The Boston Harbor has had its share of drama since its discovery by John Smith in 1614 (Boston Tea Party, anyone?), but these days, it’s smooth sailing when you include a boat cruise in your Boston sightseeing itinerary. The themes and varieties are numerous – for a wacky, or maybe quacky, time, a duck boat tour offers both land and water adventure. The amphibious boat will take you past major landmarks like Bunker Hill and the Fleet Center. A USS Constitution cruise takes you to the Charlestown Navy Yard to see “Old Ironsides” herself. The New England Lighthouse Cruise offers amazing scenery of the Boston-area coastline as you pass by some of the oldest lighthouses in the US. Dinner and brunch cruises allow you to enjoy the Boston skyline while you dine, and a sunset cruise sets a romantic mood – sip a cocktail on the deck and watch the city light up as the sun goes down.
