Colorado Ski Resorts Opening Days 2025 Announced

As summer winds down and fall begins to ramp up in the mountains, it’s time to start dreaming of snowy mornings, crisp runs, and fresh turns. Here’s what you need to know about the resorts closest to Base Mountain Sports—plus what the early-season can look like for the upcoming 2024-25 ski season.
Opening day schedules for Colorado ski resorts are typically announced in Aug, with most opening days scheduled for late fall.

Opening Dates to Circle on Your Calendar

Here are the projected opening days for key Colorado ski resorts:

• Keystone: TBD - Shooting for Mid October.*
• Arapahoe Basin: Nov 2, 2025
• Breckenridge: Nov 7, 2025 (Breckenridge's opening day falls on a Friday this year)
• Vail: Nov 14, 2025
• Beaver Creek: Nov 26, 2025

*These dates are subject to change based on weather conditions, so keep an eye on official announcements as conditions evolve.

What to Expect on Opening Day: Terrain Coverage & Conditions

Although early-season terrain availability varies year-to-year, historical trends provide some insight. Around the holidays (think December 25), resorts like Beaver Creek and Vail typically have excellent coverage for skiing and riding:

Resort	Avg. Terrain Open by Dec 25	Chance < 50% Open
Beaver Creek	~80%	~15%
Vail	~83%	~15%

Arapahoe Basin’s high elevation and aggressive snowmaking often help it open early (even mid‑October historically), though terrain coverage at first chair will be more limited—expect mostly lower-mid mountain runs initially for skiing and riding. The two resorts, Keystone and Arapahoe Basin, often open together, offering some of the earliest skiing and riding in Summit County.

Early November openings at Keystone and Breckenridge tend to come with modest coverage—primarily groomed beginner to intermediate terrain supported by snowmaking—but full mountain access is developed rapidly as natural snowfall accumulates. Terrain and activities continue to expand as more snow falls.

Winter 2025–2026 Weather & Snow Outlook

Here’s what the seasonal forecasts are saying:

• NOAA & SKI Magazine anticipate average snowfall across central and northern Colorado this season
• According to SnowBrains’ interpretation of NOAA, an early trend resembling La Niña may bring above-average precipitation (snow) to the Northern Rockies—including parts of Colorado—during November–January .
• The Farmers’ Almanac projects a very cold and snowy winter for Colorado

Daily snow and weather updates will be available throughout the season to keep you informed.

While forecasts lean toward at-least-normal or above-normal snow, keep in mind that seasonal outlooks are probabilistic, and micro-weather patterns can shift. Weather trends will clarify through fall, so keep your winter gear ready for action.

Look for the debut of new resort offerings and improvements for the upcoming season.

Staying Safe on the Slopes Early Season

As the winter season approaches and Colorado’s iconic ski resorts prepare to welcome guests, safety remains a top priority at all ski resorts. Whether you’re gearing up for your first time on the mountain or you’re a seasoned rider eager for opening day, taking a few simple precautions can make all the difference in ensuring a fun and memorable experience.

Before you hit the slopes, be sure to check the latest updates on the resort’s website. Most resorts provide real-time information on terrain access, snow conditions, and any special safety guidelines in place for opening days. This is especially important in October and November, when early-season conditions can change quickly.

Respect the mountain and fellow skiers/riders, especially on busy days like opening day when everyone is stoked to catch the first chair. Follow all posted signs, pay attention to chairlift instructions, and be patient in lift lines. Remember, the early season often means limited terrain, so sharing the slopes courteously helps everyone enjoy their day. And always ski or ride within your ability level to avoid unnecessary risks.

As you plan your visit—whether it’s your first time or you’re returning for another killer season—keep safety top of mind. For the latest updates on opening days, terrain, and safety guidelines, be sure to visit your favorite resort’s website before heading out. Cheers to a safe, snowy, and unforgettable winter in Colorado!
