Visitors to the Dix anchorage can walk around this historic island. Land your dinghy on the sandy NE beach opposite the granite piers on High Island and follow the well-marked paths around Dix. Like many other Maine Islands, Dix was heavily quarried for its distinctive granite. It was the home of some 2000 residents in its heyday around 1875. Both the New York and Philadelphia post offices were built from Dix Island Granite. Visitors will see many old foundations, including those of the Aberdeen and Shamrock boarding houses each holding about 500 men. There are several abandoned quarries now filled with water, many beautifully granite-lined dug wells, a couple of dilapidated old vehicles, and abundant bird-life. The paths are designed to avoid the private cabins scattered around Dix Island.
High Island, easily identified by its bold granite piers, was recently purchased by a private party. Some clearing and construction are underway. It is no longer accessible without permission.
Birch Island is owned by one of the Dix Island families, and visitors are welcome to its sandy shores. Birch Island is small but has perhaps the nicest white sand beaches in the area, affording wonderful picnicking and beach-combing.
