Parking for this trail is the last right on Gould Road before the private property at the end. Take the trail north into the woods and follow left up towards the obvious peak. The trail will intersect, meet up with, and diverge from the Thunderbolt Ski Trail. These crossings are well marked, so just look for the signs.
At about 2,200' (1.3 miles) into the trail, the Bellows Pipe Trail splits shortly before a trail-side shelter. Take the trail to the right if you intend to follow Notch Brook
up north towards North Adams. Just after the split in the trail, the trail will begin to descend back down the valley towards the Notch Reservoir.
