Located deep in the backcountry of Kings Canyon National Park, Charybdis sits at the heart of one of the mountain range's least accessible regions. The shortest approach is 16 miles from the Sabrina Lake trailhead, and requires significant cross-country travel over rugged, exposed class 3 terrain. The shortest approach not requiring extensive cross-country travel is 23 miles long, beginning at the South Lake trailhead. Charybdis and its sister peak Scylla flank the Enchanted Gorge at its upper end, rising from the east and west sides of the gorge, respectively.
