Climb Denali with Alpine Ascents

Everything I hoped for. Both of these guys are top notch guides. These guys consistently used every opportunity to teach us how to be better climbers. I was impressed how they would tutor us, but not treat us like children. They expected us to be experienced climbers and demanded that we rise to the occasion. It was great. As always with Alpine, everything was 1st rate. Particularly the Hilleberg tents. Great addition – especially as a cook tent. They made it easy for us to get together as a group. I normally have suggestions, but this trip was blessed with great guides and a strong climb team. I wouldn’t have changed anything.

Once again, AAI provided a top quality, first class expedition with great attention to all details. – 2016 Climber

There are certain mountains that need no explanation as to why climb. Denali is such a mountain. Its tremendous size and beauty generate a magnetism that continually draws climbers from around the world. An ascent of Denali touches the psyche of all alpinists, and for those who have undertaken its challenges, it rewards them with an unforgettable, once-in-a-lifetime experience.

Alpine Ascents has been running successful Denali expeditions for nearly 20 years. 2016 was a banner year in terms of overall climber success seeing an 86% summit success rate. We attribute this to the quality of our guide staff, logistics and climber training and screening. In 2015 we also saw outstanding success with 9 of 11 teams reaching the summit. We look to have similar success in 2017 and as always, we are happy to put you in touch with former climbers. We are committed to keeping up our high standards of food and logistics and look forward to the 2017 Season.

Alpine Ascents offers small group sizes of either 9 climbers and 3 guides or 6 climbers and 2 guides. We can also arrange private trips for smaller group sizes. Please note it is imperative for any size group that all climbers are in excellent physical condition and well trained in the necessary climbing skills to ascend Denali. Please see our Denali Screening page.

Alpine Ascents has climbing concessions on both Denali and Mount Rainier and offer training courses in both locations. These mountaineering courses are an excellent way to make sure your climbing skills and physical conditioning meet the requirements to attempt Denali. Alpine Ascents has very high prerequisites for our Denali climbers because we know your climb will be more enjoyable, safer, and have a greater chance of success if all members are well-prepared for the rigors of Denali.

Please contact us with any questions. Our Denali climbs fill early every season.


Denali requires proficiency in basic mountaineering skills including: expedition camping skills, cramponing, walking on snow, self arrest, crevasse rescue, and glacier travel on a rope team. Gaining these skills generally requires, at minimum, of completion of our Denali Prep Course (this course is best for climbers with some prior experience as early season conditions can prove difficult for learning basic skills), or our 6-Day Training course, 8-Day, 9-Day, 10-Day, 12-Day, 13-Day or have equivalent skills and experience. It is our goal to have similarly skilled climbers on our expeditions and we have thorough Denali screening guidelines. Read More

While a select few climbers were able to successfully join a Denali trip after a single course, the vast majority will greatly benefit from more climbing experience. We look to work with and assess each climber on an individual basis. Please contact Gordon Janow at to discuss preparing for Denali or to share your climbing bio.

About The Mountain

Denali is often considered North America’s most classic climb. From base to summit, it rises nearly 18,000′, an elevation gain unsurpassed anywhere in the world. At a northern latitude of 63°, it is the most northerly of any big mountain over 20,000′. No other region offers such breathtaking and diverse views each day of the ascent. The panorama from Denali’s summit includes Mt. Foraker, Mt. Hunter and Mt. Huntington in all their majestic glory.

When Dr. Bradford Washburn pioneered the West Buttress route, he heralded in a new era of Denali ascents and offered climbers a unique approach to the summit. The flight onto the glacier is a trip in itself, presenting overwhelming vistas of the Alaska Range. The West Buttress route remains, by far, the most successfully climbed route on the mountain.


A Brief History of Denali

Highest Mountain in North America. Denali has always been revered by native Athabascans who inhabit this northern region. The first climbing attempt was made by the Sourdough Expedition (William Taylor and Pete Anderson) utilizing the Muldrow Glacier. They summitted the north peak (19,740’) in 1910. About three years later, in 1913, the true summit was reached. A team comprised of Archdeacon Hudson Stuck, Robert Tatum, Walter Harper and Harry Karstens successfully climbed the south peak. It was Harper, a native Athabascan, who first stood atop North America. Between 1913 and 1950, there were very few ascents of Denali. The landmark achievement, which opened Denali to a larger group of climbers, was Bradford Washburn’s 1951 expedition, which reached the summit of Denali via the West Buttress. Washburn’s team, using a plane fitted with skis to access the Kahiltna Glacier, pioneered the most popular route on the mountain.


As Everest is to the Tibetans, Denali is inseparable from indigenous Alaskan lore. Every native Athabascan who saw Denali towering over their horizon named it accordingly, “The Great One” or “The High One.”

