The Desert Classic Petroglyphs is a site in the South Mountain Park and Preserve in Phoenix, Arizona that we haven't visited yet. It is one of over 300 petroglyph sites within the park. For turn-by-turn directions you can enter 'Pima Canyon Trailhead' into your driving app.
Included with this post is the GPS file and map that we plan to use for our first visit. If you don't want to wait for us to get around to it feel free to try the GPS file and map for yourself. With no guarantee, of course, but they most often prove valuable for us.
