Located on the shore of the Long Island Sound, along a migratory flyway, this 179-acre sanctuary is home to a great diversity of marine life. In winter months, the 85-acre lake, a mixture of salt and fresh water, hosts over 5,000 ducks. The sanctuary has been recognized by the national Audubon Society of New York as an Important Bird Area due to its significant habitats and flyway.

There are three miles of trails through forest and field. Along the half-mile of publicly accessible shore, the intertidal habitat harbors a wide diversity of plants and animals.

Restrooms, maps and information are available at the nature center. The building also houses a small number of exhibits on the ecology of the area. Checklists of seasonally distinct bird species are available.
