This is the toughest mountain in Phoenix area. Try this only if you are in moderately good shape and also bring tons of water. Its more like Rock climbing than hiking.
Its better to reach before 5:30 AM. If you reach after 5:30 AM, getting a parking space is difficult and it gets very hot when coming back.
They have rails in multiple places to help and the best part is the view on the top of the mountain.
Tough one..But its worth !
