On the northeast side of Isle Royale National Park, the Passage Island Lighthouse guides ship traffic between the channel of Isle Royale's main island and Passage Island. Completed in 1882, the lighthouse originally used a Fourth Order oil-burning wick lamp and appeared as a fixed red light; later, it was modified to a flashing white light. Concession tours regularly travel to the island, giving visitors a glimpse of this now automated and unmanned sentinel of the past that continues to provide safe passage to ships today.
