Ikon Pass Blackout Dates for 2026/27
Ikon Base can look like the sensible purchase until the family’s one free week lands inside a holiday restriction. Full Ikon removes the standard blackouts in the main network. It does not turn every mountain into unlimited access, cancel a reservation requirement or erase the separate Bonus Mountain rules.
The holiday dates that change the decision.
This Northern Hemisphere calendar applies to Base, Session and the full pass’s separate Bonus Mountain benefit. It is not a blanket restriction on full Ikon’s main network.

13–14February holiday weekendWhat does upgrading from Base actually buy?
First decide whether the dates work. Then look at the mountains and day banks. The official access comparison treats those as separate questions; your purchase should too.
| Product / benefit | Blackout treatment | Days and access |
|---|---|---|
| Full Ikon — main network | No standard blackout dates. | 18 unlimited destinations, with up to seven days at other included destinations. Some allocations are shared. |
| Ikon Base | Northern dates above; Southern Hemisphere: July 4–19, 2026, and July 3–18, 2027. | 15 unlimited destinations; up to five days at many partners. Some premium mountains are excluded altogether. |
| Ikon Session | Northern dates above. | Two, three or four days total across eligible destinations, not that many at every mountain. |
The upgrade question
The extra access needs a job.
Five days can cover a trip comfortably. They are a different proposition at a mountain you expect to ski every weekend. Full Ikon can add usable dates, more days or a destination missing from Base. Which of those will you actually use?
If none of the extra access changes a real plan, a longer mountain list is not much of an argument. If school vacation fixes the dates, the calendar may decide the question before the list gets a vote.
A usable date is only half the answer.
Base does not include every full-pass destination, and five days at one mountain are not five days at every neighboring mountain. These are the distinctions most likely to change a trip.
| Destination / rule | Full Ikon | Base / Session distinction |
|---|---|---|
| Aspen Snowmass | Seven days shared across Aspen Mountain, Snowmass, Aspen Highlands and Buttermilk. | Base: five Snowmass-only days with blackouts. Session does not include Aspen Snowmass. |
| Alta / Snowbird | Seven days shared between the two. | Base: five Snowbird-only days with blackouts. Session does not include Alta or Snowbird. |
| Crystal Mountain, Schweitzer, Steamboat | Unlimited. | Base: five days each with blackouts; Session uses its total purchased day bank. |
| Deer Valley, Jackson Hole, Sun Valley, Snowbasin | Seven days each, subject to destination rules. | Not included on Base or Session. This is an exclusion, not merely a holiday blackout. |
| Reservations | The operator names Jackson Hole, Deer Valley and Loon for 2026/27. | Required where your product includes the destination; a reservation does not grant an excluded mountain or override a blackout. |
| Southern Hemisphere | Included destination allowances are subject to the applicable 2026 / 2027 season terms. | Base has separate July restrictions; do not apply a North American winter calendar worldwide. |
Put the upgrade beside a real trip.
Christmas with the family
If the only ski trip falls December 26–30, Base’s standard restriction matters. Full Ikon may solve the date problem in its main network. It does not solve it at a Bonus Mountain, where that same holiday block still applies.
The Snowmass week
Outside the blackout dates, Base provides five Snowmass-only days. Full Ikon provides seven shared days across the four Aspen Snowmass mountains. Decide whether the other mountains and extra days belong in the trip before treating the upgrade as necessary.
A shorter winter
A four-day Session Pass is four days total across its eligible destinations. It is not four days per resort, and it keeps the standard Northern Hemisphere holiday exclusions. Count the season honestly before choosing a day bank.
The useful exceptions.
Bonus Mountains and Southern Hemisphere access
| Product / benefit | Blackout treatment | Days and access |
|---|---|---|
| Full Ikon — Bonus Mountains | Northern dates above, despite the main pass’s no-blackout description. | Two days each at 11 separate Bonus Mountains. No lift reservations required for this benefit; redemption method varies. |
The 11 Bonus Mountains are Tamarack, Snowy Range, Jiminy Peak, Ski Butternut, Buck Hill, Giants Ridge, Wild Mountain, Cranmore, Devil’s Head, Caberfae Peaks and Grouse Mountain. Each offers two days on the full 2026/27 Ikon Pass, with the Northern Hemisphere dates above excluded.
Grouse Mountain, Giants Ridge, Tamarack and Snowy Range offer direct-to-lift access for this benefit; the others require window check-in. These days do not consume the main network’s seven-day allowances. Check the destination’s instructions before arriving.
Base’s separate Southern Hemisphere restrictions are July 4–19, 2026, and July 3–18, 2027. Keep the applicable season and destination allocation in view rather than carrying a North American holiday calendar around the world.
The operator’s how-to-use guide explains Bonus Mountain check-in and current reservation requirements.
A couple of questions before booking.
Does December 31 belong to the standard holiday blackout?
No. The published Northern Hemisphere block ends December 30, 2026. That does not guarantee an available reservation or operating conditions at your destination. Check the Base date guidance against the destination’s own instructions.
Does a reservation override a blackout or an excluded resort?
No. Reservations are a separate entry condition where required. They do not add a mountain to your product or make an excluded date usable. For 2026/27, the operator identifies Jackson Hole, Deer Valley and Loon as requiring lift reservations.
Keep the comparison close to your winter.
The Ikon review covers the wider season; Full vs. Base puts the tiers beside each other. For another calendar, read the Epic guide or explore regional alternatives. Extra access earns its keep when it changes a day you will actually ski.
