You can try Kota Wisata. I don't know how to drive there but you have to use Jagorawi expressway.
Don't ever take out your camera while you are in the car unless the window glasses can prevent people from outside to see through. Well, I don't feel good to take out my camera whenever I am in Indonesia. To my assumption, when people there see camera, they would become a bull that have just seen a red cloth :think:
