The largest national park in the United States is Wrangell-St. Elias National Park at over 13 million acres. That’s 6X the next closest: Yellowstone.

It’s vast Alaskan wilderness includes 4 major mountain ranges, contains 9 of the 16 highest peaks in America, an active volcano, 3 of the largest glaciers in the United States, not to mention the many rivers, streams, lakes, and coastal waters.

Of particular interest is the abandoned copper mining town of Kennecott and its Million Dollar Bridge, where undoubtedly many millionaires were made in the early 1900s.

The park’s 20,000 square miles are only serviced by 2 gravel roads, so you’ll need to hike, bike, horseback ride, snowmobile, whitewater raft, kayak, mountaineer, ice climb, ski, snowshoe, and fly your way through its gigantic entirety.
