To find the largest national park in America, head to southeast Alaska. Here you'll find a rugged park that's bigger than Switzerland.

Alaska's Wrangell-St. Elias National Park and Preserve covers 13.2 million acres. The park is named after the Wrangell and St. Elias mountain ranges that form the park's backbone. The Wrangell Mountains were themselves named after Baron Ferdinand Petrovich von Wrangel (1796-1870) and the St. Elias Mountains were named by Vitus Bering (1681-1741), Russian and Danish explorers, respectively.
