Visitors can see 50 million year old fossilized limestone encrusted with ancient sea shells from the Tallahatta Formation marine ecosystem. Every spring hikers enjoy a stunning display of one of the state's largest populations of rare trillium. The endangered blossoms are clustered among fossils and other protected plant species. They reach for the sun through a blanket of leaves beneath the branches of old-growth beech and magnolia. A shady walking trail weaves along a ridge through wildflowers, palmettos and moss draped hardwoods. Two viewing decks are nestled above expansive vistas and offer birdwatchers refuge to see soaring hawks, woodpeckers, herons and flocks of migratory species. Climb the dry bluffs and watch for sparkleberry, yucca, mountain catchfly and shortleaf pine. Trails are open only to foot traffic. Crook's Landing boat ramp provides access to the Flint River. Boaters can enjoy magnificent views of the bluffs while exploring the swampy creeks and sandbars below.
