Arriving at Shabang Pier, all guests who go to the underground river will take a crab boat at the pier to reach the island where the scenic spot is located. Sao Paulo The Underground River National Park implements strict visitor count management every day, so it is necessary to make an appointment in advance. After the crab boat is to be distributed, the tour guide will marry us and must remember the number of the crab boat you are sitting on. Because the boat is in the scenic spot, you have to take a few boats to come out after the tour. From the pier to the scenic spot, the boat will take about 30 minutes, and along the way you will see the steep karst limestone mountain wall, and the mysterious underground river is hidden in the bottom of the mountain. The sea is a dreamy emerald blue, and our crab boat will eventually park on a shoal~
