It rained a lot in the morning, but it went ahead without being canceled, and fortunately, the rain gradually stopped, which was good. It was hard to row the kayak with my 11-year-old daughter, but the guide pulled her and took care of her until the end. There were a lot of fish in the snorkel, but there was a lot of sand, so the water was cloudy and hard to see, and there weren't many different types of fish. The guides were very concerned about safety, and it was nice that they provided simple fruits and snacks as snacks. It lasts about 2 hours and 30 minutes. I recommend it.
