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.

Great view atop the mountain. I️ would consider this a challenging hike, becoming more challenging towards the top. Perfect November day.

What a hike! I accidentally got off trail (not entirely atypical for me) and ended up doing a straight vertical incline UP a ski racing trail. Plus side? I bumped into a ski group clearing the trail for their race in February and they shared a delish craft beer with me. Downside? I was practically climbing up a mountain with a full beer in me ;). Slow and steady wins the race, I say. Weather was perfect (warm for the fall), amazing views, and overall excellent hike. P.S. - went down the right trail on the way down...what a difference!
