Our snorkeling trip coincided with a typhoon. Although the typhoon didn't actually make landfall, the Japanese authorities closed the Blue Cave, prohibiting snorkeling and diving. So we went to a nearby beach instead. The water there was very calm and safe, which reassured us, although it was a little disappointing! Our family of five, three of whom can't swim, had signed up for a group snorkeling trip, but due to insufficient participants, it became a private tour. The instructor explained the activity entirely in Chinese, providing very clear instructions. He had us change into our wetsuits and then led us to the shore, carefully demonstrating how to wear masks and use snorkels. Even non-swimmers shouldn't be too nervous; he guided us while we held onto the float. The process was actually very easy. The water was very calm, and the depth wasn't great; we could touch the bottom in most areas, so we weren't afraid. Later, we just let go and swam easily! The water was very clean, and we saw many different kinds of fish. The instructor even gave us some bait to feed them! He took photos and videos throughout the trip and sent them to us later! I can't swim, but this was my third time snorkeling, and I felt it was perfect for beginners. Although I'm not sure about the actual conditions at Green Cave, based on my experience, snorkeling is a very relaxing activity with no need to be nervous or afraid! Thank you to the instructor for leading the way; my family and I had a great time! ☺️
The itinerary was well-organized, the tour guide was very friendly, the driver was very skilled, and the weather was perfect. My family and I had a very enjoyable visit, and it's also suitable for senior citizens.
