2. Harding Icefield Trail, Kenai Fjords National Park
8 miles, round-trip
Step back into the ice age with this spectacular day hike located near Seward in Kenai Fjords National Park. The four-mile trail climbs steeply from the valley floor, through forest and meadow, before rising above tree line and ending at a jaw-dropping lookout over the Harding Icefield—an enormous sheet of snow and ice that stretches for over 300 square miles and spawns 40 glaciers in all directions. There are many scenic vistas en route with stellar views of Exit Glacier and the Resurrection River.
