Riverside Campground is a primitive 11-site campground along the Middle Fork Boise River near Atlanta, Idaho, offering water, toilets, and picnic tables in a forested setting.

The remote location serves as a gateway to wilderness recreation with nearby trailheads providing access to the Sawtooth Wilderness and Queens River trails.

Access is via narrow Forest Service Road 268 (68 miles from Highway 21), which requires caution and extra driving time, making this campground best suited for backcountry-oriented campers; it operates mid-May through mid-October before snow closure.
