Four peaks out by Sagauro Lake is pretty sweet lots of nice jumps,trails and some pretty challenging terrain. I personally like the winding trails up the mountian and the view when you reach the top. Take the Beeline Hwy Exit for 4 peaks past the casino about 10-15 miles after Fountian Hills.
You overlook the east valley it's really nice riding out there man, and peaceful at the top of the mountians
