Outer Island Lighthouse is located on the furthest of the Apostle Islands, Outer Island , in Wisconsin’s Ashland County. The lighthouse is on the northern tip of the Island. It was established in 1874 to help guide ships to and from the port towns of Duluth and Superior. The 90 feet (27.4m) tall light tower is attached to a two story brick light keepers dwelling. Visiting Outer Island can be difficult. Only the most experienced boaters should attempt a trip to this lighthouse because of the distance and exposure to tumultuous Lake Superior.
Boat tours departing from Bayfield to the island are offered where you can explore the grounds. During the summer season, there are volunteer rangers on most of the islands to receive visitors for tours. There is an annual Apostle Island Lighthouse Celebration that presents opportunities to view the lighthouses on a cruise boat.
