Hiking Quartz Peak
From the parking area head northeast up the trail. You’ll pass an information stand and trail register where you can sign in and out. Follow the flat trail marked by cow pies and cairns for about a quarter mile, then it will turn left towards the base of the ridge on your left.
At 0.6 mile you’ll reach the top of the first ridge, and at 1.0 mile the second ridge. As the trail climbs it alternates between following the crest of the ridge, and dropping slightly side to side, lacing from notch to notch.
At mile 1.8 the trail becomes more rugged and a little harder to follow, then hits a couple switchbacks and gains the final ridge at mile 2. From here the trail hangs on the left side of the ridge until mile 2.3 where it pops back on top.
At the 2.5 mile mark the trail diminishes, becoming more rocky and slow. You should see some cairns to guide you to the left side of the ridge, then back to the center, then to the right, then centered again where the trail becomes more prominent at mile 2.7.
The clear path does not last. Stay near the crest of the ridge for the final quarter mile to the top. When you get near the summit there are two apparent summit blocks – Quartz is on the left. Complete the final scramble and you are there!
At the top you will be greeted by the biggest chunk of white quartz you’ve ever seen and truly appreciate the name of this peak. To the north is Phoenix, to the west is Little Rainbow Valley and to the east is the Gila River Reservation.
When you are done enjoying the views, return back down the way you came.
