“It would have been very appreciated to see the 59 year old age limit clearly stated on the first page of the website. I know that information is noted later, but, had we known right away, we wouldn’t have taken the time to go past the first page. It was very disappointing to not be allowed to snorkel, especially since we are both swimmers, much more comfortable in the water than some of the younger family members.”

4.Okinawa Ishigaki Kabira Bay SUP or Canoe and Blue Cave Snorkeling

“This was the coolest thing I’ve done. The staff supplies you with a life vest, water shoes, flippers and goggles. There is one guide leading the way and one guide behind us. 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!”

“Kanu morgens / nachmittags schnorcheln. Guides: Hiroki + ? / Aoi Beides war großartig und die Guides waren top. 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🙏”
