There is something magical about these five islands in the southwest of Koh Samui. No matter where you are, you only ever see 4 of them. That's why the small archipelago is also called 4 islands - 5 islands (Ko Si - Ko Ha) in Thai.
But what makes them really special is that they are home to thousands of birds that build their nests in the rocks. These nests are coveted goods for Chinese gourmet markets and are collected under life-threatening circumstances.
