Watch the opening battle of the American Revolution take place right before your eyes at Minute Man National Historical Park. This hallowed ground is where the war began and where it is relived through reenactments. These demonstrations aren't the only things to do at the park though; explore the visitors center, walk down Battle Road Trail, check out the Hartwell Tavern and The Wayside and other park attractions.
Explore the Great Brook Farm State Park on over 20 miles of recreation trails. The trails throughout the park are perfect for hiking, biking, and horseback riding, and in the winter they provide the perfect path for skiing. Along with plenty of ways to stretch your legs and enjoy nature, the park offers a look at what the classic eastern Massachusetts agricultural landscape is like.
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.
