Glacier National Park borders Waterton Lakes National Park in Canada — the two parks are known as the Waterton-Glacier International Peace Park, and were designated as the world's first International Peace Park in 1932.Both parks were designated by the United Nations as Biosphere Reserves in 1976, and in 1995 as World Heritage sites.The park is also one of the largest remaining natural grizzly habitats, and during late summer, grizzlies will often come to lower elevations to eat the area's popular berries and catch fish in the lakes.In addition to grizzly bears, the park is also home to two other endangered species: the Canadian lynx and the bull trout.During the park's summer season, temperatures during the day can reach as high the 90s Fahrenheit (over 30 degrees Celsius), but nighttime lows in the highest elevations can occasionally be around 20 degrees Fahrenheit (less than -5 degrees Celsius).
The western side of the park tends to receive the most rainfall, whereas the eastern side tends to have higher winds and more sun.
Travelers should arrange accommodations and/or waiting time accordingly.
In addition, trains will stop at the Izaak Walton Inn at Essex Station, by request.
Amtrak's Empire Builder train service runs from Seattle and Portland through northern Montana, North Dakota, Minnesota, and Wisconsin to Chicago.
The Empire Builder westbound train arrives in the evening while the eastbound train arrives in the morning daily at the three stations serving the park.
