One of the largest ice fields in the United States (Harding Icefield) is in southern Alaska’s Kenai Fjords National Park. It contains 38 glaciers but only one is accessible by car (Exit Glacier). To explore the rest of the park you’ll need to hike, boat, or fly.

The icefield was generally unappreciated until 1922. That’s when Spruce Creek trail was constructed. It offered a glimpse of the icecaps’ upper portions, garnered the attention of then President Warren G. Harding, and the rest is history.

In addition to Exit Glacier, consider hiking the 8.2 mile Harding Icefield Trail, jumping on a boat tour to get close and personal, skipping the crowds by kayaking through the Kenai Fjords for yourself, or taking the most expansive approach by viewing Kenai Fjords National Park by flightseeing.
