Thompson Island

Island in Boston Harbor Islands

Thompson Island was settled as early as 1626 by a Scotsman, David Thompson, who set up a trading post to do business with the Neponset Indians. Today this island is privately owned by Thompson Island Outward Bound, a nonprofit organization that develops fun and challenging physical adventures, especially for training and developing leadership skills. As such, the public can explore its 200-plus acres only on weekends, when it’s wonderful for walking, fishing and birding.
