The Commonwealth of the Northern Mariana Islands (CNMI) is a self-governing nation and a U.S. territory located in the western Pacific Ocean. Its capital is Saipan Island. The Mariana Islands are composed of two political entities: Guam and the Commonwealth of the Northern Mariana Islands. These 16 islands are collectively known as the Mariana Islands.
Saipan, Tinian, and Rota are the three largest islands, with Saipan being the most famous. Although a war-torn island with many war relics, Saipan is now increasingly pristine and beautiful. The island is very beautiful and the water is clear, making it a leisure resort and diving destination.
Subtropical maritime climate;
November to February
Saipan
Saipan, the main island of the Mariana Islands (Commonwealth), boasts a pleasant year-round climate, abundant sunshine, fresh air, clear water, and fine sand, making it an ideal vacation and diving destination. You can also choose to embark on a full-day jungle adventure. The island is dotted with remnants and memories of World War II, and survivors and their families often hold memorial ceremonies on the island.
Battleship Island
Located west of Saipan, Gunkanjima Island is a small island surrounded by a silvery white beach. The surrounding coral reefs create a mystical play of color as the sunlight refracts through the water. The water is incredibly clear, and snorkeling here offers the chance to spot a large shipwreck, surrounded by colorful soft corals and teeming with vibrant fish. It's a truly breathtaking sight. It's a must-see.
Blue Hole
The Blue Hole, a natural cavern connected to the Pacific Ocean, was ranked the world's second best cave diving site by Diver Magazine. Home to a vibrant array of tropical fish, sea turtles, manta rays, dolphins, jellyfish, sea urchins, and more, it's even more spectacular than the underwater world. For experienced deep-sea divers, this is an unparalleled experience.
