The Wonder Sea named the Dragon
A glass bottom boat ride takes you over a vibrant coral reef teeming with fish on the way to Minokoshi Coast.
At Minokoshi Coast, you will see remnants of ancient ghost nipper dwellings in the rock, what looks like mermaid caves of all shapes and sizes, sudden crevices glowing with bright blue water, before proceeding into a lush forest, and finally be rewarded for your efforts with the beautiful 360-degree hilltop view of the National Park. The view is sure to make you eager for more sea, sun and historical fun.
★Details of Tour★
Meet at Ashizuri Uwakai National Park Tatsukushi Visitor Center uminowa, where you will be given an overview of the marine park, before heading over to the port.
From the port you will take a boat across to the beach (20 minutes).on the way, you can see table corals and tropical fishes through the glass bottom of the boat.

A tour guide will accompany you to the beach and show you the strange rocks that have been formed by natural erosion.
On the second part of the tour, you will climb up a hill to the viewing platform deck, which offers panoramic views of the vivid blue waters and rocky coast of Tatsukushi Bay.
From there, the tour makes it way back to the harbor and you will again take a glass bottomed boat back to the Visitor Center to conclude the tour.
