Nestled on 70 acres of oceanfront property in Rockport, Maine, the cottages at Oakland Seashore are the perfect choice for a romantic getaway, vacation with friends, or a family gathering.

Reminiscent of a bygone era, these cottages are simple and provisioned with the basics, but have the most remarkable ocean views.
