It was exciting to try diving for the first time. The blue hole is very beautiful, the spherical top wall is quite spectacular, and even can accommodate a church. The water inside the cave is clear and bottomless. The projection of rock shadows attracts more underwater organisms, such as colorful tropical fish, turtles, devil fish, dolphins, jellyfish and sea urchins. The average water depth of the blue hole reaches 17 meters and the deepest reaches 47 meters. I went to Saipan Island for a tour and made a strategy to share with you.
