The mountain range earned its name from the "number of depressions or "tanks" in the white granite near the base of the mountains", according to Wikipedia. Monsoon season occurs in the warmest months and is when you can typically find these "tanks" full of water. During the remainder of the year, they are often dry.

The most common way to hike this loop is from the trailhead on Ramada Way. Drinking water and restrooms are available. Near the trailhead, you can also find an abundance of weathered saguaro and teddy bear cholla - named for the almost "furry" appearance of their needles.

The hike begins with a series of switchbacks as the trail ascends quickly to a saddle. Jagged rock and shale define much of this hike, and unprepared hikers often turn around here after soaking in some views.

After a brief descent the trail leads to the intersection with Willow Canyon Trail. Take the opportunity to relax under the shade before continuing - it's the only notable spot on the trail to.

From here, you can complete the loop in either direction. Mesquite Canyon Trail is a steady ascent as the path hugs the contours of the mountain. In contrast, Willow Canyon Trail provides two steeper climbs separated by a traverse along a groove in the canyon wall. This is the most remote, and arguably the most unique section of the hike.

Overall, these exposed desert mountains provide incredible views all along the way. At times, you may even catch a distant glimpse of Phoenix from various spots within the canyon.
