Huantan Island is very beautiful!
Especially when the weather is clear
The white sand beach + jelly sea are really too beautiful!
The ride to Mermaid Island is long (the pier is far from the city), and the boat ride takes 30 minutes
The ride to Huantan Island is short (the pier is close to the city), and the boat ride takes 1 hour
Ps: The boat is really shaking, if you are prone to seasickness, you should choose Mermaid Island
Also, the sea water here is too salty, and snorkeling babes should be prepared to drink a lot of sea water~
But you must experience it when you come, it's really great
The island and mountain facilities are basically complete, so don't worry too much, but there is no signal~
