9. Underwater Post Office, Vanuatu
The tiny island nation of Vanuatu is known for its exotic beaches and rich volcanic landscape, but it is also home to the world’s only underwater post office. If you’re in the area and hoping to send a waterproof postcard home, you’ll be able to dive down some 150 feet off the sandy coast of the idyllic Hideaway Island Resort to reach the funky post office. Gimmicky, sure, but fun nonetheless.
10. The Marianas Trench
Unless you’re as wealthy and determined as director James Cameron or a lucky aquanaut, the Marianas Trench is certainly off limits, but it’s worth a mention in this list owing to the sheer extremeness of its environment. The Earth’s deepest point is near Guam. It sits at just under seven miles, and the pressure is more than 1,000 times that of sea level. However, even this inhospitable environment where the light of the sun never reaches is home to many species such as flatfish and shrimp. It would be a fascinating experience to go where few have explored before. Have you been to any of these underwater wonders?
