Fork Factory Brook, Medfield
Fork Factory Brook is much smaller, only 135 acres. However, it's completely different from Rocky Woods which is where you'll park. Fork Factory Brook contains about 2.5 miles of trails but they're all tight twisty singletracks. Fork Factory's trails are fun to ride in both directions. The contrast between the two areas is startling. And for a complete day's riding I'd recommend doing both.
Fork Factory Brook's singletracks edge around a hayfield on Long Acre farm and then dive into the woods for a trip to the site of an old mill. The singletracks wind about, rarely going for more than a few yards without a twist or a turn and some are quite tight. IE: Your shoulders will come in contact with a lot of brush as the surrounding woods are encroaching onto a number of the trails. This makes for a completely different experience than the wide open hilly trails in Rocky Woods.
