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, with our last open day being October 25th for the 2015 season. The grounds are open year round, dawn to dusk.
The Hugh Gregg Coastal Conservation Center, constructed in 2005, is a modern education facility that provides valuable meeting space as well as exhibits on the upland habitats of the Great Bay Watershed. Built in the old New England post and beam style barn, this facility has several sustainable design features, including a geothermal heating and cooling system and composting toilets.
At this time it is not available to rent for meetings or workshops.
The exhibits focus on the upland habitats of Great Bay and include a life-size diorama depicting how the land was shaped by Native Americans and the early settlers.
On the lower level, there is a Special Collections room featuring artifacts of Great Bay and seacoast New Hampshire with a focus on hunting and fishing. The Special Collections room will be open the first Sunday of each month (excluding July) from May to October 2015, from 10am-1pm.
The grounds are beautifully landscaped and include a waterfall and stream feature that connects the two buildings. A universally accessible trail and boardwalk allow visitors to explore a variety of habitats including upland hardwood forests, freshwater wetlands, salt marsh and mudflats. Newly installed interpretive signage allows visitors to learn about the diverse habitats found along Great Bay.
Visitors can stand on the deck of a 19th century Gundalow replica, explore a replica Native American camp or wander through the native gardens surrounding the center. Birders find the Discovery Center an excellent location to watch for Great Bay's wintering eagle population, migratory warblers, waterfowl, and nesting pairs of osprey.
With the exception of service dogs, pets are prohibited on the boardwalk and in the facilities.
Pets are permitted at the boat launch.
