This is a very nice park administered by the City of Houston Parks Dept. and Montgomery County. The park is about 5000 acres and has 26 miles of hiking trails. You can tent camp or camp in an RV, not a lot of RV spots so book early but they do have full hookups which is nice. We were in #2 on the Red Oak loop which encircles Lake Dabney, a small man made lake. Each campsite has a fire ring and a picnic table. The staff we interacted with were really nice. There is a $3 daily admission fee but only for people 13-64, so kids and seniors can enter at no charge. Our RV site was $32 which was fair since it had full hookups as mentioned. There were nice restrooms nearby, albeit they were not heated so a bit cold on a frosty morning, there are also private shower rooms which we did not use.
