Kelly Farm is the oldest farm in Bonney Lake. Established in 1864 by William B. Kelly, it was a working farm for over a hundred years, producing dairy, hops, fruits and vegetables. Since it's 2009 restoration, the farm has been open for special occasions, such as weddings. Amid the 150 acres of groomed farmland, there is a hay barn for hosting large parties and a farmhouse that has been converted into a bridal cottage.
