Dimple is the underwater hump to the west from Saipan. Immediately at the beginning of your dive you will see a lot of red snipers. At the base of the formation, you will meet hundreds of marine species: moorhens, rays, sea turtles, and more. If you bring some food, you will enjoy by feeding fish. You will be surrounded by a swarm of thousands of little fishes that will fly around you like butterflies. The depth of this site varies from 40 to 130 feet.
