Monahans Sandhills State park is 3840 acres of sand and about 3 miles of paved road and campsites. One of the main tasks of the park staff is keeping the sand off the paved roads. All this sand creates dunes up to 70 feet high. The dunes are ideal for climbing and rolling down or you can rent a "Sand Disk", climb to the top of the highest hill you can see and ride down.
If the winds are high it's very hard to enjoy the park. The blowing sands not only rebuild and relocate the dunes it will also sting your legs and put sand in your eyes. The summer sun also makes the sand so hot that it will burn your feet. However nice winter days and summer evenings are ideal time to play in the sand.
The park has an 800-acre equestrian area with no marked trails. A trailer parking area is provided and has a fenced corral where riders can tie and water their horses. Potable water is available in the area. It is BYOH. (Bring your own horse)
There is a lot of day use areas and 24 over night campsites with water and electric hookups. These sites are good for RV's but I don't recommend camping in a tent. (Have you ever tried to drive tent stakes in the sand?)
