Santosa Island. Santosa Island is an emormous man made island just south of Singapore. It has smaller Islands surrounding it. It's a beautiful place to go. They have many attractions for tourist. like the Dolphin Lagoon, Or underworld. Apart from paying for attractions we spent a couple of hours catching rays next to their perfectly formed man-made beach. And just as a novelty they have the 'furthest most sourthernest point of asia' under their belt.
