Harrison Bay State Park is a 1,200 acre park with approximately 40 miles of Chickamauga Lake shoreline, and was originally developed as a Tennessee Valley Authority (TVA) recreation area in the 1930s. Its name is derived from a large bay at the main channel of the Tennessee River that covers the old town of Harrison, and the last Cherokee Campground. The parklands are historically significant because the Cherokee Campground consisted of three villages which were ruled by one of the last great Cherokee Chieftains. Harrison Bay became the first Tennessee State Park in 1937.

This beautiful wooded park is a haven for campers, golfers, boaters and fishermen, as well as picnickers and other day-use visitors from Chattanooga and the surrounding tri-state area. It has one of the most complete marina facilities available on any of the TVA lakes and all types of boats and water recreation vehicles are allowed at the park.
