Isle Royale reopens April 16

Isle Royale National Park reopens for visitors on Thursday, April 16, ending the island chain’s annual winter closure in Lake Superior. (nps.gov) The National Park Service closes Isle Royale and its surrounding islands to visitors from November 1 through April 15 each year, then reopens them on April 16. The park sits in northwestern Lake Superior and can be reached only by boat or seaplane. (nps.gov) Reopening does not mean every transportation option starts that day. The Park Service says the Ranger III ferry runs between Houghton and Rock Harbor, while Isle Royale Seaplanes typically operates from mid-May through mid-September, serving both Windigo and Rock Harbor. (nps.gov 1) (nps.gov 2) Visitors also have to budget for park entry on top of transportation. Isle Royale charges a $7 daily entrance fee per person for each calendar day in the park, including arrival and departure days, while children 15 and younger are exempt. (nps.gov) The park’s own season pass becomes the cheaper option once daily fees go above $60, or for people making more than one trip in a season. Ranger III fares are separate from that entrance fee, and the Park Service posts them on a different page. (nps.gov 1) (nps.gov 2) Early-season trips come with fewer services on the island. The Park Service says spring visitors in April, May, and early June should expect to be self-sufficient because services and emergency response can be limited to nonexistent. (nps.gov) That timing matters for anyone trying to book one of the park’s main public routes. Isle Royale Boats says its Voyageur II service from Grand Portage, Minnesota, starts May 9 for the 2026 season, and Isle Royale Line says its ferry from Copper Harbor, Michigan, takes about 3 hours and 45 minutes to reach Rock Harbor.
