Welcome to the Diamond Cove Website!

Spectacular sunsets, sheltered beaches, acres of old-growth forest. Diamond Cove, on Great Diamond Island in Casco Bay, is Maine’s premier island community. We have waterfront property with breathtaking views - the ideal place to build your dream house. Or you can purchase a 19th-century home with National Register standing. Enjoy tennis, sailing, a heated pool and gourmet dining. Wonderfully secluded, yet just a short ferry ride from Portland, Maine’s largest city.
