The size of six Yellowstones, Wrangell-St. Elias National Park is the largest National Park in the United States. Named for the two mountain ranges on which it sits, and containing nine of the sixteen highest peaks in the US, Wrangell-St. Elias is a place of extremes. A visit to the park is not for the faint of heart; there are glacial rivers to fjord, rocky slopes to climb and bears to avoid, all without the help of a trail. The unparalleled beauty, however, makes any trip worth the effort.
