Arena, also known as Contender Wall, is a climbing area in Colorado on county land within the Boulder Falls area of the Boulder Ranger District of the Arapaho and Roosevelt National Forests. It sits among several named climbing areas, including Catacombs and Cenotaph Spire, both of which are about 0.1 mile away. Summer is the most comfortable time to visit. Typical July highs reach about 79°F with lows near 50°F, based on averages from a nearby weather station. That station sits roughly 900 feet lower, so temperatures at the wall run cooler. Hikers can head to the Hawkins Surguine Spur Trail about a mile away. For overnight stays, Winiger Ridge campground lies about 4 miles off, and Gordon Gulch campground is just under 5 miles away.
