River Cave

River Cave is located in the Cave River Valley Natural Area managed by Spring Mill State Park. The cave serves as an important and significant winter bat hibernaculum. Entering the cave during the official closure period is a federal crime with significant penalties. Authorized access to the cave is permitted May 1 to August 31. The majority of the cave is easy walking with ankle to knee-deep water. However, the entrance section of the cave has deep water, requiring special considerations to enter. The cave can flood, so do not enter during high flow, or when there is a chance of significant rain.
