Riverside Island is a climbing area on city land in California, about 15 miles from Bishop. It sits among a cluster of climbing spots, with High Tension Towers and Pub Wall each about 0.1 mile away, so it works well as a base for exploring the surrounding crags. The area has 17 routes, mostly sport climbing with one trad route. The grades run from 5.10a up to 5.13b, with the median around 5.11a/b. Ratso is the trad route at 5.10a, and Conquistadors Without Swords is the hardest at 5.13b. Spring and fall are the most comfortable times to climb. Typical averages from a nearby weather station in Bishop show April highs around 74°F and October highs around 78°F, while July averages near 100°F. That station sits about 1,150 feet lower than the area, so temperatures here run cooler. Lower Rock Creek Trail, Section 3, is about 2 miles away, and Lower Rock Creek offers canoeing about 2.6 miles off. Sand Canyon, a mountain biking area, is about 4 miles away, and Tuff Campground is about 6 miles away.
