Mammoth Rock is a climbing area in Franklin Mountains State Park in Texas, managed by State Park and Recreation. It sits within the park's state park land unit, and the nearest town is El Paso, about 30 miles away. The area has five alpine-style routes, all rated between 5.8 and 5.11 on the YDS scale. The easiest is Wrangels Original at 5.8, and the hardest is Local Loser at 5.11. The routes are all alpine, and the area is close to Thunderbird, another climbing area about 0.3 miles away. Spring and fall are the most comfortable times to visit. Typical averages from a nearby weather station show April highs around 75°F and October highs around 76°F, while June and July average highs near 93°F. That station sits about 1,000 feet lower than the park, so temperatures at Mammoth Rock run cooler.
