    Enjoy Nature, But Never Ever Swim Here Alone.

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.
