🏆 Official Guide: City of Rocks State Park — 680 acres of otherworldly volcanic rock formations (40-ft pinnacles sculpted over 34.9 million years) in Grant County, New Mexico — featuring campsites nestled among the rocks, an astronomical observatory with 14-inch telescope (first in NM state park system), internationally recognized dark skies, the Hydra Trail, Table Mountain Trail + Cienega Trail, a desert botanical garden (yucca, century plants, cacti), 120+ bird species (golden eagles, hawks), Mimbreno archaeological heritage (750–1250 AD), and Butterfield Overland Mail Route history.
City of Rocks State Park is one of the most surreal landscapes in the American Southwest — massive volcanic rock pinnacles rising up to 40 feet from the desert floor, sculpted by 34.9 million years of wind and water erosion into a maze-like “city” of monoliths, lanes, and courtyards. Found in only a few places worldwide, this geological wonder in southern New Mexico offers an unforgettable camping experience with internationally acclaimed dark skies and the state park system’s first astronomical observatory.

Frequently Asked Questions
How were the rock formations created?
The formations are volcanic ash-flow tuff from a massive eruption of the Emory Caldera approximately 34.9 million years ago. Over millions of years, wind and water erosion sculpted the hardened tuff into the maze-like pinnacles, lanes, and courtyards visible today — a geological phenomenon found in only a few locations worldwide.
Can I use the observatory?
Yes — the observatory (equipped with a 14-inch telescope) hosts astronomy programs, often in partnership with the National Public Observatory. These include laser-guided tours of the cosmos. Programs are seasonal — check the park’s schedule for dates and times.
