On the Razor's Edge
Razorback (2,812') is a fin-shaped formation of tertiary rhyolite in the central Goldfields.
The preferred way to hike to Razorback begins and ends at the Willow Springs TH, which is at mile marker 204 on Highway 88 in Apache Junction. While there are no "official" trails to follow, there is a good network of trails that will take you most of the way to Razorback. Note that there is no signage on the trails, and there are several junctions along the way where trails fork. As a result, it is recommended that hikers bring along some combination of GPS tracks, topographic maps, and/or a compass.
A portion of the hike will be off-trail, although the vegetation is relatively sparse and you generally have good visibility as to where you want to go. A good idea is to go to the Eastern Camouflage Tanks which are a short distance south of Razorback. From the tanks, head north for a short distance to Razorback.
The easiest way to get on top of Razorback is from the west side of the formation. This GPS track from hikerdw shows a good route to take up to the summit of Razorback. While Razorback looks intimidating to climb, this route is actually quite easy for experienced hikers. Check triplogs for routes that other hikes may have taken.
The 360 degree views atop Razorback are awesome -- Four Peaks, Saguaro Lake, Weaver's Needle, The Flatiron, Golden Dome, Dome Mountain, and Panorama Peak are just a few of the landmarks that are readily seen. It is also a lot fun to transverse the spine of Razorback, which runs for a couple of hundred feet.
The spine of razorback is probably no more than about 5 feet wide, and it is more narrow than that in places. In many places there are vertical dropoffs on both sides of the spine that descend a substantial distance. Those that have a few of heights may not want to walk around much atop Razorback.
