Middle Sister Island Lighthouse
Location & Light Range
About Middle Sister Island Lighthouse
A white, square skeletal tower stands 23.5 meters tall on Middle Sister Island, guiding vessels on Lake Erie. The tower's focal height reaches 26 meters, and it emits a green flash every 4 seconds, visible for 14.5 nautical miles. This 4-hectare island lies in the western part of the lake, just north of the international boundary. The lighthouse is operational, though the island and tower are not open to the public. The island was listed for sale in 2025.
Why it matters: The lighthouse is critical for safe passage through the western end of Lake Erie, especially for vessels navigating near the international border, and helps delineate shipping lanes.
