Arapahoe Basin (A-Basin), Colorado: The Legend — Longest Season, Highest Base

One of the highest, steepest, longest-running ski areas in North America — no-frills, core-skier "A-Basin" is a Summit County institution on the Ikon Pass.

The short version: Arapahoe Basin — "A-Basin," or just "The Legend" — is one of the highest, steepest, and longest-running ski areas in North America. Its base sits near 10,780 feet (among the highest anywhere), it often skis October into June, and it’s gloriously no-frills: raw terrain, tailgating at "The Beach," and none of the resort glitz. It’s on the Ikon Pass, about 15 minutes from Dillon.

Every Summit County resort has its personality, and A-Basin’s is the purest: it’s a skier’s mountain, unpretentious and a little wild, where the terrain is steep, the season is endless, and the après happens in the parking lot. If Vail is the polished resort, A-Basin is the soul of Colorado skiing.

The longest season around

Perched on the Continental Divide at one of the highest base elevations in North America, A-Basin holds snow when everywhere else has melted. It regularly opens in October and keeps spinning lifts into June — occasionally July — making spring and even summer laps a Colorado rite of passage.

The terrain & the vibe

A-Basin punches far above its size on steepness. The East Wall, Pallavicini (“Pali”), and hike-to chutes and bowls are the stuff of legend, some requiring avalanche gear and know-how. There’s approachable beginner and intermediate terrain too, but the culture is core: raw, friendly, and famously centered on The Beach, the slopeside tailgate scene right by the lot.

On Ikon & getting there

A-Basin is on the Ikon Pass and also sells day tickets. It sits on US-6 just over Loveland Pass from I-70, about 15–20 minutes from Dillon and Keystone — base there or in Frisco, since the mountain has little lodging of its own.

Arapahoe Basin FAQ

Is Arapahoe Basin on the Epic or Ikon pass?

Arapahoe Basin is on the Ikon Pass (it left the Epic Pass a few seasons back). You can also buy day tickets and its own pass. See our Epic vs. Ikon guide.

Does A-Basin really have the longest ski season in Colorado?

Usually, yes — thanks to its very high elevation, A-Basin often opens in October and stays open into June, sometimes July, one of the longest lift-served seasons in North America. Late-season spring skiing here is a Colorado tradition.

How high is Arapahoe Basin?

Its base sits around 10,780 feet — among the highest base areas in North America — and it tops out above 13,000 feet. That elevation is why the snow lasts so long, and why you should take the altitude seriously.

Is A-Basin good for beginners or experts?

Both, but it’s beloved by experts — the East Wall, Pallavicini, and hike-to steeps are legendary, some requiring an avalanche beacon. There’s solid beginner and intermediate terrain too, but A-Basin’s reputation is steep, raw, and no-frills.

Where do you stay to ski A-Basin?

A-Basin is essentially a day area with minimal on-site lodging, so most skiers base in Dillon, Keystone, or Frisco, all about 15–20 minutes away. See our where to stay guide.

What is "The Beach" at A-Basin?

The Beach is A-Basin’s famous slopeside parking-lot tailgating scene — grills, lawn chairs, and après right where you park. It’s a big part of the mountain’s laid-back, core-skier culture, especially in spring.
