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.
This is a great place to walk around. It really feels like a mini Lake Shasta or something tucked right up in the Hollywood Hills. Ornate statues on the bridge and sweet smelling trees. If you squint you almost feel like you're not in the middle of a massive city.
