Although permits are not required for day hikes, you must have a backcountry permit for longer trips . Some of the more popular trails are listed here; more detailed information and maps can be obtained from the Backcountry Information centers. Also, rangers can help design a trip to suit your abilities.
Remember that the canyon has significant elevation changes and, in summer, extreme temperature ranges, which can pose problems for people who aren't in good shape or who have heart or respiratory problems. Carry plenty of water and energy foods.Listen to the podcast Hiking Smart on the Park's website to prepare for your trip. The majority of each year's 400 search-and-rescue incidents result from hikers underestimating the size of the canyon, hiking beyond their abilities, or not packing sufficient food and water.
Under no circumstances should you attempt a day hike from the rim to the river and back. Remember that when it's 80°F on the South Rim, it's 110°F on the canyon floor. Allow two to four days if you want to hike rim to rim (it's easier to descend from the North Rim, as it’s more than 1,000 feet higher than the South Rim). Hiking steep trails from rim to rim is a strenuous trek of at least 21 miles and should only be attempted by experienced canyon hikers.
Rim Trail. The South Rim's most popular walking path is the 12-mile (one-way) Rim Trail, which runs along the edge of the canyon from Pipe Creek Vista (the first overlook on Desert View Drive) to Hermits Rest. This walk, which is paved to Maricopa Point and for the last 1.5 miles to Hermits Rest, visits several of the South Rim's historic landmarks. Allow anywhere from 15 minutes to a full day, depending on how much of the trail you want to cover; the Rim Trail is an ideal day hike, as it varies only a few hundred feet in elevation from Mather Point (7,120 feet) to the trailhead at Hermits Rest (6,650 feet). The trail also can be accessed from several spots in Grand Canyon Village and from the major viewpoints along Hermit Road, which are serviced by shuttle buses during the busy summer months. On the Rim Trail, water is only available in the Grand Canyon Village area and at Hermits Rest. Easy. Grand Canyon National Park, Arizona, 86023.
Bright Angel Trail. This well-maintained trail is one of the most scenic hiking paths from the South Rim to the bottom of the canyon (9.6 miles each way). Rest houses are equipped with water at the 1.5- and 3-mile points from May through September, and at Indian Garden (4 miles) year-round. Water is also available at Bright Angel Campground, 9¼ miles below the trailhead. Plateau Point, on a spur trail about 1.5 miles below Indian Garden, is as far as you should attempt to go on a day hike; the round-trip will take six to nine hours.
Bright Angel Trail is the easiest of all the footpaths into the canyon, but because the climb out from the bottom is an ascent of 5,510 feet, the trip should be attempted only by those in good physical condition and should be avoided in midsummer due to extreme heat. The top of the trail can be icy in winter. Originally a bighorn sheep path and later used by the Havasupai, the trail was widened late in the 19th century for prospectors and is now used for both mule and foot traffic. Also note that mule trains have the right-of-way—and sometimes leave unpleasant surprises in your path. Moderate. Grand Canyon National Park, Arizona, 86023.
Clear Creek Trail. Make this 9-mile hike only if you are prepared for a multiday trip. The trail departs from Phantom Ranch at the bottom of the canyon and leads across the Tonto Platform to Clear Creek, where drinking water is usually available but should be treated. Moderate. Trailhead: Phantom Ranch, Grand Canyon National Park, Arizona, 86023.
Grandview Trail. Accessible from the parking area at Grandview Point, the trailhead is at 7,400 feet. The path heads steeply down into the canyon for 3 miles to the junction and campsite at East Horseshoe Mesa Trail. Classified as a wilderness trail, the route is aggressive and not as heavily traveled as some of the more well-known trails, such as Bright Angel and Hermit. There is no water available along the trail, which follows a steep descent to 4,800 feet at Horseshoe Mesa, where Hopi Indians once collected mineral paints. Hike 0.7 mile farther to Page Spring, a reliable water source year-round. Parts of this trail are icy in winter, and traction crampons are mandatory. Difficult. Trailhead: Grandview Point, Desert View Dr., Grand Canyon National Park, Arizona, 86023.
Hermit Trail. Beginning on the South Rim just west of Hermits Rest (and 7 miles west of Grand Canyon Village), this steep, unmaintained, 9.7-mile (one way) trail drops more than 5,000 feet to Hermit Creek, which usually flows year-round. It's a strenuous hike back up and is recommended for experienced long-distance hikers only; plan for six to nine hours. There's an abundance of lush growth and wildlife, including desert bighorn sheep, along this trail. The trail descends from the trailhead at 6,640 feet to the Colorado River at 2,300 feet. Day hikers should not go past Santa Maria Spring at 5,000 feet (a 5-mile round trip).
For much of the year, no water is available along the way; ask a park ranger about the availability of water at Santa Maria Spring and Hermit Creek before you set out. All water from these sources should be treated before drinking. The route leads down to the Colorado River and has inspiring views of Hermit Gorge and the Redwall and Supai formations. Six miles from the trailhead are the ruins of Hermit Camp, which the Santa Fe Railroad ran as a tourist camp from 1911 until 1930. Difficult. Trailhead: Hermits Rest, Hermits Rd., Grand Canyon National Park, Arizona, 86023.
South Kaibab Trail. This trail starts near Yaki Point, 4 miles east of Grand Canyon Village, and is accessible via the free shuttle bus. Because the route is so steep (and sometimes icy in winter)—descending from the trailhead at 7,260 feet down to 2,480 feet at the Colorado River—and has no water, many hikers take this trail down, then ascend via the less-demanding Bright Angel Trail. Allow four to six hours to reach the Colorado River on this 6.4-mile trek. At the river, the trail crosses a suspension bridge and runs on to Phantom Ranch. Along the trail there is no water and little shade. There are no campgrounds, though there are portable toilets at Cedar Ridge (6,320 feet), 1.5 miles from the trailhead. An emergency phone is available at the Tipoff, 4.6 miles down the trail (3 miles past Cedar Ridge). The trail corkscrews down through some spectacular geology. Look for (but don't remove) fossils in the limestone when taking water breaks. Even though an immense network of trails winds through the Grand Canyon, the popular corridor trails (Bright Angel and South Kaibab) are recommended for hikers new to the region. Difficult.
