    Words cannot describe the beauty of Panari Island. It is more like "another world" than a tourist attraction. The guides were very knowledgeable, and as a woman in her 20s, I was able to enjoy the tour while learning at ease.

    The clarity of the waters of Panari Island is truly worthy of being called "the last paradise. There were many shallow waters that even snorkeling beginners could enjoy, and I felt safe.

    It was a truly luxurious day, with a full day at sea from morning to evening, each of the three islands having a different charm, and the transportation was smooth. It was physically demanding, but more than worth it.

    The colors of the sea at Hamashima are clearer and more impressive than I had imagined. There is a beauty that cannot be conveyed in pictures. The guide's stories were interesting and gave us an opportunity to learn about sea creatures.
