Sea Rim State Park sits at the junction of marsh and Gulf Coast beaches in Southeast Texas, with land elevations less than 10 feet above sea level across this coastal wetland system. The park features 5.2 miles of Gulf shoreline and over 4,000 acres of marshlands accessible by kayak. Primitive beach camping areas offer direct vehicle access on firm sand, though high tides and storms can rapidly alter conditions.
What to do
Kayak the marsh trails: Sea Rim State Park has designated paddling trails through the marshes where visitors can spot wildlife. "Great kayaking trail map and recommendations from the rangers on where to go. There is hiking as well. Spend an afternoon or a week here," notes Lynn G. from Sea Rim State Park Campground.
Fish from the shoreline: Walter Umphrey State Park provides shore fishing opportunities along Sabine Lake. Located at the west end of the Sabine causeway in Port Arthur, the park offers about 15 RV sites in a parking lot arrangement. Facilities include restrooms that require keypad access and portable toilets nearby.
Explore the nature trail: The boardwalk trail at Sea Rim crosses marsh habitats with opportunities for wildlife viewing. "The nature trail over the marsh was really cool, we saw lots of alligators and birds," reports Vanessa L., who visited with her family.
What campers like
Beach proximity: Campers appreciate the convenience of sites near the Gulf shoreline. According to Joshua H. at Sea Rim State Park, "This is one of the few state parks that really does have primitive camping on the beach just yards from the seashore... It was only $12 for the night there is a roadway if you want to call that a pact sea saying it was not necessarily that crystal white sugar sand but it was the beach."
Diverse environments: The combination of marsh and beach landscapes provides varied camping experiences. "Absolutely beautiful area with diverse environment to explore. You can stay in cabins, regular RV/tent sites with power, or out on the beach with no amenities," writes a reviewer who stayed on the beach.
Privacy options: Many campsites offer good separation from neighbors. At End Of The Road RV Park, campers find "shaded waterfront RV spaces and fully furnished cabins. Quiet, safe, and peaceful park. Wifi, 90ft dock, and aluminum boats free for residents."
What you should know
Mosquito preparation: Mosquitoes can be overwhelming, particularly after sunset. "Once the sun goes down. An army of vampire mosquitos descend on you and your pets. We were enjoying being outside and we had to get into our trailer," reports Evelyn O. at Sea Rim State Park.
Gate closures: Check park operating hours before arrival. According to Katie M., "This is the only park - national, state, regional or otherwise - that I've encountered that literally locks their gate at night. The time listed on google or their website is a hard closing time, not just when the ranger goes off duty."
Weather vigilance: Coastal conditions can change rapidly. At Mae's Beach, a reviewer noted, "Beautiful spot. Unfortunately, the area was hit by Hurricane Laura in 2020 and the nearby neighborhoods have been destroyed. Locals are in the process of rebuilding. I'd suggest having 4x4 to drive on the beach."
Tips for camping with families
Cabin options: For families seeking more comfort, cabins provide amenities while maintaining outdoor access. Kim B. describes the Sea Rim accommodations: "We got a cabin and it was really nice: AC, unfurnished kitchen, comfy bunkbeds, screened deck (bring your own kitchen supplies and bedding)."
Beach activities: Plan shell collecting excursions during morning hours when temperatures are cooler. Joshua H. mentions, "There were seashells everywhere. Don't forget your bug spray because the mosquitoes do come out sometime during the day."
Wildlife viewing with children: The marshlands provide educational opportunities to observe alligators and coastal birds. Hidden Lake RV Park offers additional water activities: "A small lake with free use of canoes and peddle boat available," notes Cat R., who found it convenient for families visiting nearby attractions.
Tips from RVers
Site selection: At Gulf Coast RV Resort, Douglas T. reports: "Very nice lady called prior to our arrival to ask if she could charge our card so she could prepare the packet. When we arrived it was all ready and maybe took 5 minutes. Park was clean, plenty of length for our 42' 5th wheel and truck. Hookups were in good spots."
Leveling considerations: Some RV parks in the area have design issues affecting leveling. Caroline S. notes, "The pad is buried into the ground which cause hills into the grass. A great way to break an ankle. It also caused a hill for the sewer hose to run uphill."
Dog-friendly campgrounds near Sabine Pass: New Lloyd RV Park accommodates pets with designated areas. The park offers large, clean spots and includes tent sites, RV hookups, and cabin options for travelers with dogs. Most campgrounds in the Sabine Pass area allow pets but maintain standard leash requirements for safety.
