Tonto Trail

Tonto Trail is a roughly 95-mile, one-way traverse from Hance Rapids to Garnet Canyon, following the Tonto Platform above the Colorado River. It contours across the broad bench, then loops into steep side drainages. Plan roughly ten to eleven hiking days for the full line; that is a planning estimate, since there is no standard through-itinerary. Most people hike it in sections reached by descending trails from the South Rim. Choose the full traverse only if you are prepared for a remote, rough backcountry trip with a permit, a detailed water plan, and a point-to-point exit.

The open platform can look level from above, but the tread repeatedly drops into gullies and climbs out over loose rock. Some sections are narrow and eroding near steep slopes, and the trail is often faint or not cairned. Keep track of the next drainage and the route’s general direction. A short spur to Plateau Point branches away near Havasupai Gardens, so check the junction before continuing west.

From the Hance Rapids end, the Tonto reaches Cottonwood Creek and climbs back onto the bench. The route then makes an outsized circuit around Grapevine Creek: about five miles of walking around a drainage that looks only half a mile across. Small springs may be present, but they are not dependable. Farther west, the trail enters Boulder Creek’s Redwall amphitheater, crosses the more open ground around Lone Tree, then winds through Cremation Creek. That last section is especially dry and exposed; it is a long way between drainages, and the creek does not provide a practical shortcut to the river. The Tip-Off and South Kaibab junction mark the end of this eastern stretch.

Where the route meets Bright Angel Trail at Havasupai Gardens, head west on the Tonto rather than taking the rim trail. The main path passes Horn Creek, Salt Creek and Cedar Spring before reaching Monument Creek and the Hermit Trail junction. Horn Creek water is naturally contaminated and should not be treated as a drinking source. Near Salt Creek, the trail runs close to a sheer drop for a short stretch. Monument Creek is the largest drainage in this section and the only one that gives a practical way down through the inner gorge; Granite Rapids at its mouth opens a striking view upriver. Toilets and designated campsites exist at some corridor use areas, but facilities thin out quickly away from them.

Beyond Boucher Creek, the trail stays near the top of the Tapeats Formation and crosses a chain of rocky side canyons toward South Bass. It can disappear among cobbles at drainage crossings, then reappear on the opposite bench. The roughly 30-mile stretch toward South Bass is among the most committing: there is no reliable water near trail level and no rim bailout between the routes. Past South Bass, the Tonto Platform narrows and finally pinches out at Garnet Canyon. There is no food service along the traverse, so carry what you need and follow the rules for the particular camping zone.
