Hidden away in the rugged Osage Hills of Northeastern Oklahoma, Woolaroc was established in 1925 as the ranch retreat of oilman Frank Phillips. The ranch is a 3,700-acre wildlife preserve, home to many species of native and exotic wildlife, such as bison, elk, and longhorn cattle. Woolaroc is also a world-class museum with an outstanding collection of western art and artifacts, Native American material, one of the finest collections of Colt firearms in the world, and so much more.
