Let’s venture over to a small secret beach, accessible only by boat, to drift on banana boats and play in the sea while enjoying coral reefs.
Bannoko Beach is a small beach, only a stone’s throw from Minokoshi Beach; part of the Tatsukushi National Marine Park, boasting of beautiful sand and only accessible by boat.

Experience the speed and feel the sea breeze on the banana boat. At Bannoko Beach, you will enjoy snorkelling with fins.

This popular activity is best geared for those who feel that vacation means having a time to relax, heal, and feel rejuvenated. Swim freely or explore the sea of coral reefs. As you will be required to wear a personal floatation device and are accompanied by our instructor at all times during the activity, even those unfamiliar with water can enjoy this time in safety and with peace of mind.
