The Trustees has been protecting the Massachusetts shores for over 100 years.

Beloved beaches, shorebirds, and historic oceanfront estates are all under our care, and we see thousands of visitors each year. In total we own and protect over 120 miles of coastline in Massachusetts with 35 properties including 75 miles of coastline located in 25 different communities, representing 16% of all protected coastline in MA, and more than any other single private landowner in the state. In the face of climate change and coastal development, we have a responsibility to champion and innovate, bringing a new energy and focus to bear for the future of our coastal places.

Explore our coastal reservations

We are proud to protect and steward 120 miles of shore in 25 of the state’s 78 coastal communities, including 26 miles of beaches and dunes, islands, 2,300 acres of salt marsh, and miles of rocky coasts and islands—all landscapes of extraordinary ecological value, and some of our most dynamic. We invite you to explore these special, ever-changing reservations, and experience the coast in new and active ways!
