The best part of this park is the observatory, which has special events and regular weekend hours pretty much all year. It’s absolutely worth staying up late for this! Hikes and wildlife are good too, lots of easy trails along water for the kids, cool ponds, great little observation tour to climb. There are standard RV/tent sites, screened shelters (for sleeping), and rustic cabins, horse sites, and youth group sites. The sites are pretty spread out and maybe half of them are very shady. Awesome little park outside Houston.
