1. Okinawa: Ishigaki Island Snorkeling Cruise with Drinks
Swim and snorkel through the amazingly clear Ishigaki green ocean on a boat tour. Depart the harbor in the morning and take the 40-minute ride to Hamajima, also known as the Phantom Island. Enjoy unlimited drinks on board and, if you've selected the charter option, listen some background music along the way. Discover this island made of a sandy beach and emerald green sea. Continue sailing and enjoy a stop for snorkeling to see beautiful corals and various kinds of fish. You may even get lucky and spot some sea turtles.
