On its way to the Quabbin Reservoir, the Middle Branch of the Swift River cascades roughly 12 feet into an intriguing woodland pool at the bottom of a secluded gorge with 70 foot walls. A little further downstream you will find the foundation of a historic mill, giving you a glimpse of the industrial history of this site.

Along a short, quarter-mile trail, you have two choices: go left and explore the enchanting waterfall, or head right to follow the stream as it tumbles through large boulders past the site of an old mill. Be sure to watch your children closely as there are steep drops and rocky terrain throughout this reservation.

FREE to all. Open sunrise to sunset.
