Straitsmouth Island Light

Straitsmouth Island Light stands 11 meters tall with a white cylindrical tower and black lantern that marks the harbor entrance from the Atlantic Ocean. The structure sits on a small rocky island covered with low vegetation and surrounded by water.

The original tower from 1835 was replaced in 1896, and the lighthouse became automated in 1967 through an underwater power cable from the mainland. These changes reflect advances in lighthouse technology and remote operation over the decades.

The island hosts rare bird species that you can observe while walking quietly along the trails. For the local community, this place represents protection of coastal wildlife and natural habitats.

Visitors need to book boat tours departing from Granite Pier, with access limited to summer months from June to August. Bring weather-appropriate clothing since the island is exposed to ocean conditions and weather can change quickly.

The lighthouse property transferred to Rockport in 2010 and is now part of a larger protected natural area managed by the Massachusetts Audubon Society. The surrounding grounds offer visitors rare chances to see seabirds in their natural setting.
