Harrison Bay State Park is a 1,200-acre Tennessee state park on Chickamauga Lake. It opened in 1937 as a state demonstration park developed by the Tennessee Valley Authority during the 1930s, alongside nearby Booker T. Washington State Park. Harrison Bay takes its name from the town of Harrison, Tennessee, which was partially submerged when the lake was created. The park is centered on the water and includes a 4.2-mile lakeshore hiking trail as well as recreational amenities such as a swimming pool, playground, golf course, tennis courts, restaurant, campground, and marina.
