The flat, paved path to Cape Royal goes through sunny juniper and pine forest; signs label the types of trees and explain the ecology. The first dramatic view comes just steps from the parking lot, where you’ll suddenly see the expanse of the canyon through the trees. Soon Angels Window appears. You can get a better look by venturing off the pavement, but be very careful because the rim is not protected and the drop is sheer.

A fork in the paved path leads to a jaw-dropping overlook directly above Angels Window, where guardrails are in place. Once you’ve witnessed this, continue to the main overlook at Cape Royal, where an even broader vista unfolds. Around the large viewing platform, you’ll find signs that label the geologic formations and how they came to be. There are guardrails, but unpaved side trails can lead to more secluded and unprotected viewpoints.
