling up your arm as you're spelunking.
Activities available through the trip programs include whitewater rafting, rock climbing, backpacking, canoeing, surfing, skateboarding, spelunking, volunteer service, biking, sea kayaking, and high ropes.
The cause of the decline is thought to be human sport, including spelunking, and general human disturbance in caves inhabited by the bats, which have lower tolerance to outside activity.
