Alt Text Topographic map of the North and South Rims of Grand Canyon National Park in Arizona. Terrain is rendered in shades of reddish-brown that get darker as the canyon deepens. Two detail maps, a table, and a legend are framed in inset boxes. Extended Description This description will begin at the top right of the map with the North Rim to describe the trails, features, and amenities there before moving diagonally southwest to reach the South Rim in the lower left corner. Then the inset maps, table, and legend will be fully transcribed. North Rim Text under the label for the North Rim reads, “Full services May 15 to October 15; located 1.7 miles (2.7 km) from trailhead.” The uppermost tip of the North Rim is flanked to the west by the Kaibab Plateau and to the east by Bright Angel Canyon. The North Kaibab Trailhead, at 8,241 feet (2,510 meters), has restrooms and seasonally-available drinking water. The North Kaibab Trail then angles first southeast for about a quarter of the trail’s length before turning southwest and continuing. Just south of the North Kaibab Trailhead, the Bridle Path and Transept Trail together make a loop near or around the Station 3 Building, which has an emergency phone; the Administration and Backcountry Office; a General Store; campground; North Rim Visitor Center; and Grand Canyon Lodge. The first quarter of the North Kaibab Trail runs alongside Roaring Springs Canyon. Sites on that segment include Coconino Overlook; Supai Tunnel, which has restrooms and drinking water (seasonally); Redwall Bridge; Roaring Springs Day Use Area, which has restrooms and drinking water (seasonally); and the Manzanita Rest Area, which has a ranger station and drinking water, both seasonal, along with an emergency telephone and restrooms. Between the North and South Rims South of the Manzanita Rest Area the trail angles southwest and continues, tucked in Bright Angel Canyon. Named sites and amenities are scarce on this leg. Near the turning point, Cottonwood has campgrounds, an emergency phone, restrooms, and drinking water (seasonally). Ribbons Falls Junction is next, followed in intervals by four bridges, the fourth of which falls near Phantom Canyon and an area called The Box. The Clear Creek Trail extends eastward from The Box. Near the bottom of this section are Phantom Ranch and Canteen, a ranger station, and Bright Angel, which has campgrounds. The Colorado River cuts across this section near a note in red text reading, “Do not swim in the Colorado River! You could drown due to dangerous currents and extremely cold temperatures.” The South Rim The final quarter of this map ends at the South Rim. Just north of the Colorado River, the North Kaibab Trail splits into the South Kaibab Trail, which runs mostly south, and the River Trail, which jogs west before meandering southward. Both cross the Tonto Platform as they move south in a roughly upside-down V shape. The first, the South Kaibab Trail, passes The Tipoff, which has restrooms and telephones, Skeleton Point, Cedar Ridge with restrooms, and Ooh Aah Point before ending at the South Kaibab Trailhead, which has an emergency phone, restrooms, and drinking water. Text below the callout box reads, “South Kaibab Trailhead closed to private vehicles. Access only via free shuttle bus.” The second trail, the River Trail, curves west to the River Resthouse, which has an emergency phone and restrooms. The trail turns southwest and becomes the Bright Angel Trail, which zigzags to Havasupai Gardens with a ranger station, first aid, an emergency phone, restrooms, drinking water, and campgrounds. The final leg ends at Bright Angel Trailhead, which has drinking water and restrooms. Three locations are marked moving north from the trailhead: Lower Tunnel, 1-½ Mile Resthouse, and 3-Mile Resthouse. Just north of Havasupai Gardens, the Tonto Trail connects Bright Angel Trail and South Kaibab Trail at the approximate vertical halfway point between the canyon rim and the Colorado River. Also north of Havasupai Gardens, the Plateau Point Trail branches off from Bright Angel Trail and stretches northeast to Plateau Point, which has drinking water (seasonal). Finally, the Rim Trail traces the ledge where the Coconino Plateau meets the canyon from the left edge of the map, through the Bright Angel Trailhead, and to the South Kaibab Trailhead. Inset Map of Upper Bright Angel Trail An inset area map near the lower left corner of the larger map shows a closer view of the Upper Bright Angel Trail. Here, the Bright Angel Trail zigzags dramatically north of the trailhead at the bottom of the map. The Lower Tunnel is again labeled and now the 1 ½-Mile Resthouse and 3-Mile Resthouse have symbols for an emergency phone, restrooms, and drinking water (seasonally). The trail extends off the top right corner of this map near text reading “To Havasupai Gardens, Plateau Point, and Phantom Ranch.” Sites are also marked along the Rim Trail, which encloses this portion of the park in a curved L shape. Trailview Overlook is to the northwest and Kolb Studio, Bright Angel Lodge, El Tovar Hotel, and Verkamps Visitor Center are along the southern edge of the rim. A scale in this detail map measures 200 meters and 1,000 feet. Inset Map of Phantom Ranch An inset area map near the bottom right corner of the larger map shows how the North Kaibab Trail curves like a C down from the top center near a note reading “To Cottonwood Campground and North Rim.” The trail continues curving nearly to the right edge before veering southeast and off the map. From north to south, sites marked along the way include Hiker Dormitories, which have restrooms; Canteen with food services, restrooms, drinking water, an emergency phone, and a note reading “Snack bar open daily; dinner reservations required”; Afternoon amphitheater; Evening amphitheater; a Ranger Station with an emergency phone and first aid; Xanterra Corral; and Bright Angel Campground with campgrounds, restrooms, and drinking water. Here, about halfway down the curve of the C, a bridge crosses Bright Angel Creek to lead to the Bright Angel Campground. Another bridge connects the campground trail to the North Kaibab Trail south of this, near locations with restrooms, drinking water, and an emergency phone. The North Kaibab Trail continues to curve up past sites with drinking water and an emergency phone before it reaches a boat beach (on a separate side trail) and the Black Bridge, which crosses the Colorado River. Now named the South Kaibab Trail, it then passes through a tunnel before it continues down to the South Kaibab Trailhead. Near the second campground bridge, another trail veers southward to cross the Colorado River at the Silver Bridge, which connects to the River Trail. Continuing south on the River Trail here, near the lower left corner of the map, would lead to Indian Garden and Bright Angel Trailhead. The River Trail runs south of and roughly parallel to the Colorado River to meet the South Kaibab Trail south of Black Bridge. A scale in this detail map measures 100 meters and 500 feet. Legend The legend for the main map is in the lower right corner. Symbols for the following are listed in two columns: White cup outline against black for Drinking Water: Year-Round with the note, Always carry backup water purification, White cup outline against gray for Drinking Water: Seasonal; check availability, White ranger station against black indicates year-round availability, and White ranger station against gray indicates seasonal availability. Other symbols represent Emergency phone, First aid, Food service, Toilet, and Campgrounds with the note “Camp in designated sites only; permit required.” Trails and roads are explained as follows: Dashed black line encased in yellow for Featured trail, Dashed black line for Other trail, and White line for Road. A scale below measures 0.5 and 1 kilometers and 0.5 and 1 miles.
