Introduction to Lipa Observation Deck: Lipa Observation Deck is one of the most spectacular attractions on the south face. It is a good place to watch the panoramic view and sunset of the Grand Canyon. Here, you can have an unobstructed view of the scenery to the west of Uka Rapids. To the northeast, the sheer cliffs known as the Palisades Desert serve as the natural southeastern wall of the Grand Canyon.
