Boulder Geek is a bouldering area in California's Eldorado National Forest, within the Amador Ranger District. The Forest Service manages the surrounding land, and the climbing sits close to the Erratica Central bouldering area, about 0.1 mile away, with Erratica West about 0.3 mile off. The area has five bouldering routes, all graded on the V scale. The easiest is Pencil Necked Geek at V3, and the hardest is Boing Dexterity at V7-. The other routes run from V4 through V6-. The warmest stretch runs from June through September, when typical averages from a nearby weather station at South Lake Tahoe show highs around 80°F in July and August and lows in the mid-30s to low 40s. That station sits about 870 feet below the boulders, so temperatures here run a little cooler. Nearby options include the Thunder Mountain Loop hike, about half a mile away, and Castle Point Trail at 0.8 mile. For an overnight stay, Silver Lake Campground is about 1.1 miles away, and Caples Creek, a paddling spot, is about 1.5 miles off.
