Saipan

Saipan is the largest of the Northern Mariana Islands, a United States commonwealth in the western Pacific. Fringed by white‑sand beaches and the deep blue of the Philippine Sea, its limestone topography has created caves, grottoes and sheer drop‑offs that have become iconic dive sites. Warm, clear water (often 27–29 °C) and visibility exceeding 20–50 m make diving here a pleasure. Highlights include the world‑famous Grotto cavern with shafts of blue light, WWII wrecks of ships and planes, coral gardens teeming with turtles and reef fish, and cleaning stations where schools of spotted eagle rays hover. Most sites are within minutes of shore, making Saipan ideal for easy day diving while still offering adventure for experienced divers in nearby Tinian and Rota.
