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. From a peak attendance of more than 600,000, Waterton Lakes National Park today receives about 350,000 visitors annually. There are boat rentals and stables, an 18-hole golf course, and a cruise to Goat Haunt Visitor Centre in Montana. And for the traditionalists, there are over 250 kilometres of hiking trails that range from short strolls to multi-day backpacking adventures.
