When Does Ski Season Start? Regional Windows and 2026/27 Opening Dates
A region-by-region look at typical ski-season opening and closing windows, plus the specific 2026/27 opening dates that resorts and operators have officially published so far.
How this guide was built: Guidevio compiled it from resorts' and operators' own official season-dates pages, press releases and newsroom announcements. We did not visit these resorts as part of building it, and nothing here is a review or a personal-experience ranking. Opening and closing dates are targets that can shift earlier or later based on snowfall and snowmaking conditions; always check the official page linked below before planning a trip. Links go to official resort or operator pages and earn no commission today; if that changes, it will be disclosed here.
There's no single national "ski season start date" — each resort sets and publishes its own target opening day, and actual opening depends on natural snowfall and snowmaking conditions. This page summarizes typical opening and closing windows by US region, based on resorts' own season-date pages, plus the specific 2026/27 opening dates that resorts and operators have officially announced as of this research.
High-elevation, snowmaking-equipped Colorado areas like Arapahoe Basin, Loveland and Keystone have historically opened first, often in October, while Killington, Vermont is typically the first Eastern US resort to open, usually in mid-November. Washington's Crystal Mountain depends heavily on natural snowpack and has opened as late as mid-to-late December in slow-snow seasons. Resorts consistently caveat that published dates are "targets" or "planned" dates subject to change based on weather.
What was checked for each entry: the resort or operator's own official season-dates, press-release or newsroom page. Where a resort had not yet published a 2026/27 date at the time of this research, that is noted as "not published" rather than estimated.
Who this guide is for
- Skiers and riders planning trip dates around a resort's likely opening day
- Pass holders (Epic, Ikon) tracking announced 2026/27 opening dates
- Travelers deciding between Rocky Mountain, Northeast, Pacific Northwest or Sierra destinations based on typical season length
- Anyone wondering why ski season start dates vary so much resort to resort
How we chose
- Included only regions and resorts with a published official season-dates page, press release or newsroom announcement found during research
- Pulled opening/closing dates directly from resort or operator sources rather than third-party trackers, except where a resort's own page cites a historical average
- Noted 2026/27 dates exactly as announced, marking resorts that had not yet published a 2026/27 date as 'not published'
- Excluded any date not attributed to an official resort or operator source
- This is desk research only; Guidevio did not visit any resort to verify conditions

Colorado's season can span 4 to 7 months depending on the resort, per Vail's own travel guide

How the top picks actually differ
Why there's no single 'ski season start date'
Every resort in this guide sets and publishes its own target opening day, and that date depends on the resort's elevation, snowmaking capacity, and latitude. Colorado's high-elevation, snowmaking-equipped areas like Loveland, Arapahoe Basin and Keystone typically open first, often in October, while most other Colorado resorts open in November. There is no single, universal national ski-season start date; resorts describe their own published dates as 'target' or 'planned,' subject to change.
Regional patterns: Rockies, Northeast, Pacific Northwest, Sierra Nevada
Colorado's typical window runs mid-to-late November through early-to-mid April, spanning 4 to 7 months depending on the resort. The Northeast's earliest opener is historically Killington, Vermont, usually mid-November, with other major Vermont resorts (Stowe, Okemo, Mount Snow) typically opening about a week to ten days later. The Pacific Northwest (Washington) is the most snowpack-dependent region covered, with Crystal Mountain having opened as late as mid-to-late December in slow-snow seasons. The Sierra Nevada's Mammoth Mountain has the strongest published consistency, citing no opening later than November since 1986.
How the Epic Pass and Ikon Pass announcements differ for 2026/27
Vail Resorts (Epic Pass) published a staggered, multi-resort 2026/27 opening-date announcement on August 18, 2026, covering Colorado, Utah, California, Washington and British Columbia properties, with Northeast dates to follow later. Alterra Mountain Company's September 24, 2026 Ikon Pass announcement, by contrast, covered terrain expansions and pass pricing but did not include a consolidated list of individual resort opening dates, so Ikon Pass holders need to check each resort's own page directly.

Common questions
- When does ski season officially start?
- There is no single official national start date. Each resort sets and publishes its own target opening date based on elevation, snowmaking capacity and expected snowfall. High-elevation Colorado areas with snowmaking often open in October, while most other resorts open in November, and Pacific Northwest resorts dependent on natural snowpack can open as late as December.
- Which US resort typically opens first?
- Among the resorts covered here, high-elevation, snowmaking-equipped Colorado areas such as Arapahoe Basin, Loveland and Keystone have historically opened first, often in October. Loveland's own 10-year average opening date is October 27. In the East, Killington, Vermont is historically the first resort to open, typically in mid-November.
- What are the confirmed 2026/27 opening dates so far?
- As of this research, confirmed 2026/27 dates include: Keystone (CO) as soon as possible in October; Breckenridge (CO) November 6, 2026; Vail Mountain (CO) November 13, 2026; Whistler Blackcomb (BC), Park City Mountain (UT), Heavenly (CA) and Northstar (CA) November 20, 2026; Beaver Creek (CO) and Crested Butte (CO) November 25, 2026; Kirkwood (CA) and Stevens Pass (WA) December 4, 2026; and Big Sky Resort (MT) November 25, 2026. These are per Vail Resorts' and Big Sky's own official announcements.
- Has Ikon Pass published a 2026/27 opening-date list?
- Not a consolidated one. Alterra Mountain Company's September 24, 2026 Ikon Pass announcement covers new destinations and terrain expansions but does not list individual resort opening dates; Ikon Pass holders are directed to check each resort's own page.
- Why do resorts describe opening dates as 'targets'?
- Because actual opening depends on natural snowfall and snowmaking conditions. Resorts across every region in this guide, from Vail Resorts to Big Sky to Whistler Blackcomb, explicitly state that published opening dates are targets or planned dates 'subject to change based on weather and conditions.'
- How long does a typical ski season last?
- It varies by region. Colorado's typical season spans roughly 4 to 7 months, from mid-to-late November through early-to-mid April, with some resorts open into May. Big Sky Resort's published 2026-27 schedule runs from November 25, 2026 daily operations through April 11, 2027, plus two bonus spring weekends.
