Grand Portage State Park is a state park at the northeastern tip of Minnesota, USA, on the Canada – United States border. It contains a 120 feet (37 m) waterfall, the tallest in the state, on the Pigeon River. The High Falls and other waterfalls and rapids upstream necessitated a historically important portage on a fur trade route between the Great Lakes and inland Canada. This 8.5-mile (13.7 km) path plus the site of forts on either end are preserved in nearby Grand Portage National Monument.
