Are you looking for the best place to snorkel and dive in Thailand or in the world? Then the Smeran islands are your best bet. This little archipelago is one of the most gripping diving areas in the world. The most striking feature of these islands is that at first glance they look like boulders scattered along the western and southern coasts of several islands. Another highlight is the picturesque white coral beach. The most interesting view, however, is beneath the waves. The most spectacular coral growth in the world can be found here. A large number of marine life inhabit the water of the Similans, including rare and endangered species.
