What is it? Boston is no Denver, but there are still a couple of mountains (glorified hills, really) to climb. Just a few minutes outside of the city proper is a 7,000-acre reservation with 125 miles of pristine hiking trails.
Why we love it: Climb to the top of Great Blue Hill and enjoy the unmatched view of the Boston skyline from the Eliot Observation Tower—just prepare to share the scenery with crowds during warmer months and peak autumn.
Time Out tip: For a view of the skyline with fewer crowds, check out the Chickatawbut Overlook. The Skyline Trail is challenging, while the Ponkapoag Pond Loop offers a leisurely stroll along the woodlands marked by majestic pine and hemlock trees.
Address: 695 Hillside St, Milton, MA 02186
Opening hours: Daily 6:30am–7pm
Expect to pay: The park is free to enter and enjoy, and parking is complimentary at a variety of lots within the grounds, including the Houghton's Pond parking lot.
