Johnstons Island

Johnston Island sits in one of the most remote stretches of the Pacific, roughly halfway between Hawaii and the Line Islands — so if you're anchoring off here, you're genuinely in the middle of nowhere. The isolation is the whole point: this tiny atoll sees almost no traffic, and access is tightly restricted by the U.S. government, making it one of those rare spots that exists more as a waypoint on a long passage than a destination in its own right.
