As one of the most visited national parks in Alaska, Kenai Fjords is best known for their glaciers and incredible wildlife viewing opportunities. Personally, I think the best way to experience the fjords are through a glacier & wildlife tour out of Seward (we always recommend Major Marine Tours) however if you head in the back way towards Exit Glacier there's also multiple hikes to do in the area - like to the Exit Glacier overlook (easy) and to Harding Icefield (difficult). Watch our tour with Major Marine here or check out the hike to Harding Glacier here.
