Depending on the time of year you will be going, the commercial flower fields in Carlsbad may be blooming. A beautiful sight and you can tour them. Point Loma has tide pools. IF you have time, stay off the freeway and instead go through the little coastal towns that dot the Pacific. Coronado Island and La Jolla are both suburbs of San Diego and are very scenic. If you go to Coronado, take the bridge. In Coronado, visit the Hotel del Coronado, a historic landmark. Laguna Beach and Newport Beach are both very popular. Lots to do and see. In Newport, there is a (very) small ferry that takes you to the Fun Zone. Huntington Beach is Surf City USA. There is also the Bolsa Chica Ecological Reserve. Balboa Island, very close to Newport, is very cute with shops and restaurants. You get there via a bridge. Get a frozen chocolate--covered banana! San Juan Capistrano is on the way. There is a Mission there and (supposedly) where the swallows come back every year on St. Joseph's Day (March 19). There is an old song, "When the Swallows Come Back to Capistrano." I happen to live in Manhattan Beach, one of the three beach cities that comprise the South Bay (the other two are Redondo Beach and Hermosa Beach), so I am very partial to it. The Manhattan Beach Pier has a small, free aquarium at the end. Tons of surfers. A great casual restaurant is The Kettle, two blocks up from the pier. Venice Beach is north of LAX but, sad to say, has become overridden by the homeless. This is where Muscle Beach is located. Due to Covid issues, if you plan to visit any of these areas/places, I would check to be sure what you want to see is open. Things are changing daily. Have fun!
