The ultimate Grand Canyon experience — hiking 21-24 miles from the North Rim (8,241 ft) to the South Rim (6,860 ft) or vice versa, descending into and climbing out of one of Earth's greatest geological features. Most hikers take 2-4 days with overnight stays at Bright Angel Campground or Phantom Ranch.
The Grand Canyon Rim-to-Rim Hike is one of the most celebrated multi-day treks in North America, traversing the full depth of one of Earth's greatest geological wonders in northern Arizona. The route covers 21 to 24 miles depending on which corridor trail is selected, descending from the North Rim at 8,241 feet elevation via the North Kaibab Trail to Phantom Ranch at the canyon floor, then ascending to the South Rim at 6,860 feet via either the Bright Angel Trail or the steeper South Kaibab Trail. The combined elevation change exceeds 5,000 feet of vertical relief, passing through exposed rock formations spanning nearly two billion years of Earth's geological history — a visible record in the distinct bands of Kaibab limestone, Redwall limestone, and the ancient Vishnu schist at the inner gorge. Most hikers complete the crossing in two to four days, spending nights at Bright Angel Campground or the historic Phantom Ranch, the only lodge within the canyon interior accessible by foot or mule. Phantom Ranch cabin beds and dormitory bunks must be booked separately from backcountry permits and sell out within minutes of their release lottery. Prior day-hiking experience and solid aerobic fitness are both prerequisites; the trail is unsuitable for beginners, young children, or anyone with significant cardiovascular or joint conditions. The primary hazard is extreme heat at the inner gorge, where temperatures regularly exceed 110°F in summer, and the National Park Service actively discourages any attempt to complete the full crossing in a single day. All water must be self-carried between reliable refill stations at Cottonwood Camp, Bright Angel Creek, and Bright Angel Campground — a minimum of four liters of carrying capacity per person is recommended. Electrolyte supplements are as important as water; hyponatremia from over-hydrating without salts is a documented canyon emergency. Backcountry overnight permits cost $10 per group plus $8 per person per night and are issued by the NPS Backcountry Information Center, with applications opening on the first of each month for dates four months out. The North and South Rims are 220 road miles apart, requiring advance transport planning; Trans-Canyon Shuttle operates a seasonal service between the rims. Sturdy ankle-support hiking boots with lugged soles are essential for the loose trail surfaces at lower elevations.
Activity facts

- 2-4 days (multi-day)
Highlights
- Descend through 2 billion years of geological history into one of Earth's greatest natural wonders
- Overnight stay at Phantom Ranch, the only lodging at the canyon floor, accessible by foot or mule only
- Cross the Colorado River on a suspension bridge deep within the canyon's inner gorge
- Panoramic views from both the North Rim at 8,241 ft and the South Rim at 6,860 ft
- Spot ancient Vishnu schist formations — some of the oldest exposed rock on Earth — at the Granite Gorge
Tips for visiting
- Submit backcountry permit applications on the 1st of the month exactly 4 months before the trip start date; competition is intense and early-morning submission is essential
- Start hiking before sunrise each day — inner gorge temperatures exceed 110°F by mid-morning in summer; rest in shade during midday hours
- Carry electrolyte tablets alongside water; hyponatremia from drinking water without replacing salts is as dangerous as dehydration at the canyon
- Book Phantom Ranch dormitory or cabin beds through the separate Xanterra reservation system — they sell out in minutes and are independent of backcountry permits
- Download offline NPS maps and trail waypoints before descending — cell service is absent below both rims
Frequently asked questions
Is a permit required for the Rim-to-Rim Hike?
Backcountry overnight permits are required for all camping below the rim. Permits cost $10 per group plus $8 per person per night and must be obtained through the NPS Backcountry Information Center. Day hikers on the corridor trails do not need a permit.
Which direction is easier — North to South or South to North?
Most hikers travel North to South, front-loading the steeper descent on fresher legs. The North Kaibab Trail is longer but has a more gradual upper section through the Roaring Springs canyon. Starting from the South is also possible but requires separate transport logistics.
Is the Rim-to-Rim suitable for beginners?
The hike is rated strenuous and is not recommended for beginners without significant prior multi-day hiking experience. The extreme heat, 5,000-plus feet of elevation change, and cumulative mileage over 2-4 days require both physical preparation and careful logistical planning.
How do hikers get between the North and South Rim after completing the crossing?
The two rims are 220 road miles apart. Trans-Canyon Shuttle runs a seasonal service between the rims from May through October and requires advance reservation. Many hikers arrange a private vehicle drop or use the shuttle to return to a starting trailhead.
Can the Rim-to-Rim be completed in one day?
A small number of trained athletes complete the crossing in a single day as a personal challenge, but the NPS strongly advises against it. Emergency rescues are frequent among hikers who underestimate the combined effect of heat, distance, and elevation change.
