The first stop, Snake Island, is said to have many kinds of snakes. The tall trees hide inexplicable dangers. When singing, they always worry about accidentally falling asleep with poisonous snakes. The tour guide picked up the big rocks by the sea. The blue and white sea snakes hid under the rocks from the hot sunshine at noon. The water on Diga Island is clear, the beach is fine white sand, the shore is dense tropical trees, and a trestle extends into the sea. When the sunset obliquely shines, a couple of lovers quietly snuggle together, watching the sun slowly fall into the sea, the sea and sky reflect red, the lover has become a red silhouette... The coral of Diga Island is just ordinary, which is a little worse than that of Sima. The coral is not good and the fish are not much. In the afternoon, we went through the muddy mountain road to visit the mud bath. After raining in the tropical rain forest, the path became slippery and muddy. Several girls wore slippers and often took two or three steps back. Soon, the whole body was covered with mud. The mud bath is said to be volcanic mud with cosmetic effect. We saw tourists soaking in mud all over their bodies except their eyes and enjoying themselves.
