Meramec State Park

Park Information

The Meramec River flows by majestic bluffs, wooded areas and a dramatic cave entrance. More than 13 miles of hiking trails are available for exploring the park, and visitors can swim, fish, raft and boat in the river. A modern campground, cabins and motel give visitors a choice to stay the night or even longer. Exhibits in the visitor center interpret the natural and cultural features of the park. No visit to the park would be complete without a tour of Fisher Cave with handheld lights.
