Visitor & Tour Information: The St. Croix Historical Society owns the tower, but the house is privately owned. The grounds, dwelling and tower are closed to visitors. Since the keeper's house is a private residence, the best place to view the lighthouse is from a roadside picnic area along Route 1, about 2.5 miles south of Calais. The tower's original fourth-order Fresnel lens is on display at the Maine Lighthouse Museum in Rockland, Maine.
Lighthouse Trivia: The lighthouse is named after Colin C. Whitlock, a local who tended the lantern that preceded it. Whitlock also owned a mill nearby, which is why it was named "Whitlock's Mill."
