Spend some time hanging out in the country's oldest park. The 50-acre Boston Common is the anchor for the Emerald Necklace park system and is the starting place of the famous Freedom Trail. There are quite a few monuments throughout the park, and several outdoor events take place in the Common throughout the year.
While in Boston, be sure to visit the Bunker Hill Monument, one of America's oldest standing monuments. This impressive landmark was constructed in the mid 1800s to commemorate the first battle of the American Revolution. The monument is accompanied by an exhibit hall and a museum located across the street.
The Charles River Esplanade stretches along three miles of the beautiful Charles River and surrounding attractions. This spot is perfect for relaxating outdoors and enjoying a picnic, fishing, taking a gondola ride, or just sprawling out on a blanket and watching the river roll by. There are also several scheduled events here like fitness classes and festivals.
