It saves a lot of time waiting for buses, changing buses, and walking during the trip. You can chat and confirm attractions on the bus, and sleep whenever you want—it's so convenient!
We encountered a long weekend with three consecutive days off during the summer vacation, and the journey there was extremely congested. However, the driver was very patient and drove very smoothly throughout the trip, providing us with a very detailed and satisfying day trip.
Public transportation to Shanggaodi is relatively inconvenient and expensive, so booking this tour is the easiest, most convenient, and most economical option. Tour leader Amy is professional and considerate, making the whole experience very relaxing and comfortable. Highly recommended! 👍👍👍
