Formerly known as Kilbourn Hill, Dexter Drumlin is 311-feet high and situated within a 38-acre open space reservation which includes a small tributary of the Nashua River.

The reservation is a graceful, open meadow managed for ground-nesting birds (though hay is cut from the meadow after the young birds have fledged from their nests). A narrow, one-mile mowed footpath leads over the top and around the drumlin—the ideal way to experience its scenic views. A favorite local spot for winter sledding, it is owned and stewarded by The Trustees.
