It's worth a visit. The scenery is beautiful, the air is pleasant, and the sightseeing route is well-planned. If you are in good physical condition, I recommend taking Route B, which involves taking the elevator to the more challenging section, climbing to the Jade Emperor Palace, then taking the cable car down across the entire canyon, walking through the valley floor, and taking a boat to finish the tour. If you are not in good physical condition, take Route A, which is the opposite of Route B!
