The Lost Sierra is a climbing area in California's Plumas National Forest, within the Beckwourth Ranger District. The Forest Service manages the land, and the area sits among a cluster of hiking routes, camping spots and paddling waters. For a climbing outing, the area offers two routes, one boulder and one mixed. The mixed route "Wipe twice" is rated about 5.7+ on the YDS scale and V3 on the V scale. Summer is the warmest stretch. Typical averages from a nearby weather station run from highs around 73°F in June to about 82°F in July, while winter highs sit in the mid-40s and lows near freezing. That station sits roughly 1,400 feet lower than the climbing area, so temperatures up high run cooler. The closest outings are the Grizzly Ridge and Buckhorn Trail hikes, both within about 3 miles. Long Valley Creek offers paddling about 4 miles away, and Bradys Camp (Family Campground) is about 4 miles out.
