Campers at Porcupine Mountains Wilderness State Park [1] have their choice of two campgrounds ($14–25), both with a number of sites overlooking Lake Superior: Union Bay (with full hookups and modern restrooms) at the east end of the park or rustic Presque Isle (no hookups) near the mouth of the Presque Isle River on the park’s western edge. In addition, three rustic campgrounds (called “outposts”) with 3–8 sites each are located off the South Boundary Road, accessible by car, but with no facilities. They tend to offer more privacy than the actual campgrounds.
As another option, the park offers 19 hike-in rustic cabins ($60). These are great retreats after a day on the trail. They come with 2–8 bunks, mattresses, a woodstove, basic utensils, and protection from the elements, but no electricity or running water. Bring your own stove for cooking. Cabins situated on inland lakes even come with a rowboat, so you can finish the day with a lazy drift across the water. Three yurts ($60) and a lodge are also available. Reserve any of these as much as a year in advance (800/447-2757).
