Koh Munnai in Rayong Province is truly the gem of the eastern sea! It is the largest island in the Munnai archipelago and is also the closest to the mainland, making it very easy to travel to. The atmosphere is calm and perfect for relaxation. Here, it's not just about beautiful seas and clear waters; it is also a very important sea turtle conservation area, with a conservation center where you can learn about turtles and get up close to these adorable creatures. Getting to Koh Munnai is not difficult at all; you can rent a boat from either Mae Kam Pong Bay or Pak Nam Prasae, which takes only about 30-40 minutes. Once you arrive, you'll see the sparkling clear sea with tiger fish swimming around to greet you. The island has nature trails for exploring the lush forests, and during low tide, there are beautiful sandbanks perfect for taking photos. It's worth noting that there is no overnight accommodation here, but you can visit for a day trip from 8:00 AM to 5:00 PM. If you want to experience this peacefulness and unspoiled nature, you absolutely should not miss it!
