Wall of Glass Area is a bouldering area in Mount Rubidoux Park, a city-managed park in Riverside, California. It sits among several other climbing spots, including Circle Crack Boulders and Triangle Boulders, all within about a tenth of a mile. The area is a cluster of boulders rather than a single route, and the climbing is all on rock rather than on a wall. The routes here are rated in the V scale, with grades from V0 up to V5, and the most common are V4. The boulders also have a few named problems, such as Roll up the Window and Saran Wrap, which are both V4. Spring and fall are the most comfortable times to visit. Typical averages from a nearby weather station in Riverside show April highs around 78°F and October highs around 84°F, while July and August average in the mid-90s. For more climbing, Circle Crack Boulders and Superstar Slab are right next door. The Park path and Hunter park path are both within about 3 miles for a walk.
