Here's a great alternative to the crowded summit trail with many rewards. You can access this trail from all the inner trailheads. The easiest and least crowded being the Hopi Trailhead. That's the first left after the Ranger Station. The trail takes off in either direction behind the ramada. Heading clockwise you will encounter the summit trailhead in a quick 0.4 miles. Next you will take the summit trail for a half mile. At the 0.6 mile marker on the summit trail take a left onto the circumference route. This is the only left hand turn you take.
From here on take all the right hand turns. Which makes perfect sense because you will be circling the mountain. From the 0.6 saddle the trail drops off immediately. Zig zagging down the slope here gives you a feeling that you have arrived. I say that because I always feel like I've just completed a long journey and the homes below are the destination. Yeah, I know that's a little far fetched.
During a good wet season Brittlebush blooms cover this slope in a sea of yellow. The first junction is encountered after the zig zagging, continue right (North). The trail roller coasters to the low lying northwest saddle. Before the saddle is one nice area I call the three saguaros, two switchbacks and one beautiful skyline. Soon after you'll reach the northwest saddle.
The Perl Charles 1A Trail joins at the saddle from the northwest. From the saddle go down and east. A few steps past the saddle and the noise of the city takes a sudden decibel drop. You are now entering the area I call the desert Andes. This valley is awesome. The slopes of the facing mountains are STEEP! Continue along the roller coaster, now going up over and up.
Midway along the north stretch you might find Mexican goldpoppies on north facing slopes. Near the northeast saddle you'll enter a gully scattered thick with Saguaros. Resurrection plant covers some of the northern facing slopes. The final saddle is near. Recent trail improvements have filled the rutted sections making the going easier.
From the saddle it is all down hill. Well for most of the remaining trail any way. The trail goes down fast and is steep in sections. The valley you just entered is totally silent. It's hard to believe you're in the middle of a major city. Continue taking the right handed turns and you will eventually be paralleling the parking area below. Continue along the trail back to your starting point.
Note: Dogs are not allowed on the Summit Trail
