Miyako Island: Pumpkin Limestone Caving & Kayaking offers a fascinating blend of adventure and natural beauty right in the heart of Okinawa. For $66 per person, you can spend a few hours exploring a limestone cave known as “Ryugu Castle,” paddle a kayak along shimmering waters, and enjoy the thrill of climbing through a mysterious underground world.
What we love about this experience is how it combines physical activity with awe-inspiring sights. The chance to see pumpkin-shaped stalactites inside the cave is quite a visual treat, and paddling through the calm waters adds a refreshing touch to the adventure. Plus, the fact that your guide will take free photos with a waterproof camera means you’ll have tangible memories without the hassle of taking your own pictures.
A possible consideration is that the cave itself is quite small, which might feel cozy rather than grand, especially for those expecting a cavernous adventure. Also, the tour is weather-dependent—if the tides are high or safety can’t be guaranteed, the tour may be canceled or rescheduled.
This tour is best suited for active travelers who enjoy a hands-on experience, aren’t afraid of getting a little wet, and are looking for an authentic, off-the-beaten-path adventure on Miyako Island. It’s particularly appealing if you’ve got kids aged 7 and up or if you’re traveling with friends and want a playful yet memorable outing.
