Located on Lookout Mountain and part of the Chickamauga & Chattanooga National Military Park is Sunset Rock. The hike to the rock is a grueling .25 mile hike down from the parking lot to the rock. Overlooking Moccasin Bend and west Chattanooga the rock offers a great place to watch (you guessed it) the sunset behind the river.
Last time I was there for sunset the entire river turned pink and purple (from the sun not from some massive pepto bismol spill or something).
Anyways this hike isn’t much of a hike but it does offer a great view and if you need a bit more hiking you can start at the Cravens House site and hike up the mountain from there.
