We stayed here for 2 nights in early May 2019. We stayed in the Hackberry campground. The park was completely full, and we grabbed the last spot 30 ft spot available. This park is beautiful, and I can see where it gets it name “ The Grand Canyon of Texas”. They had some rain recently when we there so everything was green and beautiful against the canyon walls. We didn’t have much time since we were only able to stay two nights, but I feel we were able to explore enough in those two days. I would recommend doing to the hike to Lighthouse Rock. 2.7 miles one-way and then when you get there, it’s about another .4 hike up to the area where you can see it. I would also recommend you go to the Big Cave. Very short walk for that and neat. The park has a 10% grade and all campgrounds are at the bottom of the canyon. We had no trouble in our 30 ft travel trailer with our Ram 2500. The visitor center had a disappointing selection of souvenirs but go there for the view. We stayed on site #2 in Hackberry which was 30 ft long. We had no trouble getting in and had enough room to park the truck in front of the trailer (at an angle). Site was level as well. We had no cell service at all without a booster. With a booster, we had no Verizon, but enough AT&T to use internet. We were even able to stream Game of Thrones one evening. The park was quiet at night. I would have liked to have stayed maybe one more night to explore more, but two days worked for us. Nothing around the park as far as services, so bring what you need. There is a store at the park that has a few essentials at a high cost. Overall, I was a great stay and we would stay again. $24 price reflects camping only. There is also a $8/person day use fee if you do not have a Texas State Park pass.
