Zion Canyon Introduction: Zion Canyon is a spectacular grand canyon. The steep cliffs in the valley are almost 900 meters high. The towering boulders are majestic, as well as huge buttresses, deep canyons, flat stone flats and alcoves on the cliffs. Compared with this magnificent scenery, the upper end of Zion Canyon a few kilometers away is very narrow. If two people stand side by side and stretch out their hands, they can touch the stone walls on both sides of the canyon. The deep canyon is unfathomable, and the sun can only reach the bottom for a few minutes every day.
