Keystone

Keystone's summit reaches 12,408 feet, dropping 3,128 vertical feet to a base at 9,280 feet across 128 runs spread over 3,148 acres near Dillon, Colorado. Terrain splits 41 per cent intermediate, 21 per cent each for advanced and beginner, and 17 per cent expert, with average annual snowfall of roughly 235 inches. The resort carries Epic Pass affiliation. Twenty lifts, including seven quad chairs and one gondola, serve the mountain alongside six six-person chairs, one triple chair and five surface lifts.

Keystone holds a distinctive place among Colorado resorts as one of the few offering extensive night skiing, alongside three distinct mountains, Keystone, North Peak and the Outback, that give the resort considerable terrain variety across a single connected area. This combination of night skiing and varied terrain has built Keystone's reputation as a genuinely family-friendly, accessible major resort.

Ketchum, Colorado was renamed Montezuma in 1867 following the discovery of silver in the area, and mining activity continued in the region for decades. Ralston Purina purchased land and developed Keystone Resort, which opened in 1970 as a purpose-built ski destination rather than a converted mining town. The resort expanded considerably over subsequent decades, adding North Peak in 1978 and the Outback in 1999.

Vail Resorts purchased Keystone alongside Breckenridge in 1996 from Ralston Purina's Ralston Resorts subsidiary, bringing both resorts into what would become the Epic Pass network. Adult daily tickets run from 129 to 209 US dollars.
