Not as Breathtaking, Literally
Barry Goldwater Peak (4083), named after the Arizona born US Senator, is the high point of the White Tank Mountain Range. Most views attribute that title to the popular Radio Summit which is just 65ft shy of BG Peak. The summit isn't visited by hikers all that often. It offers views of some western peaks that Phoenix locals probably don't get to see that often.
Hike: This is an easier, less rugged approach to Barry Goldwater Peak, starting out at the Area #7 trailhead. The majority of the rocky terrain is seen in the first 1.7 mile section, and isn't all that bad. From here, the trail forks and you'll want to head left. The rest of the MQ trail is a gradual climb on fairly level terrain. After mile marker 4, you'll begin to wind up and around an unnamed peak (3032). At the next junction, hop onto the Goat Camp Trail.
About a mile down this trail, you will find a cairn on your left (east of GC trail). This marks the Jeep trail (heading west) that will lead you to the service road. It's about 1.4 miles to the summit from here. The Jeep trail has plenty of cairns to aid you should you lose your way. When the trail thins out, make your way to the service road, and head right. Simply follow the road to the top. There's a three way junction just beneath the peak - go right. At the top, you'll find a red jar containing the summit registry, placed in 1988.
For an extra 1.8 miles, start out at the true Mesquite Canyon TH on Wildlife Way. I recommend taking the Ford Canyon/Willow Canyon trails on your way back down. According to the new park maps, it's .1 miles shorter than the 2.4 mile section of the Mesquite Trail, so there's no excuse not to. Make sure to edit your triplog information accordingly.
