Rock Tunnel Area is a bouldering area in Phoenix South Mountain Park, on city land in Phoenix, Arizona. It sits among a cluster of climbing and hiking spots, with several other climbing areas and trails within a short walk. The area is a bouldering destination, with six routes listed, all of them boulders. The grades range from V0+ to V7, with Tunnel Vision at the top end. The routes include Crack Addict and Wussin' Out at V0+, and Tunnel Vision at V7. Winter and early spring are the most comfortable times to visit. Typical averages from a nearby weather station in South Phoenix show January highs around 67°F and lows near 42°F, while summer highs climb into the 100s. That station sits about 850 feet lower than the park, so temperatures at the boulders run cooler. The closest neighbors are the Young Man Trail, Hidden Valley Trail and Mormon Trail, each about 0.3 miles away. The Amphitheatre climbing area is about 0.4 miles off.
