The scenery is beautiful; the highlight is the boat ride inside the cave. I recommend entering from the west and exiting from the west. Parking is convenient at the west gate. First, take a 3-minute sightseeing bus, then walk for about 10 minutes, then take another 5-minute sightseeing bus to the Natural Bridge to board the boat. If you have a one-way ticket, make sure to climb the stairs on your right when you reach the boarding area; the rest of the way is downhill, which is more convenient for the elderly and children. Finally, take the boat back from the east gate to the west gate. If you take the boat to the east gate first and then walk back to the west gate, it's all uphill stairs and will be very physically demanding!
