To celebrate the National Park Service's 100th anniversary this August, USA TODAY will be highlighting one national park per week in a countdown to the centennial on August 25th. From the awesome beauty of Rocky Mountain National Park and Grand Teton National Park, we turn now to a wilderness so inaccessible that you can only get to the park via seaplane or boat. Only 209 miles of the nearly 900 square miles in Isle Royale National Park are above water, but what land is there is teeming with wildlife and spectacular views. Take a virtual trip through Isle Royale National Park with videos, photo galleries, and more all week.
