The South Farm Preserve is made up of two fields each with a trail around the perimeter and woodland trails at the southern end of the south trail. The fields are connected by a trail. The preserve was originally a working farm and there is a restored sheep barn and the firebox of a sauna. On the far-right side of the north field, just off Old Coach Road, are the remains of the house, garden, and some old fruit trees. There is also a historic cemetery where many members of the Card family are buried. Most graves date back to the 1800s.

The trails are cut regularly, but the fields are home to birds and butterflies, and so are not cut until late in the year.
