Vanuatu Post has created an official Post Office with a difference. It is the world's only Underwater Post Office. Situated within the Hideaway Island marine sanctuary, the Post Office sits in around three metres of water and both divers and snorkellers are able to post special 'waterproof postcards'. If snorkellers cannot duck-dive down that far, Hideaway Island staff will be on the spot to help out. Unbelievably Vanuatu Post has established a post box near the fiery rim of Mt.Yasur's crater, where mailing a letter is a hot experience! Imagine molten lava exploding in the air metres from where you are writing and sending your postcard! This is what Volcano Post is all about.
