Below: the dates that matter, organized by month — with category color codes so you can scan by what you care about.

Book the room before the ticket.

· How to plan the trip ·

The peak weeks, ranked.

Week 1 · Most expensive
Food & Wine + JAS June overlap.
June 19–28. Food & Wine the first weekend, JAS June starting Thursday after. Hotel rates roughly triple. Restaurants book six weeks out.
Week 2 · Hardest to book
Aspen Ideas Festival.
June 22 (Health) through July 1. Aspen Institute campus packed; downtown lodgings sold out. Lock in lodging through their preferred-rate program by May.
Week 3 · Highest priced
JAS Labor Day Weekend.
Sept 4–6. The single most expensive lodging weekend of summer in Snowmass; Aspen hotels nearly as tight. Book by March.
Week 4 · Best value
Post–Labor Day, pre-Balloon.
Sept 7–24. The two-and-a-half-week window when rates drop, restaurants take reservations easily, and aspens start to turn. The locals' favorite week.
· After the Festivals ·

The most beautiful weeks come after Labor Day.

If you can afford a non-festival visit, the two weeks after the JAS Labor Day weekend are when the aspens turn gold, the lifts at Maroon Creek scenic gondola open for fall foliage, and the dining rooms become reservable again. The town quiets down for a brief window before the ski-season pre-opening prep begins.
