USFS. This is the Neches Bluff Overlook area just off of highway 21 in Davy Crockett National Forest. It is the Northern trailhead for the 20 mile 4C trail, which ends in Ratcliff Lake Recreation Area on highway 7.
Ratcliff is a paid recreation area, but this northern site is completely free for camping and day use and includes at least one geocache. There’s a decent view of the Neches River bottom from a platform near the restroom.
This area is also very popular with hunters during deer season, so be aware if you’re not there to hunt at that time. Some nearby towns are Crockett, Lufkin, and Ratcliff, where the Ranger Station is located.
