Best time to visit Martin Dies, Jr. State Park

March through May and late September through November are the most comfortable months, with mild temperatures, lower humidity, and strong birding during spring and fall migration. Summer brings hot, humid weather, frequent thunderstorms, and heavy mosquito activity, though long daylight hours and warm water favor swimming and paddling. Winter is mild and quieter, making it a good shoulder season for RVers who want open campsites and active fishing. Expect higher weekend demand during spring break and holiday weekends.

Things to do at Martin Dies, Jr. State Park

  • Paddling the Neches Paddling Trail Easy
    RV parking available

    Paddlers can explore marked canoe and kayak routes through cypress sloughs and open coves on B.A. Steinhagen Lake. The water trails wind past flooded timber and quiet backwaters that showcase the park's swamp habitat. Rentals are available seasonally at the park.

  • Fishing B.A. Steinhagen Lake
    RV parking available

    Anglers come to B.A. Steinhagen Lake for largemouth bass, crappie, white bass, catfish, and bluegill. Bank fishing, lighted piers, and boat ramps are accessible from both sides of the park. A Texas fishing license is required outside designated state park waters.

  • Slough Trail and Island Trail hikes Easy
    RV parking available

    Short interpretive trails at Hen House Ridge and Walnut Ridge lead through bottomland forest and across footbridges into cypress islands. Routes are mostly flat and shaded, ideal for easy walks and wildlife watching. Boardwalk sections help with wet ground after rain.

  • Birding in the Big Thicket Easy
    RV parking available

    The park lies along a migration corridor and supports more than 200 recorded bird species. Spring and fall bring warblers, herons, waterfowl, and raptors, while resident species include pileated woodpeckers and barred owls. Early mornings near the sloughs offer the best viewing.

  • Boating and water sports
    RV parking available

    Boaters can launch motorboats, sailboats, and personal watercraft from multiple ramps at the park. The large lake has room for skiing and tubing in designated areas, with no-wake zones near swim beaches and boat-in campsites. Bring fenders and lines for shoreline tie-ups at day-use docks.

  • Cherokee Unit day use and swimming Easy
    RV parking available

    The Cherokee Unit on the north side of US 190 offers picnic areas, a swim beach, and fishing access. It is a good option for RVers staying elsewhere in the park who want a change of scenery. Parking is ample and accommodates trailers.

  • Wildlife viewing and alligator watching Easy
    RV parking available

    The swampy habitat is home to American alligators, river otters, white-tailed deer, and a variety of snakes and turtles. Viewing is best from boardwalks, bridges, and the water at dawn or dusk. Keep a safe distance and never feed wildlife.
