Denali is home to some of the most severe weather and climbing conditions on the planet, so climbers looking to have a safe and successful climb on the mountain need to do an excellent job of preparing both mentally and physically for an expedition. The American Alpine Institute has nearly forty years of guiding experience on Denali and we have used our experience to tailor a program in the Cascades that will help prepare you for the challenges of climbing North America's highest peak. Please note that this is not a summit oriented course and no summit attempt will be made. 

Course Highlights

  • Learn Denali-specific skills on an expedition style course
  • Practice sled rigging, fixed line use and cold weather camping techniques
  • Review glacial travel, rope team travel and crevasse rescue techniques

Course Location and Conditions

This course is held on or near Mount Baker. Winter conditions can limit our access to certain areas and trailheads. A popular course location in heavy snow years is to access the backcountry area at Mount Baker Ski Resort. In March and April temperatures may dip as low as the single digits at night and the winds can be relentless. Heavy snowfall is not uncommon and you will more than likely encounter whiteout conditions for at least part, if not all, of this trip. In other words, the Cascades in the winter are the perfect training ground for Denali!

Because of the cold weather and harsh environment, climbers should plan on bringing all of the equipment required for a Denali Expedition, including their overboots and warm sleeping bags. Although these might not be required and/or used extensively on the program, making sure that all of your gear fits, works, and is up for the challenge is essential in preparing for Denali.

Denali Prep Course


This winter mountaineering and Denali preparation program is geared for folks with a basic to intermediate level of mountaineering skill and experience who are looking to prepare for and climb Denali in the near future. This program is set-up to be a mini-Denali expedition on which we will employ and use every skill and technique that climbers would expect to use on Denali. This will include the use of sleds, snowshoes, cook tents, and the use of fixed lines as well as a review of glacier travel, rope team, and crevasse rescue techniques.

Each course is led by at least one (depending on the number of climbers) of AAI's Denali guides, and participants will have the unique opportunity of getting direct feedback as to their level of preparedness and areas of training including physical conditioning and technical skill. Our hope is that by offering a prep program several months before the Denali expedition, we can help climbers round out the final pieces of their technical and physical training before heading to Alaska.

"I would recommend this course for anyone preparing for a Denali expedition. I also would HIGHLY recommend AAI and especially my guide. He was absolutely aware, skilled, well versed, chilled back just enough to be personable and smart (former Microsoft software engineer)!

For Denali hopefuls like me, whether or not one holds an extensive climbing resume, the prep course is invaluable. You learn how to deal with staying clean for 6 days, unforeseeable circumstances, expedition type lifestyle, getting along with strangers, and working together as a team. Not to mention skills that don't usually get used in general mountaineering like fixed lines, sled pulling, and rope team travel. I worry about team members that haven't had some type of course like this. The course also lets you and the guides know whether or not you are even ready for Denali. I'd hate to find that out in Alaska and lose a lot more time and money. All and all, amazing folks and an amazing mountain! I certainly cannot wait for Denali in June."
