Pajarito Mountain's summit reaches 10,440 feet, dropping 1,441 vertical feet to a base at 8,999 feet across 45 runs spread over 750 acres near Los Alamos, New Mexico. Terrain splits 50 per cent intermediate, 30 per cent advanced and 20 per cent beginner, with no expert-rated runs, and average annual snowfall of roughly 165 inches. The resort offers Power Pass access. Five lifts, including three double chairs and one quad chair, serve the mountain alongside one surface lift.

Pajarito carries an unusual scientific pedigree: the ski area traces directly back to the Manhattan Project scientists and soldiers stationed at nearby Los Alamos during the Second World War. This origin gives the resort a distinctive place in ski history among New Mexico's mountains, alongside its more conventional identity today as a community-run, volunteer-supported ski area. Its terrain mix, weighted toward intermediate and advanced skiing, suits a broad range of visitors.

In 1943, Los Alamos scientists and soldiers, many of whom had grown up skiing in the Alps, formed the Los Alamos Ski Club, with early members including Nobel laureates Enrico Fermi and Emilio Segrè, along with J. Robert Oppenheimer. The club first opened a modest ski hill at Sawyers Hill in December 1944, charging 7.50 US dollars a person for access to a single tow rope. As snow on Sawyers Hill grew unreliable, the club identified Pajarito Mountain as offering steeper runs, more terrain and more consistent snow.

On 23 November 1957, the volunteer-built Pajarito Mountain ski area opened with two tows, double the vertical drop of Sawyers Hill, a beginner's slope and a narrow upper trail. Investor James Coleman acquired the ski area in 2014 in partnership with Los Alamos County, and the resort joined Mountain Capital Partners in 2018, combining continued volunteer involvement with professional management. Adult daily tickets run from 45 to 65 US dollars, with the Power Pass from 399 dollars.
