      The Greylock Glen area covers 1,000 acres in the shadow of Mount Greylock, which overlooks the scenic Berkshire County town of Adams. This area is in the process of being developed by the town and the Commonwealth in partnership with Berkshire NEMBA and the Thunderbolt Ski Runners as a model for outdoor recreation, environmental conservation, and education. The new development of this area will include hiking and other pedestrian trails, downhill backcountry skiing (including the historic Thunderbolt Ski Trail), single-track mountain biking and running trails, cross-country skiing trails, and snowmobile connections.
