Black Mesa State Park

Oklahoma (Cimarron County)

Black Mesa State Park sits in the far western tip of Oklahoma’s panhandle in Cimarron County, where the landscape feels more like New Mexico than the Great Plains. Established in 1959, this 349-acre park serves as the base camp for reaching Black Mesa itself — the highest point in Oklahoma at 4,973 feet above sea level. The mesa’s flat-topped summit, capped by ancient lava rock, offers sweeping views across three states: Oklahoma, Colorado, and New Mexico.

The signature experience here is the 8.6-mile round-trip trail to the summit, marked by a granite monument at the top. The hike crosses open rangeland dotted with juniper and pinyon pine, with dinosaur trackways visible in the rock along the way. Beyond the mesa trail, the park offers fishing and boating on Carl Etling Lake, a modest but productive spot for channel catfish and bass. Birders come for species rarely seen elsewhere in Oklahoma, including roadrunners, golden eagles, and lesser prairie-chickens.

The park’s remote location in the least-populated county in Oklahoma means genuinely dark skies — excellent for stargazing without the usual light pollution. Spring and fall bring the most comfortable hiking temperatures, as summer days regularly push past 100 degrees and winter winds across the open mesa can be brutal.

With its volcanic geology, dinosaur fossils, and high-desert terrain, Black Mesa feels like a detour into the American Southwest — all within Oklahoma’s borders.
