Most lists of the best camping in Texas stop at the view. Almost none of them tell you whether your trailer fits the site, what the loop is wired for, or where the nearest dump station is, which is the part that decides whether you can actually park there.
These ten are worth the drive. Each one below carries the camping facts that matter when you tow, taken from the park’s own pages on October 5, 2026. Loops close, limits change and construction happens, so call the park before a long haul. The italic line under each park is the detail that decides whether you fit.
1. Inks Lake State Park, near Burnet
Pink granite shoreline on a Hill Country lake, with swimming at Devil’s Waterhole.
The electric loops carry water and 30/50-amp service. The water-only loop, sites 300 through 349, takes one RV per site, under 26 feet.
2. Lake Bob Sandlin State Park, near Pittsburg
Pine and hardwood on a quiet East Texas lake, with fishing piers and a swimming area.
Water and 30-amp electric. Thirty amps runs one air conditioner at a time, which is all most small trailers ask for anyway.
3. Palo Duro Canyon State Park, near Canyon
You camp on the canyon floor with the red rock above you, in the Panhandle where nobody expects scenery like it.
Mesquite and Sagebrush have water with 30/50-amp. Hackberry has water with 20/30-amp. The water-only area at Fortress Cliff is tents only: no pop-ups, no travel trailers, no motor homes.
4. Guadalupe River State Park, near Spring Branch
River frontage under cypress, an hour from San Antonio, which makes it the easiest of these to reach on a Friday night.
Turkey Sink has water with 50-amp. Cedar Sage has water with 30-amp and does not allow generators.
5. Big Bend National Park, near Terlingua
Desert, river and mountains in one park, with night skies that take a day to get used to.
This is the one to plan around. The park does not recommend trailers over 20 feet or RVs over 24 feet at Chisos Basin, because the road in is narrow and winding and the sites are small and unlevel. The only full hookups in the park are the 25 sites at Rio Grande Village RV Campground, run by the park concessioner. Everything else is dry camping.
6. Colorado Bend State Park, near Bend
Gorman Falls and guided wild cave tours, far enough out that the sky goes properly dark.
No hookups of any kind, anywhere in the park. The drive-up primitive sites take self-contained RVs up to 20 feet, so a 24-foot trailer is out. Water is in the area but not at the sites.
7. Davis Mountains State Park, near Fort Davis
High desert mountains that stay cooler than the rest of West Texas, with McDonald Observatory up the road.
Twenty-six full-hookup sites with water, sewer and both 30 and 50 amp. The electric loop is 20/30-amp with water, and the water-only sites share spigots between several campsites.
8. Big Thicket National Preserve, near Kountze
Swamp, pine and bayou within an hour of Beaumont, and birding that pulls people across the country.
Camping here is backcountry only: woods and riverside sandbars, reached on foot. There is no developed campground and no hookups, so plan it as a day trip and leave the trailer on power somewhere else.
9. Padre Island National Seashore, near Corpus Christi
Undeveloped Gulf coastline, where the campground faces open water instead of a row of condos.
Malaquite Campground has no hookups. There is an RV dump station and a freshwater fill next to the campground entrance, which is what makes a few dry nights here workable.
10. Garner State Park, near Concan
Swimming and tubing on the Frio River, and the park Texans grew up going to.
New Garner has full hookups on pull-through sites: water, sewer and 20/30/50-amp. Rio Frio and Live Oak hold 137 sites at 20/30/50-amp, and River Crossing and Shady Meadows add 35 at 30-amp. The water-only areas cap trailers at 20 feet. Live Oak closes in January and February.
What to check before you book
Measure the trailer, not the truck. Length limits are set per site and they bite hardest in the water-only loops: Colorado Bend stops at 20 feet, Garner’s water-only areas do the same, and Inks Lake allows 26.
Thirty amps and fifty amps are different plugs and different capacities. Several of these parks have both, in separate loops, at the same price.
Know where the dump station is before you need it. At Padre Island it sits by the campground entrance. In Big Bend you are dry camping unless you booked the concessioner’s RV sites.
Call ahead when the drive is long. A closed loop is a cheap phone call and an expensive surprise.
Where trailer length actually matters
Four of the ten spots above put a hard number on trailer length, and two of them stop at 20 feet. That is worth knowing before you shop rather than after.
Oliver’s 18'5" Legacy Elite fits the 20-foot loops and sits inside the Chisos Basin guidance at Big Bend. The 24' Legacy Elite II and Apex X23 need the standard and full-hookup loops, and they are better company when you are staying a week. Lengths, weights and floor plans for all three are on the travel trailers page.
If the trip is a January one, Davis Mountains and Palo Duro both get cold enough to matter, and four-season camping covers what that asks of a trailer.
