Adventure brief
McCargoe → Rock Harbor
Travelers seeking Lake Superior wilderness will find the McCargoe to Rock Harbor ferry an indispensable gateway. Enjoy spacious, scenic passages aboard the Voyageur II with stops at key trailheads around Isle Royale National Park.
Isle Royale National Park, located in the remote waters of Lake Superior, is a wild refuge known for its dense boreal forests, rugged shoreline, and crystal-clear lakes. This isolated island park, established in 1940 and designated a wilderness area, offers unparalleled opportunities for backcountry hiking, paddling, and wildlife viewing. Grand Portage Isle Royale Transportation Lines provides an essential gateway into this wilderness via the McCargoe to Rock Harbor ferry trip.
Aboard the Voyageur II, a stout 65-foot aluminum vessel specially designed for the Great Lakes environment, travelers cruise along Isle Royale's expansive perimeter. The ferry travels clockwise around the island, creating natural access points to scenic trailheads and paddling launch spots that otherwise require extensive trekking or kayaking to reach. Passengers can settle into comfortable indoor booth seating or take in fresh lake air from the bow and stern decks.
Amenities aboard include restroom facilities and private crew quarters, blending functionality with relaxation. This journey is more than just transportation—it’s a chance to witness Isle Royale’s diverse geology, from ancient volcanic rock formations to moss-draped forests and isolated beaches. Wildlife such as moose, gray wolves, and nesting loons add moments of quiet wonder to the voyage.
The overnight stay at Rock Harbor offers a peaceful landing spot with local dining and lodging, giving adventurers time to immerse themselves in the island’s solitude and natural beauty. Grand Portage Isle Royale Transportation Lines stands out as a vital service for accessing this remote national park. This operator not only connects adventurers to rugged journeys ahead but also supports the stewardship and preservation of Isle Royale’s fragile ecosystem.
