Marine National Park and is scheduled to become a World Heritage Site - Skin-Diver Magazine has acclaimed it one of the ten most beautiful places in the world for above and under water scenery. In short - this is how a tropical paradise should look like! The fact that nobody has lived here and the distance from Phuket and the mainland is what has kept these islands in such a good shape. There are nine islands in the park and they are numbered 1 - 9 starting from the south. Because these are the oldest coral reefs in Thailand, some 5000 years old, there is an enormous diversity in species - both in fish and corals. And the visibility is the best you will find in Thailand! The dramatic scenery of big granite boulders continues under water, the west side of the islands are exposed to the south-west monsoon that brings rain, strong winds and waves in the summer, (mid May - October).
