Middlesex Fells is as close to wilderness as it can get for a reservation less than 30 minutes away from one of the country’s largest cities. Touring the Fells on the Skyline Trail, you may sometimes believe you are deep in the woods of New Hampshire. Indeed, do not mistake the Skyline Trail for a quick afternoon walk. At about 7 miles in length, it is a real hike that can take most of a day if you like to stop frequently.
