Adventure with Aspen Expeditions’ Expert Guides
Aspen Expeditions is a four season, technical mountain guide service based in the heart of the magnificent Rocky Mountains in Aspen, Colorado, where we have been guiding and teaching rock, ice, ski & alpine mountaineering skills since 1977. With our ski town heritage, we specialize in worldwide adventure skiing from the deep snows of Hokkaido, Japan, the fjords of Iceland and Norway, remote Alaskan glaciers, famed European hut traverses to the jagged peaks of the Andes and classic South American volcanoes.

“Fantastic lift assisted backcountry day with Nate. Very knowledgeable, timed the entire day to perfection and found some epic powder. Will definitely be back!”
— Timothy Fox
“I have done three climbs with AE, the Bells Traverse with Nate E, Capitol with Nate E, and Pyramid with Britt. I had a great time on all three trips and felt very safe the whole time. Would highly recommend!”
— Jeff Hughes
