The Sand Wash Basin Herd Management Area is one of Colorado's signature wild-horse landscapes — a wide-open basin of more than 157,000 acres of public, private, and state land in northwest Colorado's Moffat County, about 45 miles west of Craig near the small community of Maybell. The BLM manages the basin both for its free-roaming horses and as important wildlife habitat across this high-desert country.

On the ground
Sand Wash Basin is described by the BLM as one of Colorado's special places, prized for its wild horses, wide-open range, and important wildlife habitat. The herd management area covers 157,730 acres in total — the great majority of it public land — set in the high desert of Moffat County in the state's far northwest corner, roughly 45 miles west of Craig near Maybell.
Like every herd on Western public land, the Sand Wash horses are free-roaming animals protected by the BLM under the 1971 Wild Free-Roaming Horses and Burros Act. The respectful way to enjoy them is from a distance: bring binoculars, stay back, never feed or attempt to approach a horse, and let the herd move and graze undisturbed. The BLM manages the population toward an appropriate level of 163 to 362 animals.
This is remote, services-light country where a self-contained RV makes sense — carry plenty of water and fuel, and stay on designated routes to protect the basin's fragile habitat. Check the official BLM source for current access, road conditions, and any management activity before planning a visit.
