We stopped in when we missed out on a spot at Zapata Falls earlier in the day. The road is rough coming up and some of the sites aren’t the most level, but there was plenty of space- we drove in and picked whatever looked good as it wasn’t busy when we visited. Showers very clean, drinking water available. Gorgeous view of the dunes at sunset. There is a general store/restaurant on premises for any odds and ends. Most importantly, only about 2 miles from the entrance to the park!
