From the Society for the Protection of New Hampshire's Forests:
Three different paths lead to the summit of Green Mountain, part of the Green Mountain State Forest, a block of land at the summit surrounded by the High Watch Preserve. Blueberries are often abundant near the summit in season. An 0.4 mile spur trail to an adjacent peak, Hanson Top, leaves from the Libby Road Trail, just a few hundred feet from the summit of Green Mountain. Hanson Top provides excellent views to the south and west from an exposed ledge.
You’ll find a small parking area, kiosk, and property sign at the Dearborn trailhead (not plowed in winter). This trailhead is at the end of a Class V (plowed) section of Hobbs Road, accessed from the Lord’s Hill section of Rt. 153 (Province Lake Road). The High Watch trailhead is at the end of High watch Road; park along the side of the road and look for the property sign that marks the trailhead (on your right at the end of the short dirt-road section). At the Libby Road Trailhead, you’ll find a locked bar gate. Please do not block the gate when parking here. This section of Libby Road is not maintained in the winter; however, you can park at the junction of Town House Road and Libby Road in winter and snowshoe in from there.
