When Does Ski Season End in Colorado?

By Sarah Miller · June 7, 2053

Colorado ski season typically ends between mid-April and early June, depending on the resort, snowfall, and elevation. Resorts at higher altitudes like Arapahoe Basin often operate into June, while lower-elevation areas such as Aspen Snowmass usually close by late April.

Factors That Determine When Ski Season Ends in Colorado

The end of ski season in Colorado isn't fixed—it varies significantly across resorts due to several key factors:

Elevation: Higher-altitude resorts retain snow longer, allowing for extended operations.
Snowfall totals: A heavy winter snowpack can push closing dates later into spring.
Weather conditions: Warm temperatures and sunny skies accelerate melting, especially at lower elevations.
Resort operations: Some resorts prioritize terrain parks or specific runs for spring skiing.
Spring break crowds: Many resorts extend operations to accommodate spring vacationers.

Top Colorado Resorts and Their Typical Closing Dates

While exact closing dates change annually based on conditions, most resorts follow predictable patterns. Below is a table showing average end-of-season dates for major Colorado ski areas.

Resort	Average Closing Date	Highest Elevation (ft)	Base Elevation (ft)	Vertical Drop (ft)
Arapahoe Basin	Early June	13,050	10,780	2,270
Keystone Resort	Early May	12,408	9,280	3,128
Breckenridge Ski Resort	Mid-May	12,998	9,600	3,398
Vail Mountain	Early May	12,713	8,120	4,593
Winter Park Resort	Mid-April	12,060	9,000	3,060
Aspen Snowmass	Mid-April	12,510	8,040	4,470
Steamboat Resort	Early April	10,568	6,900	3,668
Crested Butte Mountain Resort	Early May	12,162	8,895	3,362

The data shows a clear correlation between elevation and season length: resorts above 12,000 feet, like Arapahoe Basin and Breckenridge, consistently operate into May or beyond. In contrast, lower-elevation resorts such as Steamboat and Aspen Snowmass typically conclude operations in April due to faster snowmelt. Arapahoe Basin’s high base elevation and north-facing terrain allow it to remain open well into June during favorable years.

Extended Seasons: Why Some Resorts Stay Open Longer

Not all Colorado ski areas shut down at the same time. The longest-running resorts have strategic advantages:

High base elevation: Above 10,000 feet, snowpack remains stable even with warming trends.
Northern exposure: North- and east-facing slopes receive less direct sunlight, slowing melt rates.
Spring operations focus: Resorts like Keystone and Breckenridge maintain select lifts and terrain parks for spring skiers.
Passholder incentives: Extended weekends encourage loyalty and repeat visits.

Arapahoe Basin: Colorado's Longest Ski Season

Arapahoe Basin, affectionately known as “A-Basin,” holds the title for the longest ski season in Colorado. It frequently operates from October through June, making it one of the few U.S. resorts to offer skiing in six months of the year. Its Eagle Wind chairlift services high-alpine bowls that stay cold and snowy long after other resorts have closed.

Spring Skiing Tips for Late-Season Visitors

If you're planning to ski in Colorado in April or May, consider these expert tips:

Ski early in the day: Morning snow is firmer and more enjoyable than afternoon slush.
Dress in layers: Temperatures fluctuate widely in spring—be ready for sun, wind, and cold mornings.
Check resort status daily: Terrain closures increase as the season winds down.
Look for deals: Spring lift tickets are often discounted, and lodging prices drop.
Enjoy après-ski events: Many resorts host festivals and pond skims in their final weeks.

Frequently Asked Questions About Colorado Ski Season End Dates

When does ski season usually end in Colorado?

Ski season in Colorado generally ends between mid-April and early June. Most resorts close by late April, but high-elevation areas like Arapahoe Basin and Breckenridge often operate into May or even June, depending on snow conditions.

Which Colorado ski resort stays open the longest?

Arapahoe Basin is renowned for having the longest ski season in Colorado, often staying open from October through June. Its high elevation and efficient snowmaking allow it to maintain operations long after other resorts have closed.

Can you still ski in Colorado in May?

Yes, you can ski in Colorado in May at select high-elevation resorts. Breckenridge, Keystone, and especially Arapahoe Basin regularly operate into May, offering spring skiing conditions with limited terrain and weekend-only lift service toward the end.

Does Vail stay open until May?

Vail Mountain typically closes in early May, often around Memorial Day weekend. While not as long as Arapahoe Basin, Vail extends its season into May most years thanks to its vast terrain and high elevation on the back bowls.

What affects the end date of ski season in Colorado?

The end of ski season depends on snowpack levels, spring temperatures, elevation, and resort operational decisions. Heavy snow winters delay closure, while warm, sunny springs accelerate melting, particularly at lower-elevation resorts.
