About Pearl Harbor

Pearl Harbor is one of the most visited historical sites in Hawaii, drawing visitors to the USS Arizona Memorial, the Battleship Missouri, and the Pacific Aviation Museum on Ford Island. The military complex sits on the shores of a large natural harbor on Oʻahu's south coast, roughly midway between downtown Honolulu and the leeward (west) coast.

There are no swimming beaches at Pearl Harbor itself — the harbor is an active military installation. But the central location makes it easy to reach beaches in several directions after a morning at the memorials. The nearest large beach is Ala Moana, about 20 minutes east toward Honolulu, while the calm man-made lagoons of Ko Olina are about 25 minutes west. Water quality varies significantly between options, so checking conditions before choosing is worthwhile.
