Arapahoe Basin sits on the Continental Divide near Dillon and covers 1,428 acres (578 hectares) of high alpine terrain. The base is at 10,520 ft (3,206 m) and the summit tops out at 13,050 ft (3,977 m), a vertical drop of 2,530 ft (771 m) across 147 runs. The split leans steep, with 49% advanced, 24% expert, 20% intermediate and just 7% beginner, so green circle choice is thin. Average snowfall is around 350 inches a year, with the Lenawee Express carrying skiers to the top of the main peak.

The East Wall is the signature steep zone, a billboard of double black chutes off Lenawee Mountain, bisected by the long East Wall Traverse that reaches a lot of difficult terrain. Pallavicini is a group of steep, mogul-covered double black runs, with gated access to Steep Gullies, narrow, rocky, expert-only chutes that were backcountry before joining the ski area in 2017-18. Montezuma Bowl on the back side, served by the Zuma lift, offers everything from groomed intermediate runs to advanced cornice runs. A-Basin rewards confident advanced and expert skiers and solid intermediates who want open alpine terrain rather than tree-lined groomers. Newer skiers will find bigger beginner areas elsewhere in Summit County.

The 2025-26 season at Arapahoe Basin ran from 25 October 2025 to 14 June 2026, an exceptionally long roughly thirty-three-week season, among the longest in Colorado, supported by average annual snowfall of around 350 inches. This marketed longest season reflects the resort's considerable elevation and reliable early and late-season conditions.

Midwinter, from December through February, typically brings the most consistent conditions to A-Basin's advanced-and-expert-weighted terrain. As an Ikon Pass and Mountain Collective resort, A-Basin draws substantial visitation from pass holders alongside dedicated local skiers seeking its genuinely high-alpine character and famously late spring skiing season.

The resort's above-treeline terrain and Montezuma Bowl expansion continue to draw experienced skiers throughout the season, particularly during the extended spring period when few other Colorado resorts remain open. School holiday periods bring some family visitation, though the resort's advanced-weighted terrain skews its visitor base toward more experienced skiers.

Specific event programming beyond standard operations is not confirmed in available resort information. Since Dundee Resort Development's 1997 acquisition, A-Basin has continued building on nearly eight decades of history since its December 1946 founding as Colorado's first post-war ski area. The Legend's long season and high-alpine terrain remain central to its identity each year.
