From certain vantage points on Mt Lemmon, you can see Lizard Rock, an iguana shaped rock near Windy Point. This is a nice quick hike to the top of Lizard Rock where you will be treated to fantastic views of the Tucson area; from the Rincons to Baboquivari Peak. Although no official trail exists, the area sees frequent traffic, as evident by the various use trails that wind their way to the top.
From the parking pullout get out of your vehicle and head west. While your destination is hidden from view at this point, your goal is to pick one of the use trails, or a drainage, and begin to work your way up the ridge line. Make sure to stay towards the middle of the ridge, as this is the easiest path to the top. The hike through this area is composed of loose sand and rock that can make the footing a little tricky.
After scrambling through the trees for several minutes you will come out on a rocky expanse with great views to the left, right, and behind you. Be careful as you continue to work your way along the ridge towards the summit; as the drop offs become more dramatic as you near the end. In no time at all you will reach the top, where you will be afforded great views of Tucson and the Mt Lemmon Highway.
