What travelers say:

Don’t miss the beautiful blue hole. You must not miss it when you come to Saipan. Some people feel that it is not safe and the water is too cold. In fact, everything is worth it the moment you see the blue hole. It’s so fun.

Additional Information


The Grotto(Blue Hole) is a natural grotto connected to the Pacific Ocean and a scuba diving paradise in Saipan. The grotto's exterior exhibits a mysterious deep indigo blue; on the inside, there is a colossal cave of stalactites and two natural swimming pools connected to outer waters via a submarine passageway. Illuminated by beams of light from outer seas entering the cave through the passageway, the pools inside the Grotto give off a mysterious pale blue light, making both snorkeling and deep diving here an extraordinary experience.
