Half Moon Boulder - South is a bouldering area in Mount Rubidoux Park, a city-managed park in California. It sits among several other climbing areas, including the Half Moon Area, Turtle Dome and Cross Rock Area, all within about a tenth of a mile. The climbing here is all bouldering, with five routes in total. Two of them are named: Fly Ash, rated V1+, and Clinker, rated V2. The grades are on the V scale, and the routes are short, so they work well for a quick session on the rock. 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 82°F, while July and August average in the low 90s. For a walk, the Park path is about 2.5 miles away, and the Gage Canal Path is about 3.8 miles away. Paddlers can find Lytle Creek roughly 9 miles off.
