不要太美的藍洞，來塞班一定一定不要錯過，有的人會覺得不安全，會覺得水太冷，其實在看到藍洞的那一刻就什麼都值得了，玩的太開心了

這裏如同一個藍色的洞穴，裏面會發出藍色的光。要先走到通過一個時機，通過一段時間時間很長，並且地面也很濕滑，一定要注意安全，很多人來這裏冒險潜水，只是為了一睹這藍色的光。

藍洞在塞班島的東北角，是塞班最著名、難度高的潜水地點，這裏常可看到潛客們在此練習下水。但是一定要有證件，普通人是不能來這裏浮潛的。

Blue hole has an extremely strong attraction, people are eager to throw aside everything and jump into it, this is probably the common hobby of every diving enthusiast, this attraction is like you are sitting in the driver seat of a super sports car, eager to step on the accelerator to fly away, diving and sports cars will stimulate this impulse. Also in the evening, I stayed in our car rental place, Star Sha Hotel, Star Sha Hotel is our car rental place, very convenient, we use the qqq car rental, and we eat in the Tony Seafood restaurant, Tony Seafood, is also near our car rental, very convenient, super like, the seafood is also very delicious.

Located in the northeast corner of Saipan Island, Blue Cave is a natural cave connected to the Pacific Ocean. It has been named the second cave diving spot in the world by Divers magazine. The blue hole looks like an open-mouthed dolphin. Inside it is a huge bell-breast hole. Because of the shadow projection of rocks, it attracts more underwater creatures, including various colorful tropical fish, turtles, devil fish, dolphins, jellyfish, sea urchins and so on. It is even more beautiful than the world on the sea floor. There are two natural swimming pools in the Blue Hole, connecting the outer ocean through the submarine passage. For those experienced deep-sea divers, this will be an unparalleled experience. Affected by the sea tides, sometimes the level of the cave is quiet, sometimes the waves are fluctuating, so swimming and diving in the cave should be very careful. In addition, the cement steps of the Lower Blue Cave are steep and slippery, so it is better to walk slowly. When we went to Saipan Island, we also went to a Chinese restaurant: Tony Seafood (Tony Seafood). The environment was very good. The seafood was delicious. The owner was also very good. The key point was that the seafood was delicious. I was very satisfied that the restaurant that we could eat was so good that I would recommend it to my boss.

The Grotto is the world's second cave diving site, located in the northeast corner of Saipan Island, is Saipan's most famous but difficult diving site, it can be said that "without the Blue Hole, Saipan will not be counted. It is said that diving at 5 a.m. is bound to encounter all kinds of turtles, sharks and tuna. After wearing all the equipment, we took frog shoes and walked down the cliff with ducks down more than a hundred slippery steps. It's not fun to fall steeply and slippery. It's really heartbreaking. When we reached the bottom of the steps, we had to pull a stainless steel rail and drag a hemp rope to jump onto the reef at the entrance of the cave. Although the straight line distance is only 10 meters, but still need to catch the gap between two waves to complete the jump, otherwise it is not as simple as wet body, falling down is easy to be directly hit by strong waves on the reef injury. It's really dangerous to wear frog shoes on slippery rocks. I fell hard anyway. Fortunately, the cylinder landed first, otherwise the overseas medical insurance would really be in operation. The reef is more than 2 meters away from the sea. Many snorkeling tourists have psychological barriers. They dare not jump. To be honest, I haven't jumped over this height, and I'm a little worried. With one hand on the mirror and headphones, and one hand on the back of the head, they stepped into the sea. The spherical top of the Blue Hole 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, including colorful tropical fish, turtles, devil fish, dolphins, jellyfish and sea urchins. The average water depth of the Blue Cave reaches 17 meters and the deepest reaches 47 meters. There are three channels connecting the Blue Cave and the outer sea. The light penetrates through the 65 passages of the outer sea into the cave. The Blue Cave pool shows a light blue luster, which is quite magical. Affected by the tide, sometimes the level of the cave is quiet and sometimes the waves are fluctuating. So swimming and diving in the cave should be very careful. Real infinite deep blue. The first time to feel such sapphire. Such visibility. Such penetration.
