All sites can be reserved online at San Gorgonio. If no reservation has been made for a particular night in a certain site #, you may select it for "one night only" on a walk-in basis. Anyone who might reserve it online the next night would have rights to the spot. South Fork campground up the road, is walk-in only.
You will have to reserve online and select a specific site. It will easier to reserve during the week or a non holiday. If you are looking for a holiday weekend (Memorial day or Easter) book at least 3 months in advance.
