The Park Service shuttles visitors to various island attractions on its 25-passenger MV Sandy. (906/482-0984, www.nps.gov/isro, June–early Sept., fare rates vary). The Sandy makes several different trips in season. One four-mile boat ride takes passengers to the Hidden Lake Trailhead, where they are asked to debark and guided on a two-mile round-trip hike past Hidden Lake, up 320 feet, to Lookout Louise. From here, visitors can view the southern shore of Canada and the northern shore of Isle Royale.

Another trip heads across the mouth of Moskey Basin to the historic fishery of Peter and Laura Edisen, restored to show what life was like for the commercial fisheries that once thrived on the island. From Edisen Fishery, it’s a short quarter-mile walk to the stout and simple Rock Harbor Lighthouse, a white edifice built in 1855 to guide ships to Isle Royale’s then-busy copper ports.

Other tours feature out-of-the-way destinations such as Middle Island Passage and Starvation Point. History buffs, too, will enjoy these tours. Besides viewing the Rock Harbor Lighthouse, you can also select a tour to see the Passage Island Lighthouse, the historic Minong Mine, and the site of the Monarch shipwreck.
