I booked a tour to the Similan Islands because I heard you can see beautiful, crystal-clear waters there! ★ In conclusion, it was absolutely fantastic!!! I was so touched by how kind all the tour guides were (;;)♡ They spoke to us Japanese people in Japanese, took wonderful photos for us (both on land and in the water), remembered our names and were so considerate—they were all wonderful people! It takes time to get there, but it was well worth it for the wonderful memories we made! Breakfast, lunch, water/juice and snacks were provided on the boat, and snacks were also provided after the tour, so you don't need to bring anything! On the way back, it was raining and the boat was quite bumpy, which surprised me, but we made it back safely 🙂↕️ I was fine, but if you're worried, it's a good idea to bring motion sickness medication! (I think you can also get some from the tour guides!)
