This place is like a blue cave with blue light emitting inside. It is necessary to go through an opportunity first. It takes a long time to pass, and the ground is slippery. You must pay attention to safety. Many people come here to take risks and dive just to see the blue light.
i think the view under the sea will be more beautiful than we saw.
The Blue Cave is located on Saipan and is a natural cave connected to the Pacific Ocean. It is a deep cave formed by long-term erosion and collapse of the limestone seabed formed by coral reefs. The sea water fills the deep hole through the waterway of the cave body. As the cave lengthens the light path, the blue and violet light are scattered more thoroughly and appear bluer, which becomes the so-called blue hole.
The Blue Hole is located in the northeast corner of Saipan. It is the most famous and difficult diving site in Saipan. Submersibles can often be seen here to practice diving. The most amazing thing about the Blue Hole is that the limestone has been eroded and collapsed for a long time by seawater, forming a deep hole. The Blue Hole has 3 connected waterways to the open sea.
