Martin Dies Jr. State Park offers 705 acres along B. A. Steinhagen Reservoir with boat ramps, canoe/kayak launches, and paddling trails on the Neches and Angelina rivers.

The park features over 200 campsites (most with water/electric hookups), screened shelters, and cabins, plus a nature center, hiking/biking trails, and fishing access.

Day-use passes ($4 per person age 13+) are available; reservations are highly recommended as the park frequently reaches capacity, especially during busy seasons (March-July and September-Thanksgiving).
