Willow Brook Farm lies at the confluence of the Pudding and Herring brooks in the Herring Brook Valley and is among the most diverse and interesting inland natural areas in Southeastern Massachusetts. The area is extremely productive for wildlife and conserves an unusual freshwater tidal marsh, a habitat type of both state and global significance. Tidal fluctuations can be observed here, some 11 miles upstream from the Atlantic Ocean. Within the valley lies a wilderness of more than 2,000 acres, which is a headwater area of the North River, and critical to water quality downstream. This unspoiled area, in which no development can be seen, is surprising given that the valley is surrounded by suburban towns and is only 30 miles from Boston. The diversity and interesting topography encourage visitors to return often to sample the changing seasons.

Begin your walk at the informational kiosk near the entrance. Trails and ancient farm lanes wander through old fields and dense woods that include old-growth trees. This area provides habitats for a wide range of wetland species and an abundance of wildlife, including several rare species and several “Partners in Flight” watch-list birds. River otter, coyote, beaver, woodcock, ruffed grouse, and several amphibian species have been seen on the preserve.
