The Cedar Bluff Trail at Castlewood State Park is one of the few trails off on its own that doesn't connect with any other trails in the park's network. The loop trail passes by an old abandoned building in the woods and has a forest scene for basically the entirety of the trail. The trees are especially beautiful in the fall months. If you want to hike in the park but don't want to see a ton of people, this trail could be what you're looking for.
