各航路乗船券（燃料サーチャージ別途） - 石垣島発 往復フェリーチケット＜竹富島・小浜島・黒島・西表島・鳩間島・波照間島＞ by安栄観光

In winter, I would actually recommend buying the ticket on the day you plan to go out. It’s cheaper than buying it at the counter . But if you buy the more expensive one (Uehara), it doesn’t open very often(but wont refund), so I recommend buying the round-trip ticket in the morning on the day you plan to take the boat. prepare some extra cash because they will charge a fuel surcharge. (Uehara has a higher fuel surcharge as well, which is why I recommend buying the ticket only when you’re sure about where you’re going.)
