“A well-defined and historic trail leads you to the Colorado River at the base of the Grand Canyon.”— Nicholas Shannon
The Royal Arch Route leaves the South Bass Trail and starts west where the trail comes to the Esplanade, the junction marked with a large cairn. Stay right at this intersection and follow the South Bass Trail north across the terrace east of Mount Huethawali. The route traverses near the Supai Rim for about a mile to a steep break that allows passage to the slopes below.
Dropping below the Esplanade, the trail rounds a promontory and descends Supai ledges south toward the bed of Bass Canyon. Once established in the drainage the route follows the bottom of Bass Canyon through the Redwall. The path leaves the drainage and descends most of the Tonto Group rocks via the slopes east of and above the bed of Bass Canyon, eventually returning to the bottom of the canyon just above the West Tonto Trail junction. The West Tonto Trail is marked by large cairns. Below West Tonto Trail the South Bass Trail continues down Bass Canyon, crossing and re-crossing the drainage as it winds around various obstructions. This section can be confusing, but the trail stays as close to the bed of the canyon as the terrain allows, so any disorientation shouldn't last long.
An impassable rock fall blocks access to the river at the mouth of Bass Canyon. Watch where the trail leaves the bed of the drainage, going west a short distance to a large cairn marking a shortcut that allows passage down a rocky ravine to the river below. The ravine route can be tedious and this shortcut may be bypassed by continuing another couple minutes west until a gentler path descends to the river opposite a historic fireplace.
