Marking: White Blazes

The Marlboro Trail serves as one of the primary routes to the summit of Monadnock and the main access from the westerly side of the mountain. About 0.2 miles form the summit, the trail merges with the Dublin Trail into a single route. 

Parking is available at the Marlboro Trailhead located on Shaker Farm Road, about 0.7 miles from Route 124.
