Arapahoe Basin Ski Resort
Colorado’s Highest and Longest Season — Where Expert Skiers Come to Play
About Arapahoe Basin
Arapahoe Basin — universally known as A-Basin — is one of the most beloved ski areas in North America. Sitting at an average elevation of over 12,000 feet in the Colorado Rockies near Keystone, it consistently opens among the first resorts in the US and often stays open into June, giving it one of the longest ski seasons on the continent.
What sets A-Basin apart isn’t glitz or massive resort infrastructure — it’s the skiing. Roughly 50% of terrain is rated black diamond or double black, and the above-treeline bowls attract serious skiers from across the country. The mountain’s raw, alpine character has earned it a devoted following who prize challenge over convenience.
A-Basin left the Ikon Pass in 2019 and now operates independently, which means lower crowds compared to mega-resorts and a refreshingly old-school atmosphere. The famous “Beach” — a sloped parking lot that transforms into a tailgate party on sunny spring afternoons — has become as legendary as the skiing itself.
Terrain Overview
The mountain’s terrain breakdown tells the story: 10% beginner, 40% intermediate, 50% advanced and expert. While there are gentle runs for novices learning the sport, A-Basin is fundamentally an expert mountain.
The Pallavicini Face is A-Basin’s signature run — a steep, sustained 2,000-foot drop that demands precision and commands respect. Montezuma Bowl, the resort’s signature above-treeline area, offers 900 acres of open bowl skiing with commanding views of the Continental Divide. The Beavers and The Steep Gullies provide some of the most committing terrain at any Colorado resort.
Intermediate skiers aren’t forgotten — trails like Wrangler and Columbine offer long, satisfying cruisers. But the mountain’s heart belongs to those who want to push limits at altitude.
Off-piste enthusiasts will find excellent opportunities in Montezuma Bowl and the East Wall, where variable snow conditions and natural features create a genuine backcountry feel within resort boundaries.
Snow & Conditions
Arapahoe Basin’s high elevation is its snow guarantee. The resort averages around 350 inches (889 cm) of snow annually, and the cold, dry Colorado air preserves powder exceptionally well. Early season snowpack builds quickly at this altitude, which is why A-Basin routinely opens in late October or early November when lower-elevation resorts are still waiting.
Spring skiing here is a Colorado institution. By May, the days are long, temperatures are warm at midday, and the notorious “corn snow” — a heavy, recrystallized spring snow — makes for fast, grippy conditions. The Beach comes alive with picnics, costumes, and live music. Skiing into June at 13,000 feet is a quintessentially A-Basin experience.
Who Is Arapahoe Basin For?
Expert skiers and riders should put A-Basin at the top of their Colorado list. The combination of high elevation, steep sustained pitches, and genuine alpine terrain makes it a standout. If you’ve skied everything at bigger resorts and want a real challenge, this is your mountain.
Intermediate skiers will find enough blue terrain to have a great week, especially in the morning before venturing onto steeper runs. The lower mountain provides a good confidence-building base.
Beginners can learn here but may feel somewhat out of place — the culture and terrain tilt heavily toward experienced skiers. Nearby Keystone or Breckenridge offer more beginner-focused infrastructure.
Budget-conscious skiers will appreciate A-Basin’s independent pricing, which is notably lower than nearby Vail Resorts properties, and the resort’s parking-lot culture eliminates the need for expensive lodging at the mountain’s base.
Top Runs & Highlights
- Pallavicini — The resort’s most iconic run. A relentlessly steep face with no easy exit. One of the best blacks in Colorado.
- Montezuma Bowl — 900 acres of above-treeline bowl skiing. Wide open, wind-affected, and spectacularly scenic.
- East Wall — Expert-only terrain with several steep chutes and rock bands accessed from the Zuma Lift.
- Wrangler — A long, satisfying intermediate cruise from the summit ridge. Great for building confidence or warming up.
- The Beavers — A collection of black diamond runs off the Lenawee lift, consistently holding good snow due to their north-facing aspect.
- The Beach — Not a ski run but an experience. Spring afternoons here are a Colorado tradition.
Ski Lessons & Activities
A-Basin offers ski and snowboard school programs for all levels, with a particular emphasis on helping intermediate skiers progress to steeper terrain. The resort is not a major après-ski destination, but several recommended ski lessons and guided tours of the more challenging terrain are available.

Frequently Asked Questions — Arapahoe Basin
Is Arapahoe Basin on the Ikon Pass?
No. A-Basin left the Ikon Pass network in 2019 and operates independently. They offer their own season pass (the A-Basin Mountain Collective Pass) and day tickets. Their independent status often results in better value and lower crowds compared to Ikon or Epic Pass resorts.
When does Arapahoe Basin open and close?
A-Basin typically opens in late October or early November — often among the first resorts in Colorado — and stays open until June, occasionally into early July. The exact dates depend on snowfall, but the resort consistently has one of the longest seasons in North America thanks to its extreme elevation.
Is Arapahoe Basin good for beginners?
A-Basin has beginner terrain, but it’s not the ideal resort for first-timers. The high altitude (10,780 ft base) can be tough for those not acclimatized, and the mountain’s culture and terrain tilt heavily toward experienced skiers. Nearby Keystone or Breckenridge offer much better beginner infrastructure.
What is “The Beach” at Arapahoe Basin?
The Beach is the sloped parking lot at A-Basin’s base that transforms into a legendary spring tailgating scene. On warm sunny days from March onward, skiers set up grills, lawn chairs, and umbrellas after their morning runs and enjoy the Colorado sunshine. It’s a beloved tradition unique to A-Basin.
How does A-Basin compare to nearby Breckenridge or Keystone?
A-Basin offers more challenging terrain and a rawer, less polished atmosphere than either Breckenridge or Keystone. It has far less amenity infrastructure (no village, minimal base lodges), which is part of its appeal to serious skiers. For après-ski, dining, and family amenities, Breckenridge wins easily. For pure skiing and expert terrain at altitude, A-Basin is the choice.
Can you ski A-Basin in late May or June?
Yes — and it’s highly recommended. Late-season skiing at A-Basin is a Colorado institution. Montezuma Bowl and the upper mountain typically hold snow into June. Warm days, long afternoons, and the Beach scene make late spring one of the most enjoyable times to visit.
