Head out on a Boston Lobster Tour to fish for lobster and learn about the Boston Harbor. Along with a narrated history of the area, you'll get to see lobsters, sea urchins, star fish, and crabs up close. Bring your camera because your trip on the water offers some pretty great views of the city.
Head to the Back Bay Fens and hang out next to a beautiful freshwater marsh. Along with the marsh, this link in the Emerald Necklace park system is home to ball fields, a wartime “Victory Garden” that was established in 1941, and the popular Kelleher Rose Garden, among other outdoor attractions. While you're exploring the park, be sure to pay respects at the World War II, Vietnam, and Korean War memorials that reside in the park.
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.
See the Boston Red Sox in action during their next game at Fenway Park. The Red Sox has been a sports institution since the franchise was founded in 1901. The Sox have won MLB's highest honor, the World Series, seven times, and have claimed 12 American League pennants as well. Get your tickets early; every home game since 2003 has been sold out.
