The trailhead for the South Kaibab Trail is located off of the Yaki Point Road, which is closed to private vehicles.
The trailhead can be accessed via either the Rim Trail or the free Grand Canyon National Park shuttle bus.
Hikers begin with a steep descent through the Grand Canyon's upper rock layers: the Kaibab Limestone and Toroweap Formation.
After Skeleton Point, the trail begins a sharp descent through a natural break in the Redwall Limestone.
The Tonto Trail heads west towards Havasupai Gardens, and east towards Horseshoe Mesa and Hance Rapids.
About ¼ past the junction is a point called the Tipoff, where an emergency phone is located on the east side of the trail.
After the Tipoff the trail makes its final steep descent to the bottom of the canyon, through the Tapeats Sandstone and Vishnu Schist.
One-half mile past the junction, there is a tunnel that leads to the Black Suspension Bridge crossing the Colorado River.
[4] Hikers may only camp at the Bright Angel Campground, where they can stay overnight with a permit issued by the Grand Canyon National Park Backcountry Information Center.
