Pleasant Valley Wildlife Sanctuary
Beaver ponds, hardwood forests, and sun-dappled meadows abound at this preserve run by the Massachusetts Audubon Society. Recent wildlife sightings are noted on whiteboards at the entrance and the visitor center, so you'll know what to watch for on the 7 miles of trails. These include loops that range in difficulty from a half-hour stroll around a pond to a three-hour mountain hike. Trails are also open in winter for snowshoeing. At the visitor center there's a nature play area for children.
