Hiking

Embark on a journey through diverse landscapes on the Mount Greylock and Stony Ledge via Hopper and Haley Farm Trails, a challenging 8.6-mile (13.8 km) hike that takes you from open fields into dense forests and up steep, rocky ascents. You'll be treated to stunning views into "The Hopper," a unique glacial valley, from the Stony Ledge viewpoint, and eventually reach the summit of Mount Greylock, Massachusetts' highest peak, for expansive panoramas.

This moderate to strenuous route involves a substantial 2497 feet (761 metres) of elevation gain and typically takes around 4 hours and 44 minutes to complete.

Beyond the physical challenge, this trail offers a chance to experience a section of the iconic Appalachian Trail. The area also boasts historical significance, with the Hopper Trail originally opened by Williams College students in 1830. The unique glacial valley known as "The Hopper" is a geological marvel, making the views from Stony Ledge particularly special.
