If you find yourself in Malibu for any reason, stop by the Pepperdine university campus and check out this grass field. If there aren't any lacrosse practices happening, then you can sit and fell like you're on the edge of the world.
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.
