The water was very calm and was easy to swim. I’d recommend taking your time while in the ocean. It can get tiring a bit, but feel free to just relax, float and enjoy the time. Around 11 am, we went to kabira bay for lunch which was nice also. Definitely recommend!”

Beim Kanu fahren konnte man viele Fotos machen und Tiere sehen, besonders beim Laufen durch die Mangroven. Schnorcheln war wegen dem Wellengang und 0 Erfahrung etwas Anstrengend, sodass Aoi mir auf halber Strecke half, indem ich mich am Rettungsring festhielt, nur noch per Beinbewegung schwamm und mich aufs Schnorcheln konzentrieren konnte. Vielen Dank🙏”

8.Iriomote Mangrove SUP and Snorkeling at Coral island

★★★★★★★★★★3.4 · 11 reviews · 6 hours · from $96

Spend six hours on Iriomote with guides such as Yuma, combining a speedboat ride, coral-reef snorkeling, and SUP or canoeing through mangroves. Equipment, showers, photos, and insurance are included. Expect a life jacket throughout, changing activity order, and possible weather cancellations.

“Very friendly as usual in Japan. However, it's important to know that around 40% of the coral is dead is on most reefs. BE AWARE: you're required to wear a life vest even in the water, which makes swimming difficult and uncomfortable. In fact, it's not really snorkeling since you can’t dive. The SUP tour through the mangroves is nice, but you won’t see much of the island itself—so overall, it’s quite an expensive tour for what you get.”
