Things to do · Destination Guide
Lagoon wrecks, reef walls, a dramatic Grotto and an island worth exploring above water.
Pick an activity mode to compare signature sites, skill fit, and gear planning notes before you lock your trip.
Saipan combines reef training terrain at Lau Lau with a very different second act: the Chinsen wreck and Maritime Heritage Trail inside the lagoon, reef mounds at Ice Cream and Dimple, and deeper walls such as Naftan. Fishguyz and MSC advertise beach, boat and instruction products, supporting a local-operator format. The Grotto has dangerous current and submerged passages, and the northern Banzai/Wing sites are seasonal and exposed. Operator screening takes precedence over any blanket tourism claim that an entire site works for everyone. Access, equipment, weather, water advisories and certifications must be confirmed before booking. MVA dive sites; Fishguyz; MSC.
Lau Lau Beach
Popular training-style shore reef with smaller marine life and possible turtles/nudibranchs.
Obyan Beach
Southern sand-and-reef entry, accessible by beach or boat, with an outer reef transition that requires a guide to select the right depth and route.
Battle of Saipan Maritime Heritage Trail
WWII aircraft, craft and other remains span named lagoon sites between Garapan, Tanapag and Managaha, with southern lagoon artifacts.
Ice Cream
Shallow-topped coral mound on west side, where the MVA notes eagle rays and schooling reef life.
Dimple
Fish-rich western seamount with profiles reported to about 40 m.
Naftan Point
Southern boat wall, shallow along its crest but dropping beyond standard recreational profiles; the boat guide chooses route/depth.
Chinsen / Shoan Maru
Historic merchant vessel remains in the western lagoon.
Grotto
Photogenic blue-water basin but high-consequence stairs, surge, strong current and potential overhead hazards.
Banzai Cliff
Boat-exposed northern wall associated with strong currents/waves.
