Arapahoe Basin: Arapahoe Basin, usually called A-Basin (or even just the Basin), is located in the White River National Forest high up in the Rocky Mountains. Known for its especially long season and hard-core clientele, A-Basin has some incredible terrain for advanced skiers. Add to that an incredible 350 inches of annual snowfall, it’s no wonder why this a top destination for those who like it steep. A-Basin is not glamorous like many other Colorado resorts – and that is the appeal for many. The East Wall is widely regarded as the highest inbounds skiable terrain in North America. The resort provides 900 skiable acres served by seven lifts.
