Red Diamond Wall

Red Diamond Wall is a climbing area in Arizona's Coronado National Forest, within the Santa Catalina Ranger District. The Forest Service manages the land, and the area sits in a cluster of climbing spots, with Sky Valley and Mojo Wall and Branching Out Crag both within a few tenths of a mile. The climbing here runs from trad routes on the lower end to sport and mixed climbs that reach about 5.12b. The 12 routes on record average in the low to mid 5.10s, with High Pro Glow at 5.9- and Facets of the Mined at 5.12b as the extremes. Sidewinder is a sport route at 5.10d, and Ruby is a mixed climb at 5.11-. Spring and fall are the most comfortable times to visit. Typical averages from the nearby Mt Lemmon Willow Canyon weather station show highs around 71°F in May and 68°F in October, with lows near freezing in winter. That station sits about 360 feet below the wall, so expect temperatures on the rock to run a little cooler. Other climbing areas within about a quarter mile include Sixty Second Wall and Sky Valley. The Incinerator Ridge trail is close by for mountain biking, and Rose Canyon campground lies about 0.6 miles away for an overnight base.
