The Similan Islands are blue and clear, with large coral reefs and many marine life. They are among the top ten diving sites in the world, with more than a dozen famous diving spots. The Thai government has been striving to maintain this beautiful paradise for many years, and local people have a strong sense of environmental protection. We arranged two snorkeling trips on our day trip and had the opportunity to get close to the Haizhong Garden. The water quality here is much better than the Great Barrier Reef in Australia. Even if you can't swim, you can easily see the colorful fish swimming between the corals under the protection of the tour guide and the crew. Take a basic waterproof camera or put a waterproof case on your phone to record these beautiful pictures. Diving enthusiasts are strongly advised to stay in Similan for a few days and they will be very enjoyable.
