This lighthouse near Juneau is located at Lynn Canal at the northern entrance to the Favorite Channel, between the mainland and Lincoln and Shelter Islands. Officially listed on the National Register of Historic Places, it takes a couple of hours to go visit this appealing site. Strong currents, rain, fog and rocky shorelines made navigating the Inside Passage very challenging. Alaska’s waterways acquired by United States in 1867 were marked by only occasional buoys and needed lighthouses for the vast coastline. George James, a Juneau resident built Sentinel Island Lighthouse in 1901. The original Sentinel Island lighthouse was the only one of its kind in Alaska. It comprised of a square wooden tower attached to the center of the westerly front of a keeper’s duplex, which was a large, two-story building with hipped cross gables. Atop the tower stood a 13-foot-tall, steel and glass lantern room that housed a fixed, fourth-order Fresnel lens. In addition to the lighthouse there were outbuildings and structures built on the 6.5-acre site. You can make overnight stays or helicopter or boat tours to enjoy the spectacular views of the Gastineau Channel and the lighthouse.
