Onyx peak is a fun and challenging hike in a high desert region. This peak located on the Northwest corner of the Jawbone-Butterbreadt region in the South Fork region of the Kern River Valley which is at the beginning of the East side of the Southern Sierra Nevada Mountains. Though the peak overlooks the town of Onyx (NE) the best access point is actually from the East in Kelso Valley. The hike is about 5 miles round trip with an elevation gain of 2500 feet.

After parking start heading ENE toward the mountain on your left making your way for the ridge with the fewest rocks. I marked the approach in red on the following photograph.

After you cross the flat plain you basically just head North on the ridgeline, and the way is very steep as you climb up. There are ducks here and there which will assist you. At the top of this minor ridge turn right on the major ridge, and head ENE to the summit. You will get a break in the elevation gain for awhile, and then there is a brief rock hopping section where it may take awhile to locate the register. If you follow the "ducks" the register location is marked by a painted circle, and the benchmark is to the North of this area on a rock outcropping marked by a small cairn. The view is spectacular in all directions. Just a few of the landmarks visible from the summit are Lake Isabella, the Kern River Preserve, the Kern Plateau, Weldon, Onyx, Nicolls Peak, Heald Peak, the South Fork of the Kern River, Heald Peak, and the Kelso Valley.
