As soon as spring comes to Boston, six iconic swan boats float out into the Public Garden's lagoon. Everyone enjoys having a ride—local kids and adults, as well as tourists. The peaceful and scenic voyage is a short unwinding break, and quite helpful after a hectic, busy day. This is a great chance to some to relive the simple joys of their childhood. Although the voyage only lasts for 15 minutes, it may have a lasting impression on your day. The first swan boats appeared in Boston back in 1877. The oldest surviving one dates back to 1918. Everyone can enjoy a picturesque ride from mid-April to mid-September.
