At 20,320 feet Denali, sometimes called Mount McKinley, is North America’s highest mountain. An expedition up Denali is a multi-faceted commitment. It can take up to three weeks on the mountain to make the summit. This is due to the high altitude and time it takes to safely acclimatize to the thin air and the nasty weather that can pin climbers in camp for days at a time. Climbing Denali is not for the inexperienced climber so months to years of training and experience are needed to make the top. Denali is also part of the Seven Summits: The highest mountain on each continent and within this group some say it is even harder to climb than the world’s highest mountain, Mount Everest.
