I love living in a city where I can easily go hiking during the day and be home by dark. Griffith is just massive and untamed, it has a wild feel about it in places. Views of LA, the ocean, and the Hollywood sign.
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.
