Short 2-3 minute hike down a set of steps with very little uneven terrain. Great for beginners who want beautiful views without a 2-3 hour hike. Overlooks west Chattanooga and the Tennessee River. Parking is sometimes limited so I would go early if you are actually hoping to catch sunset. Just minutes from Sunset Rock you can find Point Park which has ample parking and beautiful views, as well. They do charge a small entrance fee at certain times.
The list wouldn't be complete without including the place where Ryan proposed! This park has always been one of our favorite places for a short walk by the river. The park is located on the Northshore side just steps away from Walnut Street Bridge.
