Pleasant Valley’s thriving beaver population is one of the many fascinating features of this sanctuary. When you walk along Yokun Brook, take note of the “lodges” of tree branches and mud, where these nocturnal creatures spend their days. Salamander migrations are a major spring event along West Mountain Road. Seven miles of trails that wind through hardwood forest, meadows, wetlands, and along the slopes of Lenox Mountain make this site an excellent location for hiking. Canoe trips are offered regularly on the Housatonic River and area lakes from mid-May through Colombus Day. This sanctuary has the following universally accessible facilities: Restrooms (Education Builiding), All Persons Trail, Barn, Education Center.
