Plan a trip to Boston

If you want to experience a true Irish pub, real cannoli, avant-garde art studios, and some of the finest jazz music you'll ever hear all in one place, Boston has you covered. It’s a walking town, so prepare to hike the maze of cobblestone streets. Take the subways anywhere you can't walk to; the city remodeled them with commissioned local artwork, and they are an exploration wonder unto themselves. Explore lovely Boston Public Garden right in the middle of the city, complete with Belgian elm, Kwanzan cherry trees, and swan boats. Walk the historic downtown Freedom Trail, and climb Bunker Hill for incredible city views. Experience the European feel of boutique-browsing on elegant Beacon Hill, as you walk by gas-lit wrought-iron street lanterns and Victorian era homes. Quincy Market, designed in 1824 in the Greek Revival style, gives you top-talent street theater performances and the largest international food hall in New England.
