Banff National Park (French: Parc national Banff) is Canada's oldest national park and was established in 1885. Located in the Rocky Mountains, 110–180 kilometers (68–112 mi) west of Calgary and 145 kilometers (90 mi) from Calgary International Airport in the province of Alberta, Banff encompasses 6,641 square kilometers (2,564 sq mi) of mountainous terrain, with many glaciers and ice fields, dense coniferous forest, and alpine landscapes. The Icefields Parkway extends from Lake Louise, connecting to Jasper National Park in the north. Provincial forests and Yoho National Park are neighbors to the west, while Kootenay National Park is located to the south and Kananaskis Country to the southeast.
Banff National Park has a subarctic climate with three ecoregions, including montane, subalpine, and alpine. The forests are dominated by Lodgepole pine at lower elevations and Engelmann spruce in higher ones below the treeline, above which is primarily rocks and ice. Mammal species such as the grizzly bear, cougar, wolverine, elk, bighorn sheep and moose are found, along with hundreds of bird species.
