This mountain is perhaps best known as the home of Pajarito Mountain Ski Area, which has occupied the mountain's northern slopes since 1957. Lift service is offered to mountain bikers and hikers on select weekends during the summer. In addition to skiing and mountain biking, Pajarito Mountain is also very well-suited for hikers, snowshoers, and cross-country skiers. When the ski area is open (typically mid-December through late March), it operates only on Fri/Sat/Sun plus holidays, and thus its slopes are largely empty during the work-week.

Like the rest of the Jemez Mountains, Pajarito Mountain is volcanic in origin. It is a part of the eroded rim of a large ancient caldera, the Valles Caldera, which is now a national preserve.

The word "pajarito" means "little bird."

Getting There

You can reach Pajarito Mountain from the west via NM State Routes 4 & 501, or from the east via NM State Route 502. The large parking area at the base (~9200') of the Pajarito Mountain Ski Area is about 5 miles driving from the town of Los Alamos. Please click here for a map with directions.

Red Tape

Pajarito Mountain is on private land owned by the Los Alamos Ski Club (which owns and operates the ski area), but it is surrounded by public lands: the Valles Caldera National Preserve (to the west) and the Santa Fe National Forest (to the north, east, and south). The Los Alamos Ski Club allows public recreational access; however, please click here for some suggestions to keep everyone involved happy and safe. Access from the west via the Valles Caldera National Preserve is restricted; please visit their website for more information.


The closest camping is at Camp May Campground (~9300'), which is a very short distance up a dirt road to the NW of the ski area parking lot. Typically, the campground closes around Nov. 1 of each year and re-opens in the spring. Camping is by permit only, which can be obtained at the Larry Walkup Aquatic Center on Canyon Road in Los Alamos. Call 505-662-8170 for permit information. The next closest camping is at Bandelier National Monument (about 10-15 miles away). Please click here for more information.

Children refers to the set of objects that logically fall under a given object. For example, the Aconcagua mountain page is a child of the 'Aconcagua Group' and the 'Seven Summits.' The Aconcagua mountain itself has many routes, photos, and trip reports as children.
