Grand Canyon

Overview

The Grand Canyon is a vast gorge cut by the Colorado River through the Colorado Plateau in northern Arizona, exposing a sequence of rock layers that reads like a cross-section of the continent's early history. Its scale is difficult to absorb even when standing right at the rim: cliffs, terraces and buttes fall away in bands of red, orange and cream rock towards a river that is often invisible from above, hidden in the inner gorge.

The canyon is split into the South Rim and North Rim, separated by a river corridor that takes days to cross on foot or by raft but only a short flight by air. Most visitors go to the South Rim, which stays open year-round and has the greater range of services, viewpoints and transport options, while the North Rim is quieter, higher, cooler and closed for much of the year.

This is a landscape best understood slowly, whether that means a short walk along the rim trail, a mule ride below the edge, or multiple days hiking down to the river and back. The surrounding land includes national forest, tribal reservations and a national monument, all of which shape how the canyon is approached, managed and experienced.

Key facts

Overview and character

The canyon was carved by the Colorado River as the Colorado Plateau was slowly uplifted, a process that exposed rock layers spanning roughly two billion years of geological history. Geologists still debate exactly how and when the canyon reached its present form, with different segments appearing to have formed at very different times before eventually joining into one continuous waterway. The result is a place valued as much for its scientific significance as for its visual drama, with rock strata that geology students and researchers travel specifically to study.

For thousands of years the canyon and its side canyons were inhabited by Native American peoples, some of whom built dwellings directly into the canyon walls and caves. The Pueblo people regarded the canyon as sacred ground and made pilgrimages into it, and several tribes, including the Havasupai and Hualapai, maintain reservation land within or alongside the canyon today. The first European to see it was a Spanish soldier travelling with an expedition in the sixteenth century, though the canyon remained largely outside non-Native awareness for centuries afterwards.

Things to do

Rim walking is the simplest and most rewarding activity for casual visitors: paved and mostly flat trails run along sections of the South Rim, linking viewpoints such as Mather Point, Yavapai Point and Hopi Point, each offering a distinct angle on the canyon's folds and side gorges. Hiking below the rim is a different proposition entirely, with trails like Bright Angel and South Kaibab dropping steeply through the rock layers towards the Colorado River; even a short descent gives a much better sense of the canyon's true depth than any rim view can.

Mule rides down into the canyon, some ending overnight at Phantom Ranch by the river, have been offered for generations and remain popular, though they require booking well ahead. Rafting trips through the inner gorge, ranging from short sections to full traverses of the canyon, offer a completely different perspective from the water itself, passing beneath cliffs that are impossible to appreciate from above. For a wider aerial view, small aircraft and helicopter tours operate from nearby airports, while stargazing has become a draw in its own right thanks to the canyon's dark, unpolluted night skies.

Areas to explore

Grand Canyon Village on the South Rim is the main hub, with historic lodges, the rim trail, visitor centres and the start of the main hiking routes into the canyon; it feels less like a town and more like a purpose-built base for exploring the rim. Desert View, further east along the South Rim, is quieter and centres on a stone watchtower with panoramic views, marking the point where the road enters from the eastern side near the Navajo Nation.

The North Rim, reached by a separate and much longer road, has a single lodge and a handful of viewpoints such as Bright Angel Point, and its higher elevation gives it cooler air and thicker forest cover than the south side. Havasu Canyon, on Havasupai land to the west, is a separate side canyon known for its turquoise waterfalls, reached only by a long hike, helicopter or mule ride and requiring a permit arranged directly with the tribe. The western end of the canyon, on Hualapai land, includes the Skywalk, a glass viewing platform extending out over the rim, which operates independently from the national park.

When to visit

Spring and autumn are generally the most comfortable times to visit the South Rim, with milder temperatures than the intense heat of summer, which can make inner-canyon hiking dangerous during the middle of the day. Summer brings frequent afternoon thunderstorms to both rims, dramatic to watch from a viewpoint but a serious hazard for anyone hiking below the rim without shade or water. Winter transforms the South Rim into a quieter, sometimes snow-dusted landscape and remains open, though services are reduced, while the North Rim's access road closes for winter and the facilities there shut down entirely. The North Rim's short operating season means anyone planning to visit that side needs to check opening dates carefully before travelling.

