Greenleaf State Park is tucked in the hills of eastern Oklahoma and offers spectacular scenery as a family-friendly park. It includes Greenleaf Lake, cabins, campgrounds, family recreation facilities and nature hiking trails. The lake cabins and other facilities were built in the 1930s by the Works Progress Administration. The original native stone buildings remain a lasting tribute to the workers who built them. The park has 16 rustic WPA-built cabins equipped with bathrooms, kitchens with full-size appliances, heat and air.
