Great Bay Discovery Center

In 1993, the Great Bay Discovery Center (formerly known as Sandy Point) was constructed on the shores of Great Bay. Located in Greenland, NH, it serves as the education headquarters of the Great Bay National Estuarine Research Reserve.

Inside the Discovery Center, visitors are treated to interpretive exhibits about the Great Bay Estuary and the amazing creatures that call it home. Children can get their hands wet in an estuarine discovery tank as they learn about horseshoe crabs, oysters, mud snails and more! Interactive displays about salt marsh farming, salmon migration, plankton, tides and research on the Bay, allow children and adults alike to learn about the Estuary.

The center is open to the public 10am-4pm, Wednesdays through Sundays, May-September. We are open weekends only October, and closed November through April. We reopened to the public Wednesday May 3rd. The grounds are open year round, dawn to dusk.
