Pick-up: They come to the hotel at the appointed time. More than 90% of the tour participants were Chinese. I was surprised that the tour guide explained everything in Chinese. English is also available for individual inquiries. Anti-sickness medicine was also prepared. We departed on a catamaran that can carry 30-40 passengers. The waves were low and comfortable. The boat was sturdy. There was one person who was seasick. We had about an hour of free time at Coral Island. The water was much cleaner than Patong. We were able to borrow a life jacket on the island without asking for a rental fee. I think it was free because no one asked for a rental fee. It's better to have underwater goggles. When we returned to the boat, water and canned juice were distributed. They were distributed three times during the tour, so we didn't have any trouble getting a drink. We ate on the boat. The taste was average. The beach at the pier of Racha Island was narrow, but the waves were calm and the water was clean. You can also request a diving experience there. About two people did diving. The tour guide invited us to go to another beach, and most of us, including me, went to the other beach. We got on a Kubota tractor with a loading platform. The destination was a paid beach. We had about 30 to 40 minutes of free time there. The waves were high that day, the water was murky, and there was a lot of garbage floating in the water, so we couldn't enjoy it. It would have been better to stay and play on the narrow beach at the dock. Or maybe a diving experience would be good. (I think the diving experience costs an additional 7,000 JPY.) We got on the boat again and went out a little further offshore and snorkeled for about 40 minutes. They lent us life jackets, underwater goggles, and snorkels. They also had disposable replacement mouthpieces. We scattered bait from the boat, so there were quite a few fish gathering there. There were not many fish anywhere else. After snorkeling, we got on the boat and moved. Sushi and fruit (watermelon and pineapple) were distributed. Two pieces of sushi per person. Of course, it was sushi in Southeast Asia. It wasn't authentic sushi. But it was pretty tasty. We took a nap on the boat while traveling. On the way, we anchored offshore and went fishing. Several people caught fish. We returned to the port around 6 o'clock. For me, the catamaran trip was quite comfortable and it was a satisfying tour. However, Racha Island was disappointing, so I'll give it four stars.
