Fantastic experience - My friend and I went on both the Phantom Island/Sakura beach trip. It was so much fun snorkeling and seeing the many types of fish and creatures. We even saw 2 sea snakes and our guide, Sebastian captured it on camera! He is a good communicator and picked us up from the Ferry port terminal. I would recommend this excursion to anyone with a sense of adventure.

Great times with great people in paradise - One of the most beautiful places on earth. The blue cave portion of the trip was amazing, just being there left me with a great sense of calming peace. The snorkeling off the coast felt like we snuck into an aquarium at an academy of science, there was so much life and it was so pristine and clean. Phantom island was so gorgeous we felt like we were inside of a post card photo. Juan Sebastian and Moe, our guides throughout the day, and the rest of the crew were awsome. They helped me learn so much Japanese and they spoke English well. Thank you so much!! Hope to see you soon!

Great Adventure with Awesome guides! - What an amazing experience and amazing guides!!! Our guide Kota was amazing!!! Couldn't have been more friendly and made sure we got ahead of every other tour. He dove down deal and got amazing pictures for us!!! Made sure we had the times of our lives and made sure we were safe! The tour was amazing of the cave and the snorkeling was top notch seeing the most amazing fish! Only downside was the AC wasn't that good on the ride and it was a scorcher of a day!

Amazing experience! - Ishigaki Snorkeling Tour at Blue Cave and Phantom Island is an absolute must-do for anyone visiting Ishigaki! From start to finish, the experience was seamless and unforgettable. The tour guide, Mahiro, was super nice, he made everyone felt comfortable and confident in the water. The Blue Cave was a mesmerizing sight, with its stunning azure waters and vibrant marine life. Snorkeling and Phantom Island were equally breathtaking, offering a glimpse into the diverse underwater world of Ishigaki. The equipment was provided and the small group size allowed for a personalized experience. Overall, this tour exceeded all expectations and was definitely memorable. Highly recommend!

Amazing and well organised - The tour itself was amazing and the snorkelling spots were beautiful! Blue cave was our favourite, it felt like we were in finding Nemo. Although the corals were mostly dead, there were plenty of fish and we were lucky to see a turtle. Our tour guide, Arai-san was very knowledgeable and was passionate about the island and wildlife. He took care of us really well and we felt safe in his care. He spoke good English too! He even recommended us great lunch and dinner spots during our stay. And he also took a lot of photos of us, the marine life and sent them to us via WhatsApp/LINE. Will definitely come back, highly recommend! Thank you Arai-san and the adventure pipi team.

Great family experience - We had a wonderful day with the incredible staff of Ishigaki Adventure PiPi. We snorkelled in the morning and visited Phantom Island, then had 2 hours free for lunch before heading out to snorkel at Blue Cave. We saw many fish and both our guides took great care to make us feel safe, welcome and well-informed in English.

Not as described, left disappointed - I received notification that the Phantom Island part was cancelled due to high winds. Okay, I get it. I was told that snorkeling at Osaki beach would be substituted. Okay. The meeting time and place were the same. Received a message that read, "Pick you up on o o" I received notifications that it started at 8:00 that morning on my phone. I was at the meeting place at 7:45. It was close to 8:30 when I contacted the company and was told it was at 9:00. I didn't find out until after snorkeling that we were not going to Blue Cave and that my afternoon had been substituted for the mangrove tour on canoe or paddleboat. Snorkeling at Osaki beach was great! I thought this was a whole day affair, as in we would go to the next location. Nope! We were brought back to the terminal, told to find somewhere to eat lunch, and meet back at 1:00 for the mangrove tour. When I asked about Phantom Island/Blue Cave snorkeling the next day and the day after, I was told that it's cancelled due to winds and that it would be cancelled for the month since it's close to winter. Then why have it on the Viator website as an activity to book if it is just going to be cancelled and substitutions offered. Even the refund seemed sketchy. I've already paid on my credit card and was told the refund would go on my credit card and I would have to contact the credit card company.
