Northern Mariana Islands

The Northern Mariana Islands are a U.S. commonwealth in the Pacific Ocean. Saipan, the largest island, is known for its sandy shores and mountainous landscapes. In clear waters off its west coast is the tiny, coral-fringed Mañagaha islet. On Saipan's northeast coast, turtles inhabit the Grotto, a cavern dive site. Nearby, memorials mark Banzai Cliff and Suicide Cliff, sites from WWII's Battle of Saipan.

The Northern Mariana Islands are an easy warm-weather escape northeast of Guam. Once you’re on the islands, the only difficult decision you’ll have to make is whether to sunbathe on a beautiful beach, try your luck at a casino, play golf with dazzling views of the Philippine Sea or go scuba diving in a World War II shipwreck. Then again, there is no reason why you can’t do them all.
