Greenleaf State Park, State park in Oklahoma, US.

Greenleaf State Park surrounds 930-acre Greenleaf Lake near Braggs, Oklahoma. The lake was built in 1939, and an 18-mile hiking trail starts inside the park, loops around the water and continues into the adjacent Camp Gruber land. Cabins, campgrounds and recreation facilities sit around the lake, and a wooden boat dock with plank decking and simple railings stands in the water.

Greenleaf State Park was developed in the 1930s by the CCC, WPA and German prisoners of war, who built the original structures from native stone. The park initially had 14 one-bedroom cabins of about 350 square feet, some with fireplaces. In 1994, Cabin 15, the "Cabin on the Lake," was added as a fully accessible cabin donated by Telephone Pioneers of America.

Greenleaf Lake was built in 1939, and the park's naturalist leads campfire programs, astronomy nights, storytelling sessions and hay wagon rides. Party barges tour the lake, and children 16 and under fish free at the kids' pond without a permit. Jet skis and wave runners are not allowed on the water.

The park offers furnished cabins with full kitchens, RV sites with electrical hookups, and tent camping areas, all requiring advance online reservations. Visitors should decide their preferred accommodation type ahead of time, as amenities vary between lodging options.

The park maintains a dedicated kids fishing pond where children under 16 can fish without needing a permit. An accessible cabin by the water features its own private boat dock for easy lake access.
