Aspen airport (ASE) is minutes to any of the four mountains in the area. You can hire a rental car, arrange a shuttle with your hotel, or take tne of the free city buses with all of your ski gear.
Alternatively, Denver International Airport is a four-hour drive and rental cars are available. Keep in mind, weather is unpredictable in the winter and the Vail Pass can be closed during snow storms. Check the weather and plan for mountain driving.
Once you and your guide agree on the details of your itinerary, your guide will suggest the best place to meet, usually at the guide shop in Aspen Highlands Village. From there, you’ll head to the trailhead. The guide will choose the appropriate terrain dependent on conditions and the ski ability of the group.
We were steered toward Aspen Expeditions through a friend who had taken Avy classes with the principal owner Amos. When it came time to plan a trip to Japan, the choice was a no brainer- Amos is a pinned IAMFG / AMGA guide, one of the first in the states. Unlike many Japan ski trips, Aspen Expeditions avoids the crowded spots in favor of SNOW. The trip consisted of equal parts back country, lift-assisted back country, and side-country. Each day ended with an Onsen (hot springs) and a meal fit for a king. On top of that, Amos had the foresight to hire a Japanese guide- clutch move to unlock next-level secret stashes of both food and snow. I would tell you to go, but I may be filling these spots every year that they are offered…
