Blue Diamond Island is a national-level coral protection area in Thailand. It is located in the Andaman Sea in the Indian Ocean and is located at the southernmost end of Phuket. The island is very small and exquisite, small enough to exceed your imagination, only 1 square kilometer, walking around the island, up to 15 minutes, it is too small! White, shiny like diamond sand, is imprinted with seawater from transparent gradient to deep blue. White sand is delicate and soft, like falling snowflakes, draped on the beach. The colorful beach tent is a dazzling splicing of the beach.
