We stayed here for 5 nights at the end of March, 2023. The campground has paved roads, showers, dump station, water & electric hookups and the usual campsite set-up.
Three trails are located within the park. The campground itself is large, sites somewhat spaced apart and the grounds have a lot of stubby trees which were leafless when we were there.
A large visitor center is near the park entrance and the cavern is up the hill behind the center. We reserved and did the Rotunda/Throne Tour. It was very cool and our 1st cave tour. I would suggest reading the rules for tours before reserving. Access to the cavern is very controlled as far as how you get in and what you can take. There's quite a story about how this park came into being.
The location of the park allows quick access to the I-10 and the town of Benson, about 12 miles away. Other interesting sights are within an hour or so of the park.
