Fern Cave Preserve

Fern Cave
The Kay Hill Deen Fern Cave Preserve, is a privately owned tract adjoining the federally-owned Fern Cave National Wildlife Refuge. Fern Cave has five entrances. Four of these are on the Fern Cave National Wildlife Refuge (US Department of the Interior), and one (The Fern Sink, or Surprise Pit entrance) is located on property the SCCi owns. One section of the cave is the largest gray bat hibernaculum in the country. As a result, new restrictions are now in place to protect the bat colony from White Nose Syndrome.
