Waterton Lakes National Park is located on the southern border of Alberta and is adjacent to Glacier National Park in Montana. Together, Glacier and Waterton form the Waterton-Glacier International Peace Park UNESCO World Heritage Site.
Waterton is much smaller than its neighbor to the south but may be more beautiful. Situated around Lake Waterton, the park has a gorgeous view of the surrounding Rocky Mountains. It also has one of the classic national park hotels in all of North America, the Prince of Wales Hotel.
Waterton should be a must visit for anyone who visits Glacier and vice versa. It is approximately a 2-hour drive from Calgary and it open year round, with summer being the peak season.
