It's a cemetery, but the view from up here is stunning and you can see one of the most large scale epic paintings ever made by a human: The Crucifixion painting, by Polish artist Jan Styka. It's a must see.
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.
