Choke Canyon State Park


The Frio River Basin is a great place for a reservoir, and Choke Canyon provides most of Corpus Christi’s drinking water. But this place is a lot more than just a water source. Choke Canyon State Park is a great place to watch the sun come up over the South Texas flatlands, listen to birds rustle and sing nearby, and cast the day away in the lake.

Choke Canyon State Park is actually two parks in one. The South Shore Day Use Area is on the southeast shore close to the town of Three Rivers and adjacent to the dam. The day use area is mostly for powered boats. The Calliham Unit is about a mile to the west. This part of Choke Canyon State Park caters more to campers and fishers. Other Calliham Unit facilities include a tennis court, basketball court, and a 75-acre lake within a lake.

This park is one of the newest ones, and one of the oldest ones, in Texas. The state acquired the land in 1981, and the park opened in 1986. Much earlier, the mysterious Paleo Indians first inhabited this area in their quest for mammoth, bison, and other large game. When those animals left, so did the Paleo Indians.

Today, Choke Canyon State Park is a getaway destination for RVers looking to enjoy aquatic activities on the massive Choke Canyon Reservoir. The reservoir is truly quite large spanning across more than 25,000 acres. This provides an idyllic setting for fishing since the lake is stocked with bass, crappie, and catfish. However, you will need to keep an eye out for alligators. No matter when you visit Texas in your rig you'll want to make a stop at Choke Canyon State Park to experience all of its amazing beauty and charm.

Choke Canyon State Park is located about halfway between San Antonio and Corpus Christi just off Interstate 37. So, whichever direction you come from, the trip to the park is interstate almost all the way. Interstate 37 is mostly four-lane divided highway. It’s a bit narrow as far as interstates go, but there is still plenty of room for RVs.

Three Rivers is the closest town to Choke Canyon State Park. There are a couple of small grocery stores in town, but for your stocking-up RV camp needs, you’ll probably need to stop someplace closer to Corpus Christi or San Antonio.

Choke Canyon State Park is a rather small state park, so RV parking is a bit limited as well. There is one parking area in the South Shore Unit day use area and another one near the Callihan Unit boat launch, but that’s about it.

Seasonal activities in Choke Canyon State Park



The entire Park is open to swimmers, but beware that there are no lifeguards. Swimmers probably should stay away from the South Shore Day Use area, because of all the power boats. Although you can splash around in the no-wake area or near the dam, where boats are prohibited. The east side of the Calliham Unit is good for swimmers because the boat launch is on the west side.


Choke Canyon Reservoir has lots of open water, so it’s great for boaters. That’s especially true of the water near the South Shore Day Use Area. Once you get away from the dam and out of the 30-foot no-wake zone, you can open the throttle and go a long way. There’s not quite as much open water space around the Calliham Area, but most of these boaters are fishing boats.

Sightseeing at the Ancient Sea Bed

This place is kind of cool. Thirty million years ago, the Gulf of Mexico shoreline was about where the Choke Canyon dam is today. The land formed during the Cenozoic period, which was right after the dinosaurs died off. There is still lots of silt and sediment left from when the sea retreated, and this debris are still clearly visible today. It's not on every RV vacation that you get to see an ancient sea bed.



Choke Canyon Reservoir has some patches of cattail, water seagrass, and a few other plants. But for the most part, it is pretty much open water. The catfish and largemouth bass are usually biting. In fact, double-digit bass hauls are quite common. You might also see a few crappie and sunfish. Use spinnerbaits, rattletraps, crankbaits, buzzbaits, and unweighted soft plastic worms to catch largemouth bass during the spring, fall, and winter. In the summer, don’t bother. There are lots of white bass in the Frio River channel during the winter. Creeks and shallow areas (less than eight feet) are good catfish spots.

Bird and Wildlife Viewing

Choke Canyon State Park is a great place to see unique birds and wildlife. This part of Texas is the northernmost habitat for several species of Mexican birds, including the Mexican Eagle. These birds come here for the abundant water supply. This area is also the westernmost habitat for alligators. Other land animals include coyotes, racoons, and Rio Grande turkeys. Most of these animals live around the mesquite thickets that dot the landscape. If you want to spot any of these majestic creatures make sure to pack your binoculars in the camper.

Group Facilities

If you want a place to host a large event, Choke Canyon State Park may be a good place. The indoor Sports Complex has a sound stage, tables and chairs, bleachers, and a full-size basketball court. There’s another basketball court outside, along with a tennis court. Other group facilities include a recreation hall, dining hall, and two outdoor group pavilions.
