ThunderFest & ThunderBolt

A ski trail and a winter celebration in the Berkshires

About ThunderFest

ThunderFest is the name of a winter festival in Adams, MA. It was born in 2012 as a downtown activity after the Thunderbolt Ski Race on Mount Greylock. Although the race hasn’t happened in a few years, this annual mid-winter celebration still continues!

ThunderFest features live music and tons of winter activities for adults, children, and families. Read more about ThunderFest and ThunderBolt below!

Thunderbolt and Its History

The Thunderbolt Ski Trail is a Class A backcountry ski trail that runs from the highest point in Massachusetts, the summit of Mount Greylock, to Greylock Glen. 

Constructed in the 1930s by the Civilian Conservation Corp, this challenging trail used to host international downhill races. The official record of 2′ 8.6″ set by Norwegian Olympian, Per Klippgen in 1948, still stands.

The trail fell into disuse after rope tows and ski lifts became common. However, a group of intrepid volunteers called the Thunderbolt Ski Runners have restored and maintain the trail. It is now a favorite with backcountry skiers and boarders.

In modern times, the Thunderbolt Ski Race took place every year for a while, weather permitting, before being put on hold during the COVID pandemic.

If you’re interested in backcountry cross-country skiing, nordic skiing, skate skiing, or snowshoeing, one of the best backcountry ski trails in New England is waiting for you in Adams, MA!
