Rim-to-Rim: South Kaibab to North Kaibab

This is the Arizona Trail’s South-to-North Rim-to-Rim crossing: about 21 miles, one way, from South Kaibab Trailhead near Yaki Point, down to Black Bridge and Phantom Ranch, then up North Kaibab Trail to the North Rim. It is a point-to-point hike, not a loop, so arrange your return between rims before setting out. The trail drops about 4,800 feet to the Colorado River, then climbs roughly 5,760 feet to the North Rim. Allow about 16 hours of hiking time for a continuous push, with more time for breaks. That is a planning estimate: there is no standard published time for this exact crossing. An overnight at Bright Angel Campground or Cottonwood makes it a multi-day trip and requires a backcountry permit; day hiking itself does not.

The South Kaibab Trailhead is near Yaki Point, and private cars cannot drive to it. Park at the Backcountry Information Center and use the free hikers’ shuttle. The North Kaibab Trailhead has a small, limited parking area, and seasonal commercial shuttles connect the rims. The North Rim’s road and services are seasonal, with winter weather sometimes closing access early. Sort out the one-way vehicle or shuttle plan first; the two trailheads are far apart by road.

South Kaibab drops quickly on tight switchbacks, then follows a prominent ridge with open views almost the whole way. Ooh Aah Point is the first broad overlook. Cedar Ridge, with pit toilets but no water, is a useful pause before the path contours below O’Neill Butte. At Skeleton Point, about three miles down, a short spur gives the first clear view of the Colorado River and Phantom Ranch. Beyond it, the trail cuts across exposed limestone and descends to the Tonto Platform and Tip-Off, where there are pit toilets and an emergency phone, but still no water. The South Kaibab is especially scenic because it holds the ridge; the tradeoff is little shade and no water along the trail.

Below Tip-Off, the route passes through a tunnel cut into the rock and crosses the Colorado River on Black Bridge, also called the Kaibab Suspension Bridge. The South Kaibab follows part of the old Cable Trail, built in 1907 to reach the earlier cable car across the river. The present bridge dates to 1921. Across the river, Bright Angel Campground and Phantom Ranch sit in the canyon bottom. This is the route’s natural midpoint, but the river crossing is not the end of the work: the North Rim is still thousands of feet above you.

North Kaibab follows Bright Angel Creek north, crossing it six times. The older route crossed the creek 94 times. Near Roaring Springs, water gushes from the canyon wall and forms the creek. A pipeline installed between 1965 and 1970 carries water from the springs beneath the trail toward the South Rim. Farther up, the trail climbs through long half-tunnel sections blasted into Redwall Limestone, with a striking drop beside the tread. Supai Tunnel marks the upper part of the climb; beyond it, the canyon gives way to the higher, forested North Rim. The North Kaibab Trailhead sits at about 8,241 feet and has limited parking.

Between Cottonwood and Bright Angel Campground, the trail enters the Box, a narrow stretch of the Inner Gorge enclosed by dark Vishnu Schist about 1.7 billion years old. Where that rock meets the younger Tapeats Sandstone is the Great Unconformity: more than a billion years of geologic record is missing from the layers. The present North Kaibab Trail was built through the 1920s to replace the creek-hugging route. South Kaibab was built beginning in 1924 as a public alternative to the privately operated Bright Angel Trail.

The best wide views come from the South Kaibab ridge, especially around Ooh Aah Point and Skeleton Point. At Skeleton Point, include the Colorado River below the temples to show the scale of the descent. Later, the North Kaibab’s cliff-cut ledges and the close walls of the Box feel very different from the open South Rim ridge. This route suits experienced hikers prepared for a very long, steep day or a permitted overnight. The low inner canyon can become dangerously hot in warm weather; the high North Rim can hold snow and ice in winter. Pets are not allowed below the rim, except service animals assisting a person with a disability.
