Head to Spectacle Island for some fun and recreation in the sun. From hiking and biking to swimming and boating, there's a variety of things you can do here that will get your blood pumping. Before or after your workout, stop by the visitor center to explore exhibits about the island's history and development. You can also get a great look at the city from the hilltop.
While you're hanging out in the Boston Public Garden, take a ride on the city's signature Swan Boats. The boats are the only ones of their kind in the world and they float the waters of the Public Garden lagoon. A ride on one of these boats is the best way to see all of the attractions in and around America's first botanical garden.
Visit a place where an important event took place. The Boston Massacre site is where the legendary conflict between the colonists and British soldiers took place; some would even say that this event was one of the many catalysts to the American Revolution.
