Waterton-Glacier International Peace Park[dead link] is a UNESCO World Heritage Site located directly on the 49th parallel, the boundary between Alberta, Canada and Montana, United States of America.
It consists of two contiguous national parks in two countries:
| Waterton Lakes National Park in Alberta. |
| Glacier National Park in Montana |
Both parks were declared Biosphere Reserves by UNESCO in 1976 and as World Heritage Sites in 1995.
Although physically it is possible to cross the USA-Canada border at a number of points by foot or boat, park warden checkpoints target hikers at a number of geographical funnel points. Canadian and US citizens should have their passport with them, other nationalities cannot simply hike across and must use one of the main official border crossings (for computer based checks). The most convenient crossing is 1 Chief Mountain Port of Entry on the Waterton - Babb road. This is not open 24 hours.
