Illinois Caverns is a Speleologyriver cave with a small cave river. It is the only cave that has been operated commercially in Illinois. Its entrance is developed and protected by an iron gate, and a part of the cave is developed with paths and once had electric light. But the cave never was a commercial success.

Today cave tours are cave trekking tours with a very low severity. The cave has about 5.8km of walking-height passage, but some of it through the knee-deep cave stream. There are no paths or lights on this tours. Illinois Department of Natural Resources, the owner of the caves, allows cave trekking tours by visitors who fulfill the permit requirements. Groups with a minimum of four persons can navigate their way through the cave "on their own", a map of the cave is provided with a brochure.

The necessary equipment are at least three light sources per person, helmets, Wellingtons, old and warm clothes. It is possible to change clothing at a changing hut at the cave entrance, but there is no possibility for a shower, as there is no water. For more info read the official website below.

The cave has an outstanding invertebrate fauna, including gammerus acherondytes, the Illinois Cave Amphipod. It houses numerous Biologytroglobites like the cave salamander and two species of bats, the Little Brown and Eastern Pipistrel.

The cave was explored and surveyed by the Windy City Grotto.
