Drumlin Farm is a Mass Audubon wildlife sanctuary and working farm near Concord and Lincoln. Trails cross fields, woods, and wetlands, while the farm area has animals such as pigs, cows, horses, and sheep.
It is especially good with children, but not only for them. The mix of farmyard, nature trails, and Audubon programming makes it a relaxed half-day outside the town's literary and Revolutionary War sights.
