02 of 10 Exit Glacier, Near Seward, Alaska Photo Courtesy of Austin-Lehman Adventures Located in Kenai Fjords National Park, Exit Glacier is another hike that Kasey easy shouldn't be missed. You'll find yourself traversing several mountain ecosystems beginning at the trailhead and making your way through shaded, towering cottonwood trees before making your way through meadow and forest on the way up to alpine tundra. After that, you are “walking on the moon” over a stark, otherworldly landscape of rock and ice. This “strenuous” trail takes 6-8 hours to hike, and you’ll gain about 1,000 feet of elevation for every mile. As you ascend the trail, take in views of Exit Glacier and the extensive Resurrection River stretching into the valley below. Upon reaching the summit –– on a clear day at least –– you can see for miles across the Harding Icefield.
