The original lighthouse tower at this location was constructed in 1808 as one of the first in the United States, later replaced by the current cast-iron structure.
The beach is a critical habitat for nesting piping plovers, a federally threatened shorebird species.
Shifting sandbars and heavy surf at this location are colloquially referred to as 'The Cut' due to historical storm-driven breaches.
The U.S. Coast Guard maintains the Chatham Light as an active aid to navigation.
Marine biologists frequently monitor the area as a primary shark aggregation site within the Atlantic white shark nursery.
Lighthouse Beach in Chatham, Massachusetts, is anchored by the active Chatham Light, which has guided mariners along the treacherous shoals of the elbow of Cape Cod since 1877. The beach is a protected barrier spit defined by shifting sands, strong currents, and significant coastal erosion. It is part of the Monomoy National Wildlife Refuge ecosystem, often serving as a haul-out site for local grey and harbor seal populations. The view from the beach encompasses the entrance to Chatham Harbor and the Atlantic Ocean. Swimming is strictly regulated and discouraged due to powerful rip currents and a high concentration of predatory sharks frequenting the area. The site is characterized by an expansive sandbar that changes morphology after major storms.

Prioritize viewing the ocean from the sand rather than entering the water, as rip currents here are dangerous.
Wear sturdy walking shoes if you plan to navigate the soft, deep sand near the shoreline.
Bring binoculars to scan the water for harbor seals often visible resting on nearby sandbars.
Do not attempt to swim in the deep channels or during high surf conditions due to intense rip currents.
The lighthouse tower is occasionally open for public tours on limited dates during summer months, but the beach itself is accessible year-round.
Stay behind roped-off areas during bird nesting season; follow all posted warnings regarding shark activity.
