Erratica West is a bouldering area in the Amador Ranger District of Eldorado National Forest in California, managed by the Forest Service. It sits among a cluster of climbing and hiking destinations, with Boulder Geek and Erratica Central both within half a mile. The area is a bouldering spot, with nine routes all rated on the V scale. The grades run from V3 to V6, with V5 as the median. Some of the named routes are Mini Hero (V3), Slippery Arete (V4), Bump & Grind (V5) and Vision Quest (V6). Summer is the most comfortable time to visit. Typical averages from a nearby weather station at South Lake Tahoe show July and August highs around 80°F with lows in the low 40s and only about two wet days a month. That station sits roughly 850 feet lower than the area, so temperatures here run cooler. The Thunder Mountain Loop hike starts just 0.2 miles away, and the Silver Lake-Horse Canyon Trail is about 0.6 miles off. Silver Lake Campground is 0.8 miles away, and Caples Creek, a paddling spot, is about 1.7 miles away.
