Martin Dies Jr. State Park offers over 200 campsites (most with water/electric hookups) plus screened shelters and cabins, with many sites adjacent to B. A. Steinhagen Reservoir and sloughs ideal for paddling the Neches and Angelina rivers.

The park features boat ramps, canoe/kayak launches, a fish cleaning facility, and comprehensive amenities including dump stations, hot showers, and a park store.

Reservations are highly recommended as the park frequently reaches capacity, especially during peak seasons (March-July and September-Thanksgiving).
