During the first hour of the trip, the ship navigates the scenic Keweenaw Waterway, passing under the world's largest lift bridge. Once on the open water of Lake Superior, riding the Ranger III allows one to appreciate the size and breadth of the world's largest fresh water lake (measured by surface area). As Isle Royale approaches, a picturesque seascape transitions to a rugged, lichen-covered shoreline and the historic Rock Harbor Lighthouse.
