Organ Mountains–Desert Peaks National Monument
Four mountain ranges protect Chihuahuan Desert ecology, Indigenous sites, Butterfield routes, ranching history, and a skyline that defines Las Cruces.
Artwork inspired by Tom Lea
The monument is a network of landscapes rather than one gate: The Organ Mountains rise sharply east of Las Cruces, while the Doña Ana, Potrillo, and Robledo ranges protect volcanic terrain, grasslands, fossils, archaeological sites, and travel corridors. Dripping Springs Natural Area is the most developed first stop, with trails to historic resort and sanatorium ruins.
Choose a district before leaving pavement. Organ Mountain trails can be steep and exposed; Potrillo backcountry can require high-clearance travel and advanced navigation. Border enforcement activity may be visible, and archaeological or historic objects must remain in place.

Good to know
The monument has no single visitor entrance. For a first visit, navigate to Dripping Springs Natural Area rather than a generic monument pin. Carry more water than expected, check fire and road restrictions, and do not assume a rental car is suitable for remote Potrillo routes.
