The Ninkasi Boulder is a bouldering area in the Mountaintop Ranger District of San Bernardino National Forest in California, managed by the Forest Service. It sits among a cluster of climbing spots, with Activator Rock and Belly Up Boulder each about 0.1 mile away. The area has five bouldering routes, all rated between V0 and V3 on the V scale. The Middle Route is V0, No Pain, No Gain is V2, and My Green Desire is V3. The Left Side Route is V0-1. The routes are all boulders, and the hardest of them, My Green Desire, is a V3. Summer is the warmest stretch. Typical averages from the nearby Big Bear Lake weather station, about 5 miles away, show July highs around 80°F with lows near 50°F, while winter highs sit in the mid-40s. That station sits roughly 770 feet lower than the boulders, so temperatures on the rock run cooler. Tanglewood Group Camp is about 0.9 mile away, and Van Dusen Canyon Spur is about 1.6 miles off. Big Bear Lake Recreation Area is about 3.4 miles away, and Holcomb Valley Ranch is about 2.4 miles away.
