Our family went recently to the Baldwin Hills Scenic Overlook, on Jefferson at Hetzler. You can take the hiking trails, but most people come for the stairs. There are 300 of them, and they go straight up the side of this hill. The hill starts feeling like a mountain half-way up. After you reach the top, you are rewarded with an amazing view of the L.A. area that reaches from Downtown all the way out to the Pacific. Gorgeous! The view is so beautiful, that people take wedding photos up there.
The only downside to this place is that you have to park on the street, unless you want to pay to park at the top of the hill and go down first. On the busy day when we visited, we had to park about 4 blocks away.
