Outer Island, located off of the coast of Branford, is the southernmost of the Thimble Islands. It was privately owned until 1995, when Elizabeth Hird donated it to the refuge to protect the island’s natural resources and provide access to education and research. This five-acre island, composed of granite outcroppings, boulder and cobble beaches in the intertidal zone, and small salt marshes, provides a habitat for migratory birds and marine life and is a critical pollinator stopover site.

Outer Island is especially popular with families, schools, and local day camps. PRO TIP: When visiting Outer Island or other island units, plan your visit at lower tides to explore and find creatures in the intertidal zone.
