Malibu's Point Dume Beach has got to be my favorite all time beach. Its a great place to get away from the city and leave your troubles behind. The beach mostly is a private, but you will definitely find beautiful seals and surfers.
You have to cross this bridge when you're driving to downtown from East LA. It gives you an amazing view on the River, old industrial buildings and the high rises of downtown Los Angeles. Remember that famous scene from Grease? This is the place. I'm still trying to figure out how to get my car in here.
