(1) Turn left and then head towards the Boulogne neighbourhood.
(2) Turn left and follow the track to a path that climbs to the right, marked in yellow.

This is one of the most beautiful viewpoints in the canyon. From the viewpoint, we recommend descending to the promontory overlooking the Grand Canyon.
