Cedar Bluff State Park is a public recreation area located 21 miles (34 km) southeast of WaKeeney and 23 miles (37 km) southwest of Ellis in Trego County, Kansas, United States.

The Bluffton Area—300 acres (120 ha) on the north shore—is the most developed and receives extensive use.

The Page Creek Area—500 acres (200 ha) on the south shore—offers primitive camping as well as 36 utility sites.

[3] West of the Page Creek Area are the juniper-lined, 100-foot-tall (30 m) limestone bluffs from which the reservoir's name was derived (junipers were often misidentified as "cedars" by early settlers).

In the historic canyon one can find carvings dating back to the mid-19th century.
