Great place for sharing a Bat viewing or evening with kids/family. Learn from the State Park docents about how bats live, feed, and exist in nature.

This was a must see for outdoor enthusiasts! The bats were fascinating! Boring bat tutorial, make sure to bring exact change. Walk to the upper viewing area where the benches are to see them ascend into the sky.
