The Ed Woodsum Preserve includes all of 985-acre Marshall Island, the largest undeveloped island on America's eastern seaboard. The preserve was acquired by the Maine Coast Heritage Trust (MCHT) in 2003, thanks to the generosity of private donors and the State's Land for Maine's Future Program. In the years that have followed, the Trust has developed 9.2 miles of hiking trails that allow visitors to explore much of the island. However, most visitors to Marshall are drawn to an alluring beach located within Sand Cove on the island's southeastern shore. This sandy expanse is a popular summer destination for recreational boaters and residents of nearby communities.

Marshall is forested predominately with spruce species and an occasional hardwood. Throughout the island there is a network of interconnected wetlands. Nearly the entire shoreline consists of bold granite ledge and cobble beaches. Numerous species of birds are drawn to the island each year. In addition to migratory visitors, the island is home to eagles and many resident songbirds.

Caution should be taken while hiking the island's rugged shoreline. While MCHT employs summer caretakers on the island from July through Labor Day, no services are available and cell phone coverage is spotty. There are few places along Maine's coast as isolated, wild, and beautiful as Marshall Island.
