Spend some time exploring Adams National Historical Park. The park is where several historic homes are located, including the birthplaces of John Adams and John Quincy Adams, and the United First Parish Church where both Presidents are entombed. Aside from the houses, there are plenty of attractions to see at this park so sign up for a tour or go on an excursion of your own.
Grab your skis and hit the slopes at the Blue Hills Ski Area. Seven trails and a drop over 300 feet comprise this recreation area. If you're not so great with a set of skis, Blue Hills offers a variety of lessons.
