Williamson stands in the John Muir Wilderness of the Inyo National Forest. It is located approximately 6 miles (10 km) north of Mount Whitney, the highest peak in the contiguous U.S., and about 2.5 miles (4 km) southeast of Shepherd Pass, the nearest trail access. The closest town is Independence, California, about 12 miles (19 km) to the north-north-east. It lies about 1 mile (1.6 km) east of the Sierra Crest, which forms the western edge of the Owens Valley. It is more remote than Whitney in terms of access; however, as it sits east of the crest, it is actually a bit closer to the Owens Valley floor than Whitney. For example, the drop from the summit to the forest edge is 8,000 feet (2,400 m) in approximately 4 miles (6.4 km). This makes it an imposing mountain, and far less of a popular climb than its higher neighbor.
The mountain is named for Lt. Robert Stockton Williamson (1825–1882), who conducted one of the Pacific Railroad Surveys in Southern California.
The first recorded ascent of Mount Williamson was made in 1884 by W. L. Hunter and C. Mulholland, by way of the Southeast Slopes Route. The first ascent of the West Side Route was made in 1896 by Bolton C. Brown and Lucy Brown. New routes continued to be put up on the harder faces at least through the 1980s.
The standard ascent route is the West Side Route, accessed from Shepherd's Pass. From the pass, one travels across the Williamson Bowl, which lies between Mount Williamson and Mount Tyndall, part of the Sierra Crest. The bowl is home to five high alpine lakes. From the bowl, the route climbs gullies up the west face to the relatively broad summit plateau; this portion involves scrambling up to class 3. Technically easier, but with a more difficult approach which can involve route finding and bushwhacking, is the Southeast Slopes Route, rising from George Creek. Other routes exist on the mountain, including a significant technical route on the North Rib (Grade IV, 5.7).
Climbing Mount Williamson is made more difficult by the lengthy and strenuous approach. Elevation gain from the trailhead is over 8,000 feet (2,400 m), and the trail to Shepherd's Pass alone is 11 miles (18 km).
Mount Williamson is in the California Bighorn Sheep Zoological Area and these rare animals can often be seen on the lower slopes during the winter when heavy snows drive the sheep down from their summer grazing areas. From 1981 until 2010 the California Bighorn Sheep Zoological Area was closed to access for much of the year, but late in 2010, the Inyo National Forest Service declined to renew the closure, opening the area to access year-round.
