Robbins Boulder is a bouldering and climbing area in San Diego, California, set within the City of San Diego Open Space on city land. It sits in a cluster of climbing spots, with The Playground Area and the California Night Area each about 0.1 mile away, so it pairs easily with time at those nearby crags. The routes here run from bouldering to sport and trad climbing, with the most common grade in the 5.11a/b range on the YDS scale. Robbins Crack, a trad route at 5.10a, is one of the oldest, first climbed by Royal Robbins, and Eric's Face is a sport route at 5.11a/b. Lie Detector, a mixed route at 5.12a/b, is the hardest of the three. Spring and fall are the most comfortable times to visit. Typical averages from a nearby weather station show highs around 73°F in April and 82°F in October, while July and August average highs near 90°F. Warren Canyon Trail is about 0.4 mile away, and the Fry/Koegel Trail is roughly 0.9 mile off. Paddlers can reach the San Diego River about 8 miles away.
