Explore the Secluded Gilbert Head Estate for Sale on Long Island, Maine

The allure of Maine’s coastal islands has long captivated those seeking a retreat from the ordinary. Among these, the Gilbert Head estate on Long Island stands out as a remarkable offering. This sprawling 25-acre property, accessible only by boat, is now on the market for $3.8 million, presenting a unique opportunity to own a piece of Maine’s rich maritime history.

The estate’s main house, built in 1862, boasts five bedrooms, three bathrooms, and over 3,300 square feet of living space. The property also includes a small boathouse, barn, and studio building, all nestled within a landscape of meadows, wooded trails, and a small beach that reveals itself at low tide.

The Historic Charm of Gilbert Head

The Gilbert Head estate has been a witness to generations of island life. Before the current sellers, renowned artist Stephen Etnier and his wife, Elizabeth, called this island home. Elizabeth’s book about their time here offers a glimpse into the estate’s past, describing the family’s seasonal life and the cozy retreat the smaller rooms provided during the shoulder seasons.

The current sellers have meticulously maintained and updated the home over the past 22 years, ensuring it retains its historic charm while offering modern amenities. Recent upgrades include a new pier, roof, and water heater and pressure system. The estate is equipped with electricity, internet access, wood-burning stoves, and propane, making it suitable for year-round living, although it has historically been used as a seasonal retreat.

A Haven of Privacy and Natural Beauty

Situated at the mouth of the Kennebec River, the Gilbert Head estate offers stunning views of Fort Popham, Popham Beach, and the river’s bustling boat traffic. The property’s deep-water pier, constructed from Deer Isle granite, provides easy access for boats. Despite its seclusion, the estate is not entirely private; a handful of residents live on the island, and conservation agreements preserve the land from further development.

The estate’s remote location enhances its appeal for those seeking privacy and a deep connection with nature. The sellers have enjoyed the estate’s natural wonders, from watching seals and osprey to picking blueberries and fishing. The property’s ecosystem is a constant source of fascination, offering a front-row seat to the island’s wildlife and the comings and goings of boats, including the occasional destroyer from Bath Iron Works.

Exploring Long Island and Beyond

Long Island is just one of several offshore islands in Maine that support year-round communities. Isle au Haut, another remote island, is part of Acadia National Park and accessible only by boat. This island offers spectacular hiking trails and anchorages, attracting cruisers and boaters seeking a taste of Maine’s archetypal beauty.

Approaching Isle au Haut is straightforward, with well-positioned navigation markers guiding the way. The island’s main anchorage, Point Lookout, offers breathtaking views of the Camden Hills. The island’s village provides essential services, including a general store and post office, while the nearby town of Stonington offers dining options and shopping.

Both Gilbert Head and Isle au Haut exemplify the unique allure of Maine’s coastal islands. These properties offer a rare opportunity to embrace a lifestyle steeped in history, natural beauty, and seclusion. Whether as a seasonal retreat or a year-round home, these island estates promise an unparalleled connection with the sea and the rich tapestry of life that unfolds along Maine’s coast.
