Mount Greylock via Bellows Pipe and Thunderbolt Trail

The trail starts from parking area up to AT via Old Summit Road. A little confusing with the skiing signs, but head east up to AT. Hike along AT to a point where Thunderbolt ties in, and make a push up to the summit of Greylock. Take the thunderbolt trail north until you reach the Appalachian trail (marked while), where you will turn left until you reach the Mount Greylock summit. The Thunderbolt Trail was originally a CCC built ski trail, and in 1936 hosted the United States Eastern Alpine Ski Championships. Its current course has been somewhat altered from the original, but is no less challenging. The Thunderbolt Foot Trail climbs gently west winding through the forest south of Hoxie Brook, and eventually the foot trail will intersect the old ski trail on your right. At about the half mile mark, the trail becomes considerably steeper and heads northwesterly towards the summit ridge. This stretch is quite broad and is recognizable as a steep, tree-lined ski run. At about the 1.5 mile mark the trail reaches the summit ridge, where you have a beautiful view upon the town of Adams from Hadley Lookout.
