Graham Cave State Park

Park Information

A walk in Graham Cave State Park is a walk through ancient history. Artifacts uncovered in Graham Cave reveal that people occupied the cave 8,000 to 10,000 years ago. To walk through the park’s 386 scenic acres, which includes the diverse Graham Cave Glades Natural Area, is to walk in the footsteps of the hunter-gatherers who lived in the area’s caves during the ancient Dalton and Archaic period. Visitors can go into the mouth of Graham Cave, and interpretive exhibits along Graham Cave Trail detail the life researchers believe early inhabitants lived. Additional interpretive exhibits throughout the park explain the cultural and natural significance of the site. Graham Cave State Park is a prime hiking location, and the campground is perfect for get-togethers in a quiet place. A boat ramp to the Loutre River provides access for boating and fishing.
