No sewage hookup that I see but a dump station. Is it very crowded?

I have been told it is one of the top visited parks in Texas. Very worth it though. Beautiful rock formations, hiking trails, and great camp sites. Went during spring break this year, very busy but it was hardly an issues. They are well set up facility wise to handle numerous visitors. You will have a great time.

Its usually the most crowded on weekends and holidays.
