Forty Foot Hole is an unconfirmed, 12-foot waterfall in the Wichita Mountains Wildlife Refuge in Comanche County, Oklahoma, despite a name that suggests a 40-foot drop.
The falls
A lidar estimate on the World Waterfall Database puts the total height at about 12 feet in three drops. The falls are recorded on both Cache Creek and West Cache Creek, and are also known as Cache Creek Falls.
Getting there
The falls lie in the Wichita Mountains Wildlife Refuge, managed by the U.S. Fish and Wildlife Service. The moderate, 1.1-mile Kite Trail reaches a canyon-rim view of Forty Foot Hole from Lost Lake or the south Boulder Picnic Area, following gravel, dirt, and rock, and is open year-round. The refuge is open daily from sunrise to sunset, and entry is free; camping and Charon's Garden backcountry permits cost extra. No closure specific to the falls was posted as of September 25, 2026, though the refuge warns that weekends are very busy.
On site
The official route gives a canyon-rim view of the falls; whether visitors can reach the pool or the base of the cascade is not documented.
