Hualapai River Runners is the local outfitter for motorized Colorado River rafting trips that begin from Peach Springs. Trips use Diamond Creek Road to reach the river, then run a remote section of the Grand Canyon with Hualapai guides, rapids, canyon walls, and a very different sense of scale from the rim viewpoints.
Book well ahead and read the trip conditions carefully. This is not a casual float, and the logistics are part of the adventure: early starts, rough-road transfers, heat, water, and tribal-land access rules all matter.
