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 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! The underwater visibility in Saipan is extremely high in winter, and most of the dive sites are located in shallow waters, so freediving novices can easily take great photos!
