Which two of the four mountains are actually yours?
Two, and the choice is made by who is travelling, not by the map. One lift pass covers all four and a shuttle connects them, so the only real question is which two deserve your days. Ajax rises straight out of town and has no beginner terrain at all — short, steep, and walkable home from dinner. Highlands is where strong skiers go for the hike-to bowl. Buttermilk is the gentlest and the reason families base here. Snowmass has the vertical, from a base at 8,104 feet (2,470 m) to 12,510 feet (3,810 m), and the ski-in residences. We put a family on the right two and skip the other two entirely.
When to come, and what each month costs you?
The 2026–27 season runs 26 November 2026 to 18 April 2027. January holds the driest snow and the fewest people once the New Year week clears. February is the most reliable. March buys longer days, softer afternoons and better value, at the price of variable conditions. The two weeks around Christmas and New Year are the hardest booking in North America — residences go a year ahead, and we start that conversation in the previous winter, not the previous autumn.
The thing nobody has told you yet: the airport closes in 2027
Aspen/Pitkin County Airport shuts from 11pm on Sunday 4 April 2027 until 7pm on Friday 19 November 2027, for a full runway reconstruction and the start of a new terminal. No commercial flights, no general aviation, no private jets, no access to the terminal — for seven and a half months. Two consequences follow. The last two weeks of the ski season, 4 to 18 April 2027, are reached by road from a regional airport rather than by flying into town. And the whole of summer 2027 is a driving destination. We are already planning 2027 trips against Eagle County and the longer transfer, and anyone who books Aspen for those dates without knowing this will find out at the worst moment.
Does the pass in your pocket still work here?
It depends which one. The full Ikon Pass is unchanged: seven days across all four mountains. The Ikon Base Pass changes for 2026–27 — five days at Snowmass only, with blackouts on 26 to 30 December, 16 and 17 January 2027 and 13 and 14 February 2027. No lift reservations are required at any of the four mountains for either pass. If your party is holding Base passes and expecting Ajax, that is worth knowing before the flights are booked.
Is Aspen worth a summer trip?
Yes, and it is a different trip at a fraction of the winter price. The Aspen Music Festival runs 30 June to 22 August 2027. The Maroon Bells are the other reason, and they are rationed: trailhead parking runs 15 May to 31 October, the shuttle from Aspen Highlands 22 May to 18 October, and the scenic area is closed to inbound private vehicles between 8am and 5pm, so the Bells are an early-morning or late-afternoon proposition and reservations are mandatory. Note that summer 2027 falls entirely inside the airport closure.
Who is Aspen wrong for?
A beginner put on Ajax, and anyone who arrives and skis hard on day one. The town sits at 7,908 feet (2,411 m) and the lifts go above 12,000 — we plan a gentler first day and hydration rather than pretending altitude is a personality flaw. A car is also usually a liability here: the town is walkable, the inter-mountain shuttle works, and we arrange transfers instead.
