Greenleaf State Park is located near Braggs, Oklahoma, and is situated around the 930-acre (3.8 km2) Greenleaf Lake. Greenleaf Lake was built in the late 1930s. There is an 18-mile (29 km) hiking trail that begins inside the park and weaves its way around Greenleaf lake and into the adjacent government land of Camp Gruber.
Greenleaf State Park is one of Oklahoma's original seven parks and one of its most scenic and family-oriented. The park includes Lake Greenleaf as well as cabins, campgrounds, family recreation facilities and nature hiking trails.
The lake cabins and other facilities at Greenleaf State Park were built in the 1930s by the CCC, WPA and German prisoners-of-war. The original buildings, constructed of native stone, remain a lasting and beautiful tribute to those who built them. The park has 14 cabins with bathrooms, kitchens, heat and air, dishes and linens. All cabins have satellite television. The cabins are approximately 350 sq ft (33 m2) in size. The park also has the "Cabin on the Lake," which is a handicapped accessible cabin designed to meet the challenges of the physically disabled.
State parks or provincial parks are parks or other protected areas managed at the sub-national level within those nations which use "state" or "province" as a political subdivision. State parks are typically established by a state to preserve a location on account of its natural beauty, historic interest, or recreational potential. There are state parks under the administration of the government of each U.S. state, and of some states of Mexico. The term is also used in Australia, though the distinction between state and national parks there is different. The Canadian equivalent term is provincial park. Similar systems of local government maintained parks exist in other countries, but the terminology varies.
State parks are thus similar to national parks, but under state rather than federal administration. Similarly, local government entities below state level may maintain parks, e.g., regional parks or county parks. In general, state parks are smaller than national parks, with a few exceptions such as the Adirondack Park in New York and Anza-Borrego Desert State Park in California.
