Arapahoe Basin is mostly known for advanced and expert terrain, but also has runs for the novice and intermediate skier, as well as a children's program. The Black Mountain Express, Molly Hogan, and Molly's Magic Carpet lifts service easy runs. The Molly Hogan is a slow lift running over the bunny slope, for use by those just learning to ski. Black Mountain Express services greens, blues, and four blacks: one named for the lift, The Gulch which runs parallel to Black Mountain Express, "Lower Standard", and "Lower International" which can be accessed from the standard race traverse.
The Exhibition run features bumps, steep terrain, and a fair number of jumps. The Pallavicini lift services mostly black and double black terrain on the west side of the mountain, though it is possible to take some difficult blues back to the base. The Pallavicini face itself, a group of very steep and seemingly endless mogul runs, is rated double black diamond extreme. The Lenawee and Norway lifts take skiers to the top of the mountain, where they can access blues, blacks, and the East Wall. Opposite of the East Wall there is a blue called Cornice Run where skiers can take leaps from windblown cornices, though sometimes visibility can be a deterrent. Arapahoe Basin opened Zuma lift during the 2007–2008 season, which services blue, black and double black trails over the backside of Arapahoe Basin in Montezuma Bowl. The largest terrain expansion in the nation for the 2007–2008 season marks an 80% increase in terrain for Arapahoe Basin. Montezuma Bowl offers everything from groomed intermediate runs to advanced cornice runs.
The East Wall contains the most difficult terrain at Arapahoe Basin. The Lower East Wall is rated black diamond and can be reached without hiking. Open primarily in late winter and spring, the Upper East Wall is rated double black diamond extreme and is only accessible on foot. A hike of approximately 30 minutes will take you to the North Pole, a very steep descent through rocky terrain over avalanche-blasted territory. Along the ridge prior to the North Pole is a group of chutes accessed through notches in the cliff band. One chute actually requires some rock downclimbing to reach skiable snow, an interesting experience in ski boots while holding a pair of skis. These chutes are often only a couple of ski widths wide and require mountaineering skiing ability. Most of the terrain is prone to avalanches and is regularly blasted by the ski patrol before they declare the wall open. The Lower and Upper East Wall is bisected by the East Wall Traverse which is quite long and accesses a lot of difficult-to-reach territory from above and below, leaving prime snow conditions available for those willing to make the trek. The entire East Wall is not groomed and should not be taken lightly since evacuation by the ski patrol in this area is a difficult undertaking.
