Summit County, Colorado
Arapahoe Basin Ski Area
Arapahoe Basin, usually called A-Basin, is a high-alpine Colorado mountain with a strong advanced-terrain identity. The resort presents its mountain as seven distinct areas, rather than one interchangeable set of runs.
- High-alpine mountain
- Seven terrain areas
- Pallavicini and East Wall
Terrain and ability at A-Basin
Pallavicini, the East Wall and the Steep Gullies are named parts of A-Basin's terrain story. The field guide also separates beginner, intermediate and expert planning resources. Use the current map and terrain status to choose an appropriate area before following a friend uphill.
Arrival, bases and lessons
Read the resort's directions, parking and transit guidance for your actual date. Parking rules and available terrain change through the season; an early- or late-season visit should be planned from the current report.
Plan a A-Basin meetup
Pick a public base-area landmark and agree on whether the day is for groomers or more demanding terrain. The Beach is a named part of A-Basin's base culture, but your invitation should still identify an exact meeting location.
Use the meetup message planner to agree on your date, terrain, pace and meeting point.
