The Grand Canyon must have been beautiful, but unfortunately, we encountered a very foggy day, so we couldn't see much of the scenery from the mountain. The Yunlong Ground Fissure, which we visited in the afternoon, was unaffected by the fog and was quite spectacular. Even though we bought tickets for the cable car, elevator, and other amenities, we still almost broke our legs from all the walking, which will affect our itinerary for several days. I recommend that if you're not very confident in your hiking skills, you buy a combined ticket that includes the cable car, elevator, and escalator.
