Duke Farms is a 2,700 acre farm formerly owned by tobacco and hydro-power magnate James Duke and his daughter Doris Duke. Through demonstrations, research and educational programs, Duke Farms hopes to inspire a new approach to conservation and sustainable living. Various activities are available for visitors of all ages, including geocaching, horticultural programs and organic gardening classes, and for little ones, there's the Family Wonder Walk.
