This is the hardest part of the route: steep slopes, narrow drop-offs, hands-on scrambling and more route-finding than the maintained approach. A pool on the Primitive Trail may hold water. Skip this section when the rock is wet or icy, and turn back if the exposure is already wearing you down. The side trip to Private Arch adds another rocky alcove to the day, but the return through desert terrain is quieter on formations and more demanding on navigation. Stay on the established path; the dark, bumpy soil crust beside it is a living layer that helps desert plants take hold.
