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.
You won't be at a loss for recreation at the Hale Reservation. There's plenty of room for fun here! Come for the day or plan a camping trip; while you're here, check out the playground, explore recreation trails, have a picnic in the open field, or try fishing in one of the three nearby ponds.
