One of my favorite flights to do in SAN terminal area. I've done it many times, and as an instructor out of SEE, many of my students have requested to be taught it. Basically, request a shoreline south transition from Lindberg Tower before Crystal Pier, they will clear you at or below 500 and to report Ocean Beach Pier. Once you report that, they kick you off, and you need to contact Island Tower and request the Bay Tour. They will typically ask you to report the south end of Point Loma. At this point you will be cleared for the tour, at 800 ft, and to remain clear of any Naval vessels or piers... essentially stay over the water and you're gtg as long as there is no military ship in the bay, if so, deviate as necessary. It is seriously the coolest flight I have ever done, and you'll have a great time. Granted if Island Tower is closed, it's Class G below 700' and have fun.
