Fort Wetherill State Park
Granite cliffs, military ruins, diving water, and harbor panoramas make this former coastal defense site beautiful, complicated, and physically hazardous.
Artwork inspired by Walter Francis Brown
Fort Wetherill’s batteries guarded the East Passage to Narragansett Bay. Today their concrete forms, graffiti, and overgrowth intersect with scuba access and steep coastal terrain. The park is compelling precisely because military geometry and ecological succession now occupy the same headland.
Treat fenced and closed structures as closed; unstable concrete and cliff edges are not invitations. Divers need local knowledge and appropriate support, while ordinary visitors should use marked overlooks and coves. Poison ivy, broken glass, and limited guardrails make wandering risky. From safe viewpoints, the alignment of batteries and channel clarifies why this particular headland mattered strategically.

Good to know
Abandoned structures may contain unstable surfaces, debris, and prohibited areas. This is not a supervised swimming beach; cold water, currents, depth, and boat traffic demand specialist judgment.
