Set amidst more than 1,000 lush acres in the Berkshires, Pleasant Valley’s varied trails wind through forests, meadows, wetlands, and along the slopes of Lenox Mountain, making this site an excellent location for easy-to-strenuous hiking. While exploring, there’s a good chance you will see evidence of the sanctuary’s most visible wildlife resident, the beaver, via dams, dens, or lodges.
After being absent in Massachusetts for more than 200 years, three beavers were reintroduced to Pleasant Valley in 1932. They quickly got to work creating the dams and ponds you see today. Get to know beavers—nature's wetland architects!
Pleasant Valley is celebrating 90 years of conservation in the Berkshires! We're planning a wide variety of fun events and programs in honor of our anniversary, all of which will be open to the public and people of all ages and abilities. Next event is August 17!
