Skiing Aspen Snowmass, told properly
Aspen was a silver-mining boomtown of 1880s opera houses and grand hotels before the crash of 1893 nearly emptied it — then skiing arrived after World War II, when 10th Mountain Division veterans returned to the valleys they'd trained in. Aspen Mountain opened in 1946 with what was then the world's longest chairlift, and the town reinvented itself as America's definitive ski resort: equal parts athletic, intellectual and glamorous, home to the Aspen Institute and a music festival as famous as its moguls.
The skiing spreads across four distinct mountains on one pass. Aspen Mountain (Ajax) rises straight from downtown with relentless expert terrain and zero green runs; Aspen Highlands is the connoisseur's hill, crowned by the hike-to Highland Bowl at 12,392 ft; Buttermilk is the gentle learning mountain that doubles, improbably, as the permanent home of the Winter X Games; and Snowmass is the giant, with more than 4,400 ft of vertical and terrain for every human alive.
Après ranges from champagne on sun decks to dive-bar shot-and-beer — often on the same block. No American resort mixes high and low culture with such confidence.
Signature runs
Highland Bowl
A 30–45 minute ridge hike from the top lift opens 270 acres of steep, perfect pitch — the best inbounds bowl in Colorado.
Walsh's (Aspen Mountain)
Ajax's signature double-black shot toward the valley — steep, fast and in full view of the gondola.
Hanging Valley Wall (Snowmass)
Snowmass's wild side — cliffs, glades and powder stashes far from the groomer highways.
Big Burn (Snowmass)
A vast, open intermediate face born of an 1879 forest fire — cruising at its most expansive.
Local tips
- Free snowcat tows run to Highland Bowl's gate on busy days — save your legs for the descent.
- Ride the Silver Queen Gondola at Ajax and ski the Ridge of Bell moguls when the sun softens them mid-morning.
- Buttermilk in January = X Games; go watch the superpipe finals free under the lights.
- The Highlands' Cloud Nine cabin lunch is legendary — and legendarily rowdy by 2 pm; book the early seating.
Good to know
- Aspen Mountain opened in 1946 with Lift-1, then the longest chairlift in the world.
- Buttermilk has hosted the Winter X Games every year since 2002 — the longest X Games residency ever.
- Aspen's 1880s silver mines briefly made it one of the richest towns in the American West before the 1893 crash.
