Four hours by car to Bayfield, another hour or so on a ferry boat, and you're suddenly on a secluded island in the middle of Lake Superior. Perhaps you've secured a campsite safely near the dock, with water and a tent pad readily available. Maybe you've selected one farther out, near the old-growth forests or sandy beaches. Or maybe you've gotten a permit for minimal-impact wilderness camping, in which one group of campers per night is allowed within a large designated zone spanning 15 of the 21 Apostle Islands. In any case, the boat won't be back until morning, and miles of trails and lakeshore await you. Cost for individual camping parties of up to seven people is just $15 for up to 14 nights, and $30 for groups of eight or more. The Apostle Island Cruise Service, run by the National Park Service, will get you to three islands (Oak, Stockton, and Manitou) for just $24.95 per adult, $13.95 for children. Private boats and cruise services for the other islands can cost more (upward of $70 apiece) and are easily found on the Internet, or by calling the above number.
