Somethings just don't change....Costco will always be Price Club to me, and Piestewa Peak will always be Squaw Peak.
The Phoenix Mountain Preserves, which is home to Squaw Peak, is an amazing preserve smack in the middle of a metropolis. The well known Summit Trail is heavily traveled and well loved by regulars and visitors alike. It is a strenuous hike and is most challenging near the top. Stair like rocks lead you to the summit - but watch your step and be very careful as there are few handrails.
Parking is always a problem, especially on the weekend as everyone wants to get out and enjoy the outdoors. If the first two lots are full, keep going as there are more opportunities to park further north. And what is an extra few minutes of walking when your planning on hiking 2.4 miles roundtrip anyways?
Be sure to check out the other trails - like the Circumference Trail that starts at the north parking lot and circles the preserves, linking up with the Summit Trail near the end - giving you the option to continue to the peak. There are parts of this trail that are secluded and make you forget that you are in the middle of Phoenix. Dogs are allowed on almost all the trails except the Summit, so it is great fun for your pup. Just be sure to keep them safe from the cactus and bring plenty of water.
I highly recommend this hike and be safe!
