The staff are very friendly and provide pick-up and drop-off service, which is very convenient. Even if you don't have a car, you can still experience it without worrying about not being able to swim. They will stop at any time to check on your condition.
We didn't have high expectations for Pumpkin Cave, but entering it was a series of delightful surprises. Besides the cave's inherent charm, our guides Jam and Shun were definitely a major reason! Jam was incredibly outgoing and friendly, sharing cultural stories throughout the exploration and guiding us to respect the local deities and culture. He made us feel like locals, giving us a truly immersive experience – it was wonderful! Shun, although a trainee guide, had an infectious energy that kept us feeling energized all day; he's a very lovely person. Thank you both for giving us a day full of surprises and joy! We love Miyako Island!
Wow, amazing! There really were sea turtles and clownfish! A truly wonderful and amazing experience! Our instructor took 158 photos for us, and the image quality was incredibly clear. They were transferred to my phone via AirDrop as soon as we got ashore. If you're nearsighted, there's an extra charge of 1000 yen for prescription goggles. In summer, you don't need to wear a wetsuit; you can change into your swimsuit first. There are restrooms next to the parking lot, but no changing rooms, so you can change there as well.
