Savanna Portage State Park, Minnesota

Named for the gnarly path connecting Lake Superior to the Mississippi River, Savanna Portage State Park’s main feature is a wooden boardwalk loaded with history. On the National Register of Historic Places, this path renders the mystical fog-laden marshland here passable, where for centuries travelers trudged through the bog to get between these two crucial points of interstate commerce. Nowadays, visitors can swim, boat, fish, or even ski at this all-season camping spot. They even provide GPS units for geocachers!

If hunting’s your thing, the Floodwood Game Refuge is inside the park, or you can venture out to nearby Hibbing, an old iron town where the mine tours are surprisingly cool. Off the beaten path on a bumpy road, you’re guaranteed seclusion from other campers at Savanna Portage (although we can’t guarantee privacy from bugs—those skeeters’ll getcha, come prepared!
