Royal Arch: The Perfect Loop
Pack two days' worth of water and dive into the heart of Harvey Butchart country on this 4- or 5-day, 34-mile trip.
Hike It The author's route went straight to Royal Arch and back, but this loop packs in more canyons and cliffs, plus a 20-foot technical rock climb on day three. Starting at the South Bass trailhead (1, see below), descend 1.2 miles north to a three-way junction to begin a counterclockwise loop. Go straight on South Bass Trail (2) and drop into Bass Canyon, descending more than 2,000 feet in 2.5 miles between two towering sandstone buttes that pinch the gorge tight. Bear left onto the Tonto Trail (3) and go 1.5 miles to a plateau campsite (4) under the 4,800-foot red walls of Tyndall Dome.
Start day two by 8 a.m. to avoid the midday scorch–it's 11.5 miles to a primo campsite on the Colorado River, the trip's first dependable water source. Follow the Tonto Trail west to the bottom of Copper Canyon (5), where you might find water in potholes after a rain. The route veers around 4,700-foot Fiske Butte and traces sheer sandstone cliffs above Walthenberg Rapids, which roar through Granite Gorge. After 10 miles, the Tonto Trail ends in Garnet Canyon (6). Head west on an unmaintained trail dotted with cairns. End at the sandy banks of Toltec Beach (7), your second camp at mile 17.5. On day three, leave your pack at camp for a 2.1-mile out-and-back to Elves Chasm (8), a secluded, waterfall-rich grotto at the mouth of Royal Arch Creek. Backtrack to camp and lay over or finish the day's remaining six miles with a stiff ascent to a roughly 20-foot rock wall and the technical crux of the trip (9).
Pack a harness, 40-foot dynamic rope, locking carabiner, and 20 feet of webbing for belays and for hauling up packs. From the top of the cliff, the route climbs gradually for 1.7 miles before dropping into Royal Arch Creek (10). Then, descend the rocky creekbed to Royal Arch (11), the Grand Canyon's largest natural rock bridge (there's a reliable spring upstream of it). Hike back upstream 3.2 miles to a set of smooth potholes carved into the creekbed, and your last campsite (12). The final day ascends past Montezuma, Toltec, and Chemehuevi Points. After 7.3 miles, reconnect with the South Bass Trail and climb 1,200 feet to your starting point.
The Way To reach the South Bass trailhead, go west from Tusayan six miles on FR 328 (off of AZ 64). Veer northwest onto FR 328A for another 17.6 miles to Pasture Wash Road. Turn right and continue to the parking lot.
When to Go Spring, when water is plentiful, or fall. Summer brings heat and flash floods.
