Denali is the native American name for the mountain but it was changed to Mt. McKinley in honor of President McKinley and the surrounding park was named Denali National Park by the National Park Service in 1980.

In 2015, the name of the mountain was officially changed to Denali. It is in central Alaska - 300 miles South of the Arctic Circle and 200 miles East of the Bearing Sea.

Denali offers some the the largest vertical gain of any mountain on Earth. With base camp at 7,200' and the summit at 20,310', this 13,110' of gain over twelve miles is larger than Cho Oyu (8,407) or even Everest (10,535).

The biggest threat on Denali is the weather. It is well known for socking you in for days with high winds and snow..


The West Buttress, West Rib, Cassin Ridge, and Muldrow are the most frequently climbed routes on Denali. The West Buttress and the Muldrow are the least technical ascent routes; the primary climbing difficulties are crevasses, steep ice and exposed ice-covered ridges and, of course, the environment.

In recent decades, over 90% of climbers on Denali attempt the West Buttress. With this many climbers in a short season, climbers can expect to encounter several hundred others during the last week of May and first week of June.

The Walter Harper Talkeetna Ranger Station has reference materials for various routes on Denali and other peaks in the park, and ranger staff are available year-round to help with route selection. Several excellent guide books are available for the high peaks of the Alaska Range.

Safety Notes Specific to the West Buttress Route by Denali NP

NPS rangers and mountain guides operating on Denali work together to maintain fixed lines on the headwall above the 14,200-foot camp. All teams should be familiar with the equipment and techniques needed to safely ascend and descend these fixed lines. Additionally, teams should always be prepared to place their own snow and ice anchors in the event the fixed lines are damaged, buried, or missing entirely.

The NPS rangers and mountain guides also install and maintain fixed snow pickets on the traverse between the 17,200-foot high camp and Denali Pass at 18,200 feet. This area has been the scene of many climbing injuries and fatalities, largely as a result of unprotected falls. To help lessen the fall potential for teams traveling on this slope, fixed pickets are placed approximately every 27 meters and include a sling and fixed carabiner to be used as "running protection". Rope teams must be familiar with appropriate team member spacing and how to pass fixed protection to make use of this safety measure. Teams should also be equipped to place their own snow pickets in the event of missing or buried fixed protection.

Moving quickly and efficiently on these protected sections of the West Buttress route is important to reduce congestion, as well as to keep your climbing team and other nearby teams safe.


An estimated 32,000 climbers have attempted Denali with about a normal 40% success rate.

Belgian Denali expedition

After Stef Maginelle climbed Mt Denali in 2004 as preparation for his Everest Expedition , Sofie went in 2012 towards Denali also as preparation for here first 8000+ expedition.

We both climbed by the West Butress route. Our climbs were non guided and self supported.

We flew from Frankfurt directly to Anchorage. The flight went with the sun 10 hours backward and over the magical North Pole. Stunning images of kilometers of ice and snow, unreal

21 may they took a small aircraft over the wild nature and into the mountains to the base camp at 2194 m on the Kahiltna Glacier. In the distance we saw a glimpse of the McKinley aka Denali which means "the tall or big." Because it is located just below the Arctic circle, where the atmospheric conditions reduce the oxygen pressure, the ascent of this mountain corresponds to the climbing a 7000er in the Himalayas.

From this base camp at 2200m, leaving the grueling trek with sleds from 20 to 30kg and 25kg packs of 20 to the enormous Kahiltna glacier; the views are breathtaking.

camp 1 located approximately 2400 m

2nd camp at about 3000m,

23 may towards Basin Camp at 3400m

From basin camp you have the choice of two systems to continue; single or double carry. In a double carryover  you bring the first load up that you dig, in a cache. You descend again and the next day you wear the rest of your stuff up. We have done everything in one single push = carry everything at once.

The expedition went super well, summiting 27 may 2012 after only 6 days of climbing and one rest day

The four deceased climbers were buried under heavily compacted ice and snow debris, and were unable to be recovered safely.

Denali Expedition Basics by Alan Arnette

Q: Which route is most popular?

A: The West Buttress is the most popular. The other routes including Cassin Ridge, West Rib & South Buttress are extremely technical and subject to avalanches. 98% of all Denali climbers use the West Buttress route.

Q: How long will it take?

A: 2 weeks on the mountain plus another few days to get onto and out of the mountain so allow at least 3 weeks. However, it is very common to be stuck for another week somewhere on Denali with bad weather.

Q: How much does a standard climb cost with and without a guide?

A: The costs can range from $6500 to $8000 depending on who you use. Comment: I cannot understand these prices on Denali and feel there is a significant lack of competition that has lead to this situation. If you do everything yourself cut the highest cost in half or more and should cost no more than $2000 assuming you have the basic gear. See my Guide page for more details.

