Locke Pond is a bucolic, remote-feeling body of water in the Whipple Hill Conservation Area that straddles Winchester and Lexington. Many people who hike around Whipple Hill never even make it down to Locke Pond, as the sweeping views from the hill are often enough for folks who come to this rugged area northwest of Boston.
One particularly nice approach to Locke Pond is from the aforementioned Whipple Hill. Park at the little pulloff on Johnson Road right where Winchester and Lexington meet, hike the few hundred feet up to the top of Whipple Hill, then go left from the summit, descending into the woods along a switchback trail that eventually straightens out, ending at a ravine just north of the pond. From here it is a very short walk to Locke Pond, where a number of trails afford excellent views.
