Waters Farm is a 1757 homestead and preserve with roughly 120 acres overlooking Lake Manchaug. The loop is about half wooded trail, some along the lake, and half open pasture.
The festival day features live music, food trucks, kids activities and games, and a Halloween costume contest. Festival admission prices are listed for adults, children, and seniors. The event awards a single custom brand item to the last runner standing; other finishers receive a themed shirt. Visit the organization's website for the most recent information.
