Standing sentinel on the St. Croix River since 1892, Whitlocks Mill Light marks the northernmost lighthouse on the Atlantic coast of the United States. This active aid to navigation guides vessels along the river that forms the border between Maine and New Brunswick, Canada.
The lighthouse remains closed to public access, but photographers can capture striking images from nearby vantage points. Golden hour provides the best lighting, with autumn foliage creating a spectacular backdrop.
Visitors to the area can explore St. Croix Island International Historic Site, commemorating the first French settlement in North America, or cross into Canada to experience the charming town of St. Stephen. The Downeast region offers additional coastal beauty and rich maritime heritage.
