Rim-to-Rim-to-Rim (R2R2R)

The Rim-to-Rim-to-Rim (R2R2R) is an iconic and exceptionally challenging ultra-distance hike spanning approximately 46.6 miles across the Grand Canyon and back. Starting from the South Rim, this route descends the Bright Angel Trail, crosses the Colorado River, ascends the North Kaibab Trail to the North Rim, and reverses the entire journey to return to the starting point. The double crossing features over 13,800 feet of cumulative elevation gain and loss, testing physical endurance, mental fortitude, and thermal management. Beginning at the Bright Angel Trailhead on the South Rim, the trail descends steeply through massive limestone and sandstone cliffs, utilizing a series of tight switchbacks in the upper four miles. Key checkpoints along this descent include the Mile-and-a-Half and Three-Mile Resthouses. The trail then levels out across the Tonto Platform to reach Havasupai Gardens (formerly Indian Garden), a lush oasis shaded by cottonwood trees. Past Havasupai Gardens, the trail descends further through a winding creek bed before negotiating the Devil's Corkscrew, a steep, rocky series of switchbacks known for extreme, trapped heat during summer months. From the base of the corkscrew, the trail traverses exposed sand dunes along the Colorado River, crossing the Silver Bridge to reach the Bright Angel Campground and Phantom Ranch area. From Phantom Ranch, the route transitions to the North Kaibab Trail, following the flowing waters of Bright Angel Creek through the towering walls of the Box. The trail climbs gradually for several miles, passing the Cottonwood Campground and providing access to side trips like Ribbon Falls and Roaring Springs. Beyond Cottonwood Campground, the ascent steepens dramatically, gaining over 3,000 feet in the final 5.4 miles to the North Kaibab Trailhead. The North Rim terminus sits at an elevation of 8,241 feet, offering a cooler, forested environment dominated by ponderosa pine and aspen. After reaching the North Rim trailhead, hikers reverse the route to complete the return leg. This involves descending back through the steep upper reaches of the North Kaibab Trail, crossing the Colorado River once more, and embarking on the grueling 4,380-foot climb back up the Bright Angel Trail to the South Rim. Success on this route requires meticulous planning regarding seasonal water availability, caloric intake, and timing to avoid the extreme midday heat of the inner canyon.

The Grand Canyon is the oldest geological wonder of the world. Looking down on it from the rim is not fully understanding it's amazing beauty - you have to venture below the rim for the full experience.
