Climb up Thoreau’s favorite Bellows Pipe Trail, enjoy the summit, then descend the curvy, heavily wooded Gould Trail. This is a steep, relentless, and rewarding ascent - shorter than climbing the mountain from the Williamstown side but still demanding. It is only suitable for people with strong knees, ankles, and hearts and some confidence on the trail. Leashed dogs accustomed to long hikes are welcome. Bring snacks, water, and a warm layer for the summit. strenuous, 7+ miles, 2200’, 4-5 hours No rain date. Meet at KI at 10 a.m. to carpool or at the trailhead at Greylock Glen around 10:40.
