The farm and buildings at Great Brook Farm comprise a classic eastern Massachusetts agricultural landscape. The arrangement of open fields, sturdy walls, diversified woodlands and historic structures are significant images of our agricultural past. An active dairy farm operates year-round and guided barn tours are available from May to October. Amidst the beautiful scenery lie 20 miles of trails for hiking, bicycling and horseback riding. Notable Native American sites can be seen from these paths. During the winter months, trail-grooming allows skiing enthusiasts to take part in cross-country skiing. One of the farm buildings has been converted to a ski rental concession. Meadow Pond has a canoe launch and is ideal for fishing. Dogs can be off leash except near ice cream stand/parking lot. Lots of trails/fields and other dog walkers. Also ice cream stand in the park! There are horses so be sure to bring a leash with you. Location: 984 Lowell Street.
