• Keep Popponesset Bay Strong

    Popponesset Spit protects our homes, beaches, and wildlife. Erosion threatens it every year — but together, we can restore and preserve this special place.

  • You’re Invited to the SPB Annual Summer Fundraiser!

    Join us for Save Popponesset Bay’s annual summer fundraiser — tropical cocktails, dinner, live band, hula dancing, and new SPB merch. It’s always a sell-out!

  • No Dogs on the Spit, Please!

    Our federally protected Piping Plovers and Terns have returned to nest for the 2025 season. To keep them safe, no dogs are allowed on the Spit starting April 1. Please respect the roped-off areas and help give these special birds a safe place to raise their chicks. Thank you for caring for our wildlife!

Save Popponesset Bay

Save Popponesset Bay is the owner of 3/4 of the Spit, with the eastern 1/4, owned by Mass Audubon. The Popponesset Spit is a fragile, natural barrier peninsula and wildlife sanctuary that protects Popponesset Bay from Nantucket Sound, Mashpee’s watershed, and other land throughout Mashpee and Cotuit. Since its most depleted state in 2012, Save Popponesset Bay has raised and invested hundreds of thousands of dollars for trucking sand, dredging sand from the Popponesset Bay Approach Channel leading to Nantucket Sound, and the purchasing/planting of dune grass to anchor the new sand for the Spit. We also provide security in partnership with PBA and our partner Mass Audubon. These dredging and construction activities are critical to keeping the area healthy and safe for all that enjoy it.
