Rising from the waters of Green Bay, Wisconsin, the Grassy Island Range Lights were built in 1872 to guide vessels safely through the busy port channel. This pair of range lights served mariners for decades before being deactivated. Now standing silent, the structures offer a striking reminder of Green Bay’s maritime heritage and the vital role Great Lakes navigation played in the region’s growth.

The lights are not open to the public and cannot be climbed, as they sit on a deteriorating island accessible only by boat. Golden hour and early morning provide the best photography conditions from the shoreline. Nearby, visitors can explore the National Railroad Museum, Green Bay Botanical Garden, and the vibrant waterfront district.
