The Sinkhole is a vertical cavern with an opening approximately 40 by 60 feet
and a vertical drop of about 140 feet to the main cavern. The main cavern is
circular and reaches a total depth of 350–400 feet. Freshwater lakes around its
perimeter support an endemic amphipod, as well as a rare aquatic isopod. Both
are crustaceans. There is a large seasonal population of Mexican freetail bats
that put on an evening show when they leave the cave to forage. Tours to see the
bats are available from mid-April through mid-October, and guided tours to the
cavern are available every evening. Open daily. Visitors center at Devils
Sinkhole Society: 830/683-BATS (2287). www.devilssinkhole.org.
