If you spend tonight in Houghton, Copper Harbor, or Grand Portage, which National Park are you likely visiting tomorrow?

Isle Royale, above the Upper Peninsula of Michigan, has the distinction of being accessible only by boat or seaplane. The closest departure point is Grand Portage, Minnesota, which is just over 2 hours away by boat. Because of its remote location, it's also the only National Park in the country to close completely during the off-season.
