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. From the trailhead, the trail heads north. Hikers begin with a steep descent through the Grand Canyon's upper rock layers: the Kaibab Limestone and Toroweap Formation. At about 1/2 mile one can observe an excellent example of a pustule dome. Here a small deposit of less dense more buoyant evaporite has punctured through a layer of harder limestone above. Through the first ¾ mile, the trail cuts through the eastern side of Pipe Creek Canyon until "Ooh-ahh Point", where the canyon walls turn around Yaki Point and the view of the eastern canyon opens up. The point is named after a common reaction to the view.
