The walk-in entrance to the cave leads to a long, winding passageway that opens into corridors and galleries decorated with unusual boxwork and frostwork formations that are illuminated by indirect light.
At the edge of the Great Plains, the park is a biome composed of a natural mixture of plant and animal species indigenous to several larger regions. The park is about 70 percent prairie grassland and 30 percent forest.
Large mammals such as bison, deer, elk and pronghorn antelope can be seen from the park roads. Prairie dogs and rabbits are a common sight, while coyotes, porcupines, eagles, owls and wild turkeys are spotted occasionally. Do not approach the wildlife; bison are wild and unpredictable. Hunting is prohibited.
