PARK CLOSURES: On Saturday, April 8, 2017, Rock Island State Park and the Tennessee Valley Authority will be conducting public tours of the Great Falls Dam powerhouse, in celebration of the dam’s 100th anniversary. Twin Falls and the Twin Falls parking area will be closed to all outside guests. Large portions of the beach parking lots will also be closed to all outside guests.

Our launch ramp on Center Hill Lake and other ramps closeby on the Caney Fork and Collilns Rivers offer access for great recreational boating. Rock Island is known for it's whitewater kayaking and has hosted international freestyle kayaking events. Some areas of the park are for experienced whitewater kayakers or canoeists only and can be dangerous.
Use extreme caution in all gorge areas. Water levels and currents can change quickly downstream of TVA's powerhouse, or dam without notice. Large amounts of water may be released at any time without warning. Exit immediately if you hear warning sirens or notice changes in conditions. Always wear your PDF and check both generation and dam daily water release schedules for TVA Great Falls prior to visiting. For further information call 800-238-2264 option 4, (#36) or visit http://www.tva.gov/lakes/gfh_r.htm.
The park's natural sand beach is located on the headwaters of the beautiful Center Hill Lake. Adequate parking space and a modern bathhouse are provided. No lifeguards on duty. Always use caution in the gorge. Water may rise rapidly. Monitor your surroundings. Leave the gorge immediately if water begins to rise or you hear warning sirens. Watch for slick rocks and swift currents. Do not jump into water of unknown depths. Swimming or wading is not allowed in all areas from TVA’s powerhouse downstream all the way down to the main beach boat ramp including by the powerhouse, Twin Falls and Blue Hole due to hidden and deadly currents.
Birds such as Osprey, Belted Kingfisher, Black-crowned Night Herons can be seen along with Great Blue Herons which have a rookery nearby.

The park has nine hiking trails with the Caney Fork Gorge area located below the dam being a very popular area for rock hopping, swimming and fishing.

Boating and fishing are very popular on Center Hill Lake as well as on Great Falls Lake. There is a free public launching ramp on Great Falls Lake. The Blue Hole, on Center Hill Lake, lies adjacent to the park shore and is the spawning ground for the walleye in Center Hill Lake. It is considered one of the finest fishing places in the state. It is accessible via a boat launching ramp located in the park. Fishing is best in the spring, but visitors enjoy boat riding and skiing well into the fall. Catches include bass, muskellunge, bluegill, walleye, crappie and catfish. Valid TN Fishing license is required.
Due to renovation construction at Center Hill Dam and resulting lowered lake levels, please call the park office for most current status and availability of the boat ramps at the park.
