Denali

Climb Denali with Alpine Ascents

Great trip, excellent guides, will definitely recommend to anyone who is interested in a Denali trip. The fact that all of our trip made it to the summit and all of the second trip of the season made it !… is a testament to the quality of the organization, team, guides, and process that is used to ensure a safe and successful trip.

Unreal. Breathtaking. All the details of the expedition were thought through and there was never a moment where I doubted the leadership. And the food was delicious.

Our Denali expedition was meticulously planned and flawlessly executed. Our guides were knowledgeable, engaging, friendly, fun, and incredibly supportive. This was my fourth attempt at Denali and my 16th AAI trip in the last twenty years. I’ve come to expect high levels of service and professionalism from the company, and my expectations are always exceeded!

I thoroughly enjoyed every bit of the expedition; from the independence, the physically demanding nature of the mountain and the environment, the camaraderie from the team and, of course, the exhilaration of achieving the summit!

Excellent short film by Alpine Ascents climber Andrew McCarthy from our June 2018 expedition:

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 25+ years and is extremely well regarded  among concessionaires. Our 2022 season was outstanding with an 83% team success rate and the two teams that did not summit aborted their summit attempt to assist with a rescue ( we may have had 100%! ) In 2021 we had an outstanding season  season with a 73% climber success rate amongst amidst a challenging weather season.  2019 proved to be one of our best seasons with all teams but one reaching the summit; and perhaps our highest climber summit success to date. Alpine Ascents is traditionally known to have some of the highest success rates on the mountain. We look forward to having similar accomplishments in 2023 and — as always — we are happy to put you in touch with former climbers. We are committed to keeping up our high standards for food and logistics, and we look forward to the 2023 season.

Our Denali climb was recommended by Lonely Planet, 2017.

Alpine Ascents offers small group sizes of nine climbers and three guides. We can also arrange private trips for smaller group sizes. Please note: it is imperative for groups of any size that all climbers be 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 Mt. Rainier, and we offer training courses in both locations. These mountaineering courses are an excellent way to make sure your climbing skills and physical conditioning meet the necessary 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.

I was very impressed by the whole experience. It lived up to all of my expectations. It has been my dream to climb Denali for quite a while now and AAI and the awesome guides made it possible. I can’t say enough good things about the guide team I had.

About The Mountain

Denali is often considered North America’s most classic climb. From base to summit, it rises nearly 18,000ft., an elevation gain unsurpassed anywhere in the world. At a northern latitude of 63 degrees, it is the most northerly of any big mountain over 20,000ft. 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

The 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 summited the north peak (19,740’) in 1910. About three years later, in 1913, a team comprised of Archdeacon Hudson Stuck, Robert Tatum, Walter Harper, and Harry Karstens successfully climbed the south peak, reaching the true summit. 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.

Lore

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” 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 Range on the Kahiltna Glacier. From the Southeast 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 minus 40 degree 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.
