These untainted waters shelter a coral reef that spreads across 10000 square kilometres and is said to contain 42% of the world's coral species. The world underwater here is breath-taking, and the site is known as the world's soft coral capital. The Rainbow Reef here is what you definitely should be seeing. It is where the dive attraction known as the Great White Wall is located. Expect to see about 1000 species of invertebrates, 400 marine plants, 400 corals and many species of sharks.
