Front entrance of the Great Bay Discovery Center

The Great Bay Discovery Center campus is our headquarters and a wonderful place to start your exploration of the bay. It’s also a gathering place for scientists, community members, and our partners.

Inside the visitor center, you’ll find interpretive exhibits about the estuary, salt marsh farming, plankton, tides, and research on the Bay. At the Discovery Tank, children have the chance to touch estuary animals such as horseshoe crabs, oysters, mudsnails, and more! 

Inside the great bay discovery center

The Hugh Gregg Coastal Conservation Center is a modern education facility with a meeting space and natural history exhibits. Built in the old New England post-and-beam style, this facility has several sustainable design features, including a geothermal heating and cooling system and composting toilets. Currently it is not available to rent for meetings or workshops.

Outside, a universally accessible, interpretative trail and boardwalk invites you to explore the surrounding hardwood forests, freshwater wetlands, and salt marshes. You can stand on the deck of a 19th century Gundalow replica, explore a replica Native American camp, or wander through the native gardens, and don’t forget to visit the natural play area near the parking lot!  If you start at the parking lot, head to the waterfront, then explore the boardwalk and woodland walk trails, you will walk about a mile.  For more info on the property the Sandy Point pages of the Great Bay Passport here.

Playing on the boat

Birders find this spot an excellent place to watch for wintering eagles migratory warblers, waterfowl, and nesting osprey. Many of our monitoring programs are conducted in the marsh in front of the center and there is a water quality monitoring station less than a mile (by boat) away.

Looking for an activity to do while exploring?  We have a couple of options:
1) Audio Tour-scan the QR code on the Audio Tour sign on the front door and listen to educational information as you explore.  You can also find it here.

2) Bayventure Grab N Go Activities- this year (likely through August 2021) we are offering Grab N Go activities perfect for families!  The activity kits are a free, exciting, and self-guided way for families to discover the outdoors! These activity kits will be changed weekly and weekly themes will be listed in a Facebook event and on our website on the calendar of events.  Read more about these fun kits in our blog post.

3) Outdoor scavenger hunts: this one is for kids and those new to exploring, this one is more advanced.

With the exception of service dogs, pets are prohibited on the boardwalk and in the facilities, but they are permitted at the boat launch/waterfront area. Please be a responsible pet owner and scoop the poop and dispose of the bag properly.

Bikes are not allowed on the boardwalk.

We are a non-smoking property, and a carry-in/carry-out property.  Whatever you pack in, please pack out and bring any recycling and trash home with you to dispose of properly.  Thank you for helping us keep this wonderful place clean, inviting, and well protected!

Please contact Kelle Loughlin for more information about the campus.
