Thousand Trails Colorado River RV Park is very conveniently located just five miles off I-10 between Houston and San Antonio. This campground is a nice mix of amenities and natural areas and is a great spot to stop for a few days or even a bit longer. We stayed at Thousand Trails Colorado River RV Park for four nights in January 2020. We were on a cross-country trip from Florida to Nevada and picked this location to rest for a few days before continuing west. We arrived on a Saturday, and unfortunately all the full hookup sites were occupied and we ended up with a water/electric site. Fortunately, we were only staying a few days, so after dumping our tanks we settled into site D4.
