West Texas winds transform an ever-changing landscape of sand dunes at the 3,840-acre Monahans Sandhills State Park. The field of dunes begins south of Monahans and stretches north into New Mexico. Opened in 1957, the state park harbors a peaceful Chihuahuan Desert playground where people can explore the rolling landscape, slide down the hills, picnic, camp, and take in extraordinary sunrises and sunsets.
