San Luis Creek Group Campground offers two reservation-only group camping areas on O'Neill Forebay's shoreline: Group Camp A accommodates up to 60 people and 15 vehicles, while Group Camp B accommodates 30 people and 10 vehicles, both featuring shade ramadas, tables, fire rings, flush toilets, and hot showers.

The campground provides access to a 5-mile accessible walking trail along the forebay shoreline, a nearby boat launch, and North Beach day-use area, though the open terrain experiences significant wind exposure typical of the western San Joaquin Valley.

All boats must be removed from the water by sunset.
