Organ Mountains-Desert Peaks — Dripping Springs, Aguirre Spring & the La Cueva Trails
An hour northwest of El Paso, the Organ Mountains rise in a jagged wall of granite needles above the Mesilla Valley — a serrated skyline that gives the range its name and forms the heart of the Organ Mountains-Desert Peaks National Monument near Las Cruces. This day trades the interstate for a pair of trailheads on opposite flanks of the range: the western slope at Dripping Springs, where a spring-fed canyon shelters the ruins of a Gilded Age resort and a tuberculosis sanatorium, and the eastern slope at Aguirre Spring, where the La Cueva and Pine Tree trails climb into the cool shadow of the needles themselves. In between lies a landscape of ocotillo-studded bajada, historic rock caves, and long views across the Tularosa and Mesilla basins. The trails are moderate but exposed, the elevation runs 5,500 feet and up, and afternoon thunderstorms build fast in monsoon season — carry more water than you think you need.
