Be sure and bring your binoculars to this bird-watchers paradise.



One of East Hampton's most scenic and diverse tidal marsh systems, Accabonac Harbor is a bird-watcher's paradise.

Accabonac was donated to The Nature Conservancy in 1968 by one of the founders of the South Fork-Shelter Island Chapter, Frederic E. Lake, and his wife Muriel. The 29-acre Merrill Lake Sanctuary at Accabonac Harbor is one of the chapter's first preserves.



Parts of the preserve are closed during osprey nesting season (May through July).


A wide variety of animals and plants inhabit the preserve, including red fox, piping plovers, least terns, nesting osprey, sea lavender, black grass and marsh elder.
