Sea in | Angthong Islands

The emerald green sea has two viewpoints: the lower and the lower levels. It takes about 10 minutes to go up and see the view. The inner sea is a relatively round basin similar to a small lake, surrounded by limestone mountains in a circle until it becomes a basin with water inside. The width is about 250 meters in diameter. At first glance, it looks like a lake, but it is not completely closed because there is a channel that connects to the outside sea (the Gulf of Thailand) that surrounds the limestone mountains. In some places, it is clearly a cavern, which is caused by some limestone being washed away and dissolved by water, creating caves and channels for seawater to flow in and out of the basin. This geographical feature makes it look like there is a sea within the surrounding mountains, which is the origin of the name of this place, the inner sea. #Angthong Islands #Inside Sea #Mae Koh Island #trip free accommodation