Q: Do I need a permit to climb?

A: Yes. All climbers must register and pay a $350 fee as of the 2012 season to the National Park Service at the park headquarters in Talkeetna. This can be done online. There is a limit of 1500 climbers, guided or unguided, each season which has never been exceeded.

Q: Are there local guides for Denali?

A: The NPS has approved 6 companies to guide e.g. (charge a fee) on Denali: Alaska Mountaineering School, Alpine Ascents International, American Alpine Institute, Mountain Trip International, N.O.L.S. and Rainier Mountaineering Inc. The NPS requires a 3:1 climber to guide ratio. Anyone caught 'guiding' are removed and fined according to Rangers. Due these regulations almost all the companies charge the same price, run the exact same program and have the same conservative attitude. There have been several deaths over the past few years on commercial trips as well as private ones.

Q: Do I really need a guide for Denali?

A: It all depends on your skills and experience. The monopoly on Denali has created a suspect environment for most commercial outfits causing them to be very conservative. Most commercial Guides are good people but given they run multiple climbs each year (as many as 3 or 4 climbs per guide), they act burned out and appear to have little motivation to go to the summit, especially late in the season. Another issue with the companies who have a NPS concession is that they squeeze as many trip as possible (around 11 back to back) into the three month climbing season. As a result there is virtually no time for weather delays. So once your time runs out, regardless of the weather, it is time to go and your climb is over. With the crazy weather patterns in recent years on high mountains this is becoming a huge issue resulting in many climbers missing summits due to schedules and financial considerations by the operators.

If you want a guided trip I suggest selecting a company who runs only one or two climbs each season through getting a permit from one of the authorized guides. The guides will more fresher and maybe more motivated. However, make sure they use their own guides and do not simply subcontract back to the permit owner which takes you back to the original issue.

If you can go without a commercial guide, you would probably have a more positive experience. But you need to have the skills and qualified partners. Denali is dangerous and you can die. There are usually a lot of climbers on Denali so you would probably not be alone but easily could be. In harsh weather (white-outs) or in a medical emergency, you will be on your own so consider your skill level carefully. Also crevasse danger is real and always present on the lower glacier area so crevasse rescue skills must be second nature to everyone on the team. Climbing alone or in too small of a team is never a good idea.

Q: How do you get on an expedition to climb Denali?

A: Most reputable guides ask for your climbing resume and require some climbing experience. Ideally they want to see climbs of Rainier or Colorado or California 14ers. But most anyone can get on a Denali commercial expedition these days without many questions and that is a real problem. The guide services all run the same basic formula on the West Butt route and are very conservative with weather, safety and risks.

Q: What is involved if I plan my own climb?

A: Basically everything: permits, travel, hotels, food, gear, routes, communications, emergency contentions - everything. You can save a lot of money this way, well over half the list price, but as I said before, consider your skills in the event that something goes wrong - are you self sufficient? What are your medical skills? HAPE and HACE are really possibilities on Denali - do you have the proper medicine and training to deal with it? And a hundred more questions. The Rangers will strongly discourage solo climbs. You must bring a two-way radio and a sat phone in my opinion and have the frequency or number of the local rescue resources already programmed in. For help with meals and logistics, An excellent resource is from Tim Hult after his 2005 climb. He created a somewhat exhaustive guide to climbing Denali on your own. for commercial trips, see my guide page for more information.

Information given by Denali National Parc

Solo Travel

The National Park Service strongly recommends against solo travel.

Even the most cautious and experienced climber is unable to determine the location or strength of the many snow bridges that must be crossed. A solo climber has virtually no self-rescue ability in the event of a crevasse fall, illness, or a serious accident, and thus creates an undue risk to a search and rescue party.

Solo travelers are required to submit a lengthy supplemental solo registration form upon registration that asks for details on equipment carried, plans for self-evacuation, and other emergency information.


Guided Expeditions

A Denali expedition can provide a tremendous mountaineering challenge, but it is not without risks. For many climbers joining a guided expedition can provide for a safer and more functional trip than they could construct on their own. Over the past several decades, an increasing number of climbers seek the benefits of a guided expedition, including:

•Expert advice on equipment and training

•Less logistical planning and effort

•Experienced team leaders with a primary responsibility of safety

•Ability to join a group of climbers with similar goals and experience

•A guide's knowledge and experience can provide many people with the best possible chance of having a successful experience on Denali

Only the six guide services listed below have been authorized by Denali National Park to lead commercial expeditions on Denali. Unauthorized guiding is an illegal activity. Law enforcement rangers will prosecute illegal guides and illegally guided team members which can include both fines and time in jail.
