Carter Caves State Park has more than 200 caves on its ground. Six of the caves are open to the public, three are show caves with paths and electric light, and one is used for spelunking tours. Two more, Laurel Cave and Horn Hollow Cave can be explored unguided. A permit is necessary, which is available at the Welcome Center at no charge.
The park has several other karst features, for example natural bridges, which can be discovered on the various nature trails. There are more than 30km of prepared trails.
Because of the White Nose Syndrome, a disease killing 90-100% of the bats in infected caves, all caves except for park led tours of X-Cave and Cascade Cave are closed! The Department of Parks closed all the caves until further notice.
