Climb aboard the glass-bottomed Jacques Dolphin
Captain Kihachiro Aratake was the first person to discover the monument and his intimate knowledge of the site ensures you will enjoy everything these fascinating and enigmatic underwater ruins have to offer. When sea conditions are too rough to visit the site the tour takes in some of the other spots of stunning natural beauty around the island and visitors can enjoy a DVD of the monument on board the boat.

We also offer a transportation service to and from your accommodation or the airport.
