Black Jack Campground is a primitive, tent-only camping area within Cimarron Canyon State Park situated directly along the Cimarron River, offering excellent access for fishing and river activities.

The campground features numbered campsites with picnic tables and fire rings, vault toilets, and a day-use area, with first-come, first-served availability and no hookups or potable water.

Spacious sites like #27 and #30 provide good river access, though site #30 requires a longer walk with gear due to its back-of-campground location.
