Saipan’s diving sites focus on historical sites, and there are downed fighter planes and sunken ships from World War II in the nearby waters. In addition to military ruins, you can go to The Grotto, the world’s second-ranked blue hole, to experience the “Jesus Light”. Free diving and cave diving enthusiasts must not miss it. Friends who want to see “big things” can go to Icecream / Eagle Ray Point. If you are lucky, you may encounter a large group of Eagle Rays swimming above your head! Saipan’s unique underwater ecological environment breeds rich and diverse marine life. The underwater visibility is extremely high, and the depth is generally about 10-20 meters. Most diving sites have gentle currents and are suitable for novices.
