Now joined to the mainland by a strip of land, visitors are welcome to Castle Island year-round. From Memorial Day to Labor Day, guided tours of Fort Independence run on Saturdays and Sundays for those who wish to learn more about this historic and stunning land.
There a path that stretches around the Boston Harbor, creating an artificial pond called Pleasure Bay. There is also a small circular park called the "Sugar Bowl" on the furthest point of the path. The area is great for strollers, joggers, bikers, and observers/explorers. And for history buffs, for whom the guided tour will serve well.
This place as been a fort since 1634.
