What a beautiful park. I imagine how neat things must've been pre 9-11 when nobody cared about crossings on the northern border. Represents the trust the two sides had with a border like this. i can't think of any other countries who would have such an open border in this world, i'm sure there might be some friends like this though.
Visitors are allowed to explore both sides of the Canada-United States border inside the park, but are warned not to cross the boundary of the park to enter the adjacent country without being cleared to enter by the respective customs authority. Thank you for watching.
