Whilst many water activities are available in Koh Samui, one of the best is snorkelling as Koh Samui is gifted with an infinite blue ocean, crashing waves and serene waters underneath which lie scores of colourful living species waiting to be admired. Go deep into the ocean beholding coral reefs on a snorkelling experience where all this can be seen, such as at Choeng Mon, Ao Phang Ka, Silver beach and many others in Koh Samui.
