Today’s Wonder of the Day was inspired by Morgan. Morgan Wonders, “What happens in at the post office?” Thanks for WONDERing with us, Morgan!

Do you like to go on adventures? Would you love to travel the world? Where in the world would you wander if you could wander anywhere in the world?

Some people might head to the fjords of Norway. Others may prefer to climb the world's tallest mountain. For some, the Great Wall of China could be an irresistible draw.

While adventure is exciting, some people simply want to relax on the beach. There's nothing quite like soaking up the Sun's rays with your toes in the sand. The sound of the waves crashing on the beach can wash all your stress away.

But what if you could combine a tropical paradise with exciting adventure? If that sounds like a great idea, we have just the destination for you: Vanuatu.

Located in the South Pacific Ocean east of Australia and west of Fiji, the Republic of Vanuatu consists of a string of more than 80 tropical islands. Most of the islands are inhabited and nearly 280,000 people call Vanuatu home.

The first settlers on the islands were the Melanesian people in approximately 550 B.C. British explorer Captain Cook mapped the islands in 1774, calling them the New Hebrides.

The British and the French created settlements throughout the islands during the 19th century. For most of the 20th century, the islands were jointly governed by the French and the British. Vanuatu finally gained its independence in 1980.

The islands that make up Vanuatu are mountainous and mostly covered with tropical rainforests. Many of the main islands were formed by volcanic activity. In fact, one of the main tourist attractions in Vanuatu — aside from its tropical beaches — is the presence of several active volcanoes!

Despite the chance of geological activities such as volcanic eruptions, earthquakes, cyclones, and tsunamis, tourists flock to Vanuatu to get an up-close look at active volcanoes. Mount Yasur on Tanna Island is one of the world's most accessible active volcanoes and Vanuatu tourists love to visit it, especially at night.

If you visit the Vanuatu island of Mele, there's one other tourist attraction you'll want to visit: the world's only underwater post office, located within the Hideaway Island marine sanctuary. You'll have to snorkel or scuba dive to post your waterproof postcard from paradise, but it's an experience you can only get in Vanuatu.

Vanuatu Post opened the unique post office in 2003. It's only open during special hours, though. While it might seem impractical, the underwater post office is meant to be a way of showcasing the fact that Vanuatu is a marine paradise perfect for scuba diving and snorkeling.
