Glacier National Park in Montana spans over 1,000,000 acres and is one of North America’s epic backpacking destinations. It borders the Canadian provinces of Alberta and British Columbia and includes parts of two mountain ranges that help to make up the Rocky Mountain range. Glacier National Park borders the Waterton Lakes National Park in Alberta, Canada, and together the two parks make up to Waterton-Glacier International Peace Park.
The park encompasses numerous ecosystems, from prairie to alpine tundra, as well as the easternmost examples of red cedar and hemlock forests.
The park is home to several hundred animal species, including moose, bighorn sheep, mountain goats and coyotes. Two threatened species, the grizzly bear and the Canadian Lynx, live in the park. A 2008 study estimated that there are approximately 300 grizzly bears in the park.
Two national scenic trails traverse Glacier National Park. The Continental Divide Trail crosses the park from north to south for 110 miles, and the Pacific Northwest Trail crosses east to west for 52 miles. In total, the park has over 700 miles of trail, much of which is inaccessible except during summer months due to heavy snowpack and avalanche danger.
