Spring Couloir Climbs
  • Duration 1 Day
  • Technical Climbing

The Aspen area hosts some of Colorado’s best spring snow climbing routes to the summits of its many prominent “technical” 13’ers and 14’ers

From the classic 2,000’ “Y” Couloir up South Maroon to moderate snow climbs to the summit of Snowmass Mountain. Our spring peak snow-climbing season is typically in shape from mid April to early June. For our advanced snow climbs we will require prior snow climbing experience. For our moderate snow climbs we can work with clients with no snow climbing experience after a short day of self-arrest training and crampon techniques prior to the climb.

Some of our “must-do’s” include:

  • Snowmass Mountain (14,099’) east and west faces – moderate 2 day / 1 night trip
  • “Y” Couloir on South Maroon – advanced 40°-45° 2,000’ couloir
  • Bell Cord Couloir bisecting North and South Maroon Peaks (14,163’) – advanced 40°-45°, 2,000’ couloir
  • Conundrum Couloir on Conundrum Peak (14,064’) – moderate/advanced 40°-45°, 800’ couloir can be combined with a fairly quick tag of the summit of Castle Peak
  • North Face of Castle Peak (14,278’) – moderate 40°, 800’ couloir
  • Pearl Couloir on Cathedral Peak (13,950’) – advanced 40°-48°, 1,200’ couloir
  • Lightning Pyramid (13,722’) west face/couloir – advanced 45°-50° 1,000’ face
  • Grizzly Couloir on Grizzly Peak (13,996’) – moderate 35°-45° 1,200’ couloir
