Rock Island State Park, is an 883-acre Tennessee State Park located an hour and a half Northwest of Chattanooga, on the headwaters of Center Hill Lake at the confluence of the Caney Fork, Collins and Rock Rivers. The park is best known for its dramatic waterfalls, fishing, and boating opportunities as well as year-round camping and cabin rentals. Popular points of interest include Great Falls, Twin Falls, the Blue Hole, the Cold Hole, and the Warm Hole. This gorge is comprised of slick limestone bedrock cut by the swift currents of the Caney Fork River.

Rock Island State Park has 60 campsites, each equipped with 30 amp electrical and water hookups, grill, and picnic table. Three modern bathhouses (with hot water showers, lavatories, commodes) are located in the camping area. There is a dump station at the far end of the campground for the convenience of self-contained camping rigs. Campers must register at the park office. Campsites can be reserved online up to one year in advance, maximum stay limit is two weeks. Tent camping is also allowed. This facility is open year round.

A park boat ramp provides access to the upstream end of Center Hill Lake and just west of the main park entrance, on the south side of Highway 287, the short Kings Launch Road will take you to a boat ramp on the Collins River, both of which are excellent flatwater paddling locations.