Denali (The High One) is the native Athabascan word for North America’s highest peak. It was renamed Mt. McKinley for William McKinley, a one-time presidential nominee, by gold prospector, William Dickey. Common usage has reclaimed the native name, Denali.

The Climb

A Denali climb begins deep in the heart of the Alaska Mountain Range on the Kahiltna Glacier. From the S.E. Fork of the Kahiltna Glacier we begin the climb of Denali’s West Buttress. Base Camp plus five higher camps are established on the mountain. When necessary, the team makes double carries between all camps, except high camp, to ensure proper acclimatization and reduce loads. In each camp we build snow walls for protection from possible high winds. The climb takes approximately 17-18 days round trip from Base and we add an additional four days to allow for inclement weather, acclimatization and optimal summit attempts. The ascent requires intermediate mountaineering skills and is physically and mentally demanding.

Climbing Conditions

Denali is a mountain of extreme conditions where a climber may encounter 100-mph winds and – 40°F temperatures. Alternately, some days are quite hot with sunshine lasting up to 20 hours. These low temperatures and sporadic high winds greatly increase the rigors of the climb. Snowstorms are known to last a week at a time. The unpredictable weather coupled with the high altitude requires not only technical snow and cold weather skills, but also endurance and fortitude.

What is the skill level of this climb?

Climbers should have successfully completed our Denali Prep Course, 6-Day Training course 13-Day Training course 8-Day Training course 10-Day Training course Alaska 8 Day Course, Alaska 12-Day Training course or have equivalent skills and experience. This climb requires proficiency in glacier travel, crevasse rescue, cramponing, and expedition camping skills. It is our goal to have similarly skilled climbers on our expeditions. For more information, please see our Denali screening guidelines.

What is the physical conditioning level needed for this climb?

Excellent physical conditioning is needed. Packs can weigh over 45 pounds in addition to a 20 pound sled. Travel is sometimes through deep snow in harsh weather conditions.

Any tips on how a climber can maximize their chances of success?

Along with the required crampon skills, review cardio training on the training page of our web site. Our itinerary provides a fair amount of time to acclimatize before attempting the summit. We strongly recommend following the advice of our guides to acclimatize properly. Please click here for the Denali Training Regimen and accompanying article, “So You Want to Climb McKinley?” by Stacy Taniguchi.

Who is the guiding team composed of (How many guides? Climber to guide ratio?)

We utilize a 9:3 climber to guide ratio for added logistical support on the mountain. The most unique aspect of our climb is the 3:1 climber to guide ratio. Small group sizes not only improve your chance for summiting but also provides a much richer experience.

What is the best season to climb / which dates will have the most chance for success?

May, June and July are the best months to climb Denali. Harsh weather and storms are not uncommon on Denali, though the frequency and duration vary from year to year, making it difficult to predict which trips will encounter such conditions.

How many climbers are on this expedition?

Our client to guide ratio for this climb is 9 climbers plus 3 guides for all departures.

Will I be sharing a tent or lodging with other climbers?

Yes, you will share a tent. At the lower camps 2 people share a 3 person tent. At high camp, teams often go with 3 people to a tent to save weight.

How much will my pack weigh?

Your pack will weigh up to 40 to 60lb with a 30 to 50lb sled (total weigh combined 65 to 70 lbs) for up to 6 hours per day. Higher on the mountain where we don’t use sleds, your pack weight can be as high as 65lbs

What gear will I need?

Please review the gear list.

How does your gear rental system work?

Those requesting rental gear must submit an expedition rental form with payment by fax or mail. All rental gear will be mailed to the climber prior to the climb. Climbers are expected to clean all rental gear and return it to us by mail following the expedition.

Any further advice on gear and using your gear list?

While all items are required there may be times when some of the items on the gear list may not be used (such as warm weather or changing conditions). The gear lists are created by our guides to assist in having climbers be prepared to summit in any conditions. When purchasing gear for Denali and other expeditions, we encourage you to contact us to discuss the best options for purchasing with future needs in mind.

While it is impossible for us to list all brands for certain gear, we do offer a wide variety of equipment in our Gear Shop, that has been hand-picked by our staff of mountaineering experts. Please feel free to call our offices with any gear questions or substitutes. Plastic boots are required for this climb.

How is drinking water treated?

All water will be melted snow while the group is on the mountain. Melting will kill anything that can live at the altitude the camps are located.

What will the meals on the expedition be like?

Meals in the mountains consist of a diet rich in carbohydrates because our bodies do not process fat and protein efficiently at higher elevations and to compensate the increase in caloric need that high altitude climbing involves. We try to make meals and breakfast varied and as normal as possible.

Can I bring some food from home?

You may bring power bars, Gu, Power Gel, cereal bars or similar high energy foods, powder Gatorade is also recommended to fight dehydration. All meals will be provided on this expedition.

Are there any innoculation requirements?
