Apra Harbor, also called Port Apra, is a deep-water port on the western side of the United States territory of Guam. It is considered one of the best natural ports in the Pacific Ocean. The harbor is bounded by Cabras Island and the Glass Breakwater to the north and the Orote Peninsula in the south. Naval Base Guam and the Port of Guam are the two major users of the harbor. It is also a popular recreation area for boaters, surfers, scuba divers, and other recreationalists.
