The Canadian Pacific Railway snakes around the banks of the frozen Bow River on Dec. 7 as the sun sets on Morant's Curve, one of the most famous spots in Banff National Park in Alberta, Canada.

Established in 1885, Banff National Park is Canada's oldest national park. Featuring stunning ice fields, dense coniferous forests and glaciers, Banff is one of the most visited national parks in the world.