Getting there

The nearest sizeable airports are in Phoenix and Las Vegas, both a long drive from the canyon, while a smaller regional airport near the South Rim handles limited scenic and charter flights. Most visitors arrive by car via Flagstaff, Williams or the Navajo Nation to the east, all of which connect to the South Rim entrance roads. A historic railway also runs between Williams and Grand Canyon Village, offering a slower, car-free alternative that terminates close to the rim itself. Reaching the North Rim requires a separate, considerably longer drive around the canyon's eastern end, as there is no direct road link across the gorge for ordinary vehicles.

Getting around

Within Grand Canyon Village and along the South Rim, a free shuttle bus system connects the main viewpoints, trailheads and visitor facilities, and using it is far less stressful than trying to park at every stop along the rim road. Some sections of the rim drive are closed to private cars for parts of the year, making the shuttle the only practical option at busier viewpoints. Hiking remains the only way to get below the rim independently, while mule trips offer an alternative for those wanting to descend without walking. Between the two rims, options are limited to the long road journey, chartered small aircraft, or a multi-day hike across the canyon floor, so travel between them needs planning well in advance.

Day trips

Havasu Canyon's waterfalls make a memorable, if logistically demanding, side trip, requiring a permit and either a long hike or a helicopter transfer from the reservation's own heliport. The Hualapai-run Skywalk and Grand Canyon West, near the canyon's western end, can be visited as a long day trip from Las Vegas, offering a very different experience from the main park with less emphasis on hiking and more on quick viewing. Flagstaff, a college town with its own historic centre and access to the San Francisco Peaks, makes a pleasant base for those wanting a broader trip beyond the canyon itself. Williams, along the old Route 66 corridor, offers a smaller-scale, more relaxed stopover point and is the departure town for the heritage railway into the park.

Where to stay

Lodges within Grand Canyon Village on the South Rim, some dating back over a century, offer the advantage of waking up within walking distance of the rim, though rooms need to be booked far ahead, especially in summer. Tusayan, just outside the park's south entrance, has a wider spread of hotels and is a practical fallback when in-park lodges are full. The North Rim has a single historic lodge with cabins, memorable for its setting but limited by the short season it operates each year. Flagstaff and Williams offer a much larger choice of accommodation at generally lower cost, at the expense of an extra drive to reach the canyon each day.

Good to know

Altitude and dryness catch many visitors out: both rims sit at considerable elevation, and the dry air combined with intense sun means dehydration is a real risk on any hike below the rim, however short it looks on a map. Mobile signal is patchy across much of the park, and inner-canyon trails have limited water sources that are sometimes turned off seasonally, so carrying enough water is essential. Wildlife including elk and California condors can be seen around the rim, and both should be given plenty of space. Entry is by a multi-day pass covering the whole park, and rangers strongly discourage attempting to hike from rim to river and back in a single day given the heat and elevation change involved.

Common questions

Can you see the Colorado River from the South Rim?

In most places the river is hidden by the inner gorge's walls and cannot be seen from the main rim viewpoints; a few specific overlooks and a hike partway down are needed to glimpse it.

Is it possible to visit both the North Rim and South Rim in one trip?

Yes, but it requires a long drive around the canyon's eastern end since there is no direct road across it, and the North Rim is only open for part of the year, so timing needs checking in advance.

Do you need a permit to hike to the bottom and back in a day?

No permit is needed for day hiking, but rangers advise against attempting the full descent and return in one day because of heat, elevation change and limited water; overnight trips below the rim do require a backcountry permit.

How do you get to Havasu Falls?

Havasu Falls sits on Havasupai tribal land within a side canyon and is reached by a long hike, mule transport or helicopter from the reservation's village, with a permit booked directly through the tribe rather than the national park.
