Keweenaw Waterway Upper Entrance Light

Keweenaw Waterway Upper Entrance Light is a lighthouse in McLain State Park featuring a square tower mounted on a cylindrical base, standing 21 meters tall at the eastern breakwater entrance. The structure rests on interlocking steel sheet piling filled with rock, with a signal building positioned beneath the main tower.

The light began operation in 1950 as a replacement for an earlier structure from 1874, marking a technological shift for regional waterway navigation. Automated systems were added during the 1970s to improve its operational efficiency.

The light stands as a centerpiece of local maritime character, reflecting design choices from its era of construction. This structure shapes how visitors understand the region's connection to water and navigation history.

The light can be viewed from McLain State Park, located west of Hancock along Highway 203. Interior access is not available, but the exterior can be seen clearly from the waterfront area.

Beneath the tower sits a large signal building with a square footprint, a feature many visitors overlook. This structure was essential for guiding ships through fog and difficult weather conditions on the waterway.
