Best time to visit Lake Somerville State Park & Trailway

Spring, from March through May, is the top window for RV trips thanks to mild temperatures, active wildflower blooms, and comfortable hiking conditions along the Trailway. Fall, from late September through November, is the strong shoulder season with cooler evenings, lower humidity, and reduced crowds. Summer brings hot, humid days that push most activity to the water and early mornings, while winter stays mostly mild but can bring cold fronts and occasional freezes that affect water hookups.

Things to do at Lake Somerville State Park & Trailway

  • Lake Somerville Trailway Moderate
    RV parking available

    The Trailway is a primitive multi-use path that links the Birch Creek and Nails Creek units through open grassland and post oak woods. Hikers, mountain bikers, and equestrians share the corridor, with backcountry camping available at designated primitive areas. RVers typically stage at either unit and day-hike out from the trailheads.

  • Fishing on Lake Somerville
    RV parking available

    Lake Somerville is a popular fishing destination for largemouth bass, white bass, crappie, and catfish. Both units have boat ramps and lighted fishing piers within walking distance of campground loops.

  • Boating and paddling
    RV parking available

    The lake is open to powerboats, kayaks, and canoes, with public boat ramps at both the Birch Creek and Nails Creek units. Shoreline paddling is common in the protected coves near the campgrounds.

  • Swimming and lake beaches
    RV parking available

    Designated swim areas along the shoreline give RV families a spot to cool off in summer. There are no lifeguards, so swimmers enter at their own risk.

  • Wildlife and bird watching Easy
    RV parking available

    The mix of lake, grassland, and woods supports deer, armadillos, and a wide range of resident and migratory birds. Spring and fall are strong windows for spotting waterfowl and songbirds along the Trailway and shoreline.

  • Wildflower viewing Easy
    RV parking available

    In spring, bluebonnets, Indian paintbrush, and other Texas wildflowers bloom across the park's open meadows and Trailway corridor. Short interpretive walks from the campgrounds offer easy photo stops without needing to move the RV.

  • Equestrian trail riding Moderate
    RV parking available

    The Trailway permits horses on designated segments, with equestrian staging and primitive equestrian camping at Nails Creek. Riders should check current conditions, as sections can close temporarily after heavy rain.

We were able to explore Lake Summerville and do it in a comfortable environment. The owner of my RV was extremely responsive whenever I reached out with questions. The RV itself had a comfortable beds, and everything was in working order except for one light. I would rent this RV again.
