the best tour to explore the UNESCO sites Iriomote island in half day! We spent time cruising the mangrove forest with kayak and stand up paddle and watch the waterfall and the 3 natural limestone cave. we were lucky to see the endangered Crested serpent eagle in the beginning of the tour! The guide Tomo kun was so knowledgeable about all the mangroves, flowers and animals of the island, he was also helpful and nice tour guiding with family with small child. Also he took the most beautiful pictures we couldn’t take with our phones making our day memorable one Definitely worth visiting the island if you are into the beauty of the nature and animals!
