Where are the Best National Parks in Perth?

I think I would have to say Kings Park which is overlooking the City - it has a lot of offer and all different things you can do.
Otherwise there are some in the Hill but I cannot remember the name, and also Yanchep National park is nice.

Yanchep National Park has lots to do - hiking, caves, Aboriginal culture, kangaroos, picnic, canoeing.
