The ten climbs listed to the left sample the best the Park has to offer and use all the techniques of modern mountaineering---some climb snow, some ice, some rock, and some all of the above. This is a tiny portion of the climbing available - only the Tetons in terms of the quality of alpine climbing rival Rocky Mountain National Park.
Climb descriptions on the linked pages list some of RMNP's more exceptional climbs, and include some of the qualities that make each climb unique in Colorado climbing.
Both Bernard Gillet's Rocky Mountain National Park:The Climber's Guide and Richard Rossiter's Rock Climbing Rocky Mountain National Park: The Crag Areas and Classic Rock Climbs No. 08 The Diamond of Longs Peak, Rocky Mountain National Park will include the details you need once you decide on a climb.
I've tried to include mostly moderate climbs. By the time you are ready to climb The Joker (5.12c) on the Diamond or Vanquished (M6, AI 5) on Powell, you probably do not need this list. If you have any questions about the routes or the present conditions, please feel free to call or drop in at the Colorado Mountain School 970-586-5758. We are the only service legally authorized to guide in Rocky Mountain National Park; we'd love to take you up any of these climbs.
