One of the best and most beautiful diving spots in Thailand? You can find it at the Similan and Surin islands, which are just as beautiful above as they are below water. While planning our trip through Thailand, I knew we definitely wanted to visit these islands - especially the lesser-known Surin islands. Since we wanted to avoid the crowds of day tourists at the Similan islands, we decided to go for a five-day liveaboard. Here you discover the best of the paradise-like Similan and Surin islands. Above and below water!
