Underwater Post Office

Welcome You

The Underwater Post Office is located in the 3-meter deep waters of Hideaway Island Marine Reserve and opened in May 2003

During business hours, a buoy with a flag will float on the water surface. The staff of the underwater post office all hold certificates of ocean free diving and are responsible for collecting mail and stamping stamps. Tourists purchase carefully crafted waterproof postcards here and immerse them into the underwater mailbox. The postman regularly collects these postcards and sends them to various parts of the world.
