Arriving at Huantan Island by boat in an hour from the wharf near Magellan Hotel, big waves will be thrown all the way. It is suggested that before going to sea, Huantan Island should not eat too much. It belongs to private islands. It has only been developed and opened up in recent years, and the island should be booked in advance. Therefore, the number of passengers who go to the island every day will have a little strong wind to control the sea, even if there are many waves at the snorkeling point. So instead of going snorkeling twice in the morning and going to two different places in the afternoon, I suggest buying a bottle of bread crust (2 cents) in the pier restaurant, which can attract many fish to swim around and guide tourists. The old diving coach also guided me to find Nimo, the clown fish.
