San Luis Creek Campground offers 42-53 sites with water and electric hookups on O'Neill Forebay, accommodating RVs up to 30 feet, with a boat ramp for water access and a 5-mile accessible walking trail along the shoreline.

The campground features fire rings, tables, and a dump station, though it has minimal shade and is exposed to wind; reservations are recommended and can be made through ReserveCalifornia.

All boats must be removed from the water by sunset, and boaters should be aware of shallow areas and counterclockwise traffic patterns on the forebay.
