Waterton Lakes National Park
Together with neighboring Glacier National Park in the United States, Waterton Lakes National Park is part of the world's first international Peace Park, which was recognized as a UNESCO World Heritage Site in 1955. The Waterton-Glacier Peace Park protects an important biological crossroads where the Rocky Mountains reach their narrowest width. Waterton's bedrock is much older than that of the mountains to the north found in Jasper and Banff.
