Denali National Park features North America’s tallest peak: the massive, 20,000+ foot mountain that gives the park its name. Once known as Mount McKinley, Denali ranks among the world’s seven summits as the tallest mountain on the continent. Expeditions can last as long as 20 days with success rates hovering around 50%. But you don’t need to be a master alpinist to explore this Alaskan park. The best hikes in Denali National Park give you grand views of the central summit, and of the meadows, glaciers and creeks that encircle it. Hike the Kesugi Ridge trail if you want a challenge or stick with Mount Wright if you can only spare a day.
