The Civilian Conservation Corps built Mount Greylock’s famous Thunderbolt Trail in 1934, when skiing was taking off as a popular recreational activity. This challenging ski run drops more than 2,000 vertical feet in just under two miles, from the summit to the base.
The trail was rated a Class A expert run and hosted many Massachusetts downhill ski championship races, including the premier United States Eastern Amateur Ski Association Championships in 1938 and 1940. Today, backcountry skiers looking for a unique physical challenge use the trail at their own risk. It is also used by hikers and a portion of it overlaps the Appalachian Trail.
Please note: The Mount Greylock Scenic Byway is closed to vehicles from mid-October through June. Hiking, snowshoeing, cross-country skiing and snowmobiling are still permitted.
