Vanuatu's Hedway is a beautiful island. The sea is crystal clear, and the most exciting thing is to see many large fishes, colorful living corals, cute colored fish around, and the charming underwater world is lingering. It is worth mentioning that there is a world-class undersea post office, stamp collectors can buy a special card, write it in a special pen and put it into the mailbox three meters underwater, or the management to help you to deliver, this will be a permanent memory.
