— What You Can Expect —

Ryugu Castle (dragon castle), popularly known as Pumpkin Hall, is a rare limestone cave accessible only during low tide by kayak. To enter the cave, you will need to swim through its entrance. Once inside, you’ll find remarkable pumpkin-shaped stalactite formations, naturally created over time by the dissolution of lime in the stratum. As you climb up Pumpkin Hall, discover a spacious area resembling terraced fields within the limestone cave.
