Main Cliff Band is a bouldering area in Glen Canyon Park, a city-managed park in San Francisco, California. It sits among several other climbing spots, including The Unnatural Act Cave and the Glen Canyon climbing area, both about 0.1 mile away. The area has five bouldering routes, all rated between V0 and V3 on the V scale. The easiest are Crack Face and Hand Crack at V0, and the hardest is Traverse at V3. The routes are all bouldering, so there is no rope climbing here. Late summer and early fall are the driest and mildest times to visit. Typical averages from a nearby weather station in downtown San Francisco show September highs around 70°F with lows near 56°F and only about one wet day in the month. Winter brings highs in the upper 50s and roughly 11 wet days a month. Nearby, the Steep Ravine Trail and the Sutro Tower Trail for mountain biking are each about a mile away. The Beaver Street Wall climbing area is about 1.7 miles off.
