Things to Do
Tennessee state parks stretch across three distinct regions — the Great Smoky Mountains in the east, the Cumberland Plateau’s gorges and waterfalls in the middle, and the Mississippi River bluffs in the west. Activities include hiking past some of the tallest waterfalls east of the Mississippi, swimming in lakes and park pools, fishing in world-class smallmouth bass streams, camping in forested mountain settings, kayaking scenic rivers, mountain biking at premier trail systems, golfing at park courses, horseback riding through valleys, and exploring Civil War battlefields and Native American mound sites. Fall Creek Falls (256 feet) is one of the most spectacular waterfalls in the eastern United States.
Best Time to Visit
Tennessee parks offer true four-season appeal. Spring (April–May) brings wildflowers, peak waterfall flow, and comfortable temperatures. Summer (June–August) is warm and humid — lake swimming, park pools, and mountain elevation provide relief. Fall (October–November) is the crown jewel — Tennessee’s fall color rivals New England at a fraction of the crowds, peaking mid-to-late October across the state. Winter (December–February) is mild in West Tennessee and cold in the mountains, offering quiet trails and solitude. The Great Smoky Mountains region experiences peak visitation in summer and October — plan accordingly.
