Slab Lake is a 4.3-mile out-and-back hike in California's Ansel Adams Wilderness, within the Bass Lake Ranger District of Sierra National Forest. The trail climbs from about 9,000 feet to a high point of 9,818 feet, with an elevation gain of 833 feet, and it is rated hard. The Forest Service manages the land, and the route is natural-surfaced and open year-round. The most comfortable months for a visit are July and August, when typical averages from a nearby weather station at Tuolumne Meadows run around 70°F for highs and 36 to 38°F for lows. That station sits roughly 1,100 feet below the trail, so temperatures on the route run cooler. The trail is not accessible, and bikes are not allowed. Horses are permitted. Post Peak lies about 0.3 miles away, and Rutherford Lake is about 0.8 miles off. Bowler and Clover Meadow campgrounds are both within about 6 miles.
