Once a landfill, Spectacle Island is now a beautiful 105-acre outdoor destination where visitors can enjoy everything from hiking to swimming. Just a 15-minute ferry ride from Boston, the island is one of 34 that fall under the auspices of the Boston Harbor Islands National Recreation Area. A five-mile walking trail begins at the Spectacle Island Visitor Center, leading past protected wildlife areas before arriving atop a 157-foot hill that offers stunning views of the harbor and the Boston skyline. Solar panels provide power to the "green" center, which also features compost toilet system in the public restrooms. Outside, there is a covered patio is filled with rocking chairs and public showers to rinse off.
