The scenery is pretty good. The main thing is to take a boat trip. Vietnamese boatmen row manually, and one boat can seat about 4 people. Passing through various caves, the main thing is to enjoy the scenery formed by various karst mountains and caves on the boat. The whole journey takes about 2 hours. If the weather is good, the scenery is still very good, but it is a bit sunny on the boat, so be sure to do a good job of sun protection. There are also umbrellas on the boat to block the sun.
