Oak Grove Campground offers 15 primitive walk-in tent sites with potable water access at Cooper Lake State Park's South Sulphur Unit, located approximately 100 yards from parking.

The campground features picnic tables, campfire facilities, and pet-friendly policies, making it an affordable ($15/night) option for paddlers and anglers seeking a quieter, more secluded camping experience near the lake.

No electric or sewer hookups are available, but the proximity to Elm Creek and Cooper Lake provides direct access for fishing and water recreation.
