Blue Cave Snorkeling
This is a snorkeling tour around the popular and unexplored “Blue Cave! As the name suggests, the inside of the cave is shining blue. Let's swim with a lot of fishes!
Landing & Snorkeling at Phantom Island
Phantom Island” is a sandy island in the ocean on the west side of Ishigaki Island. The name comes from the fact that the shape of the island changes depending on the tide level. The surrounding sea is called “Seokusei-shoko”, one of the largest coral reefs in Japan! It is like a natural aquarium.

They cancelled last minute and did not give a refund or cancel the trip so now I am stuck fighting to get a refund.

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.

Initially we tried to escape getting our picture taken, but in the end we were happy that Naomi capture our memories. She was very attentive and accommodating. True customer service at its finest!

A little sad blue cave was cancelled, but still had a great time! The guide got great photos for us, too!

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.
