Post offices are almost becoming extinct with the coming of e-mails. Who wants to waste time waiting for a stamp at a post office while you can send an email within seconds? However, visiting the below listed post offices could turn to be quite an adventure.Peach Springs and Supai, AZ
This town has a population of around 1,000 people and therefore you expect a small post office. Surprisingly, it houses the only walk-in freezer in a post office in US. The peach Springs Post Office also has the responsibility of supplying perishable groceries to the bottom of The Grand Canyon. This is accomplished by the use of a mule train. This mule train is a caravan of 50 mules and horses guided by riders. Each mule ferry 200 pounds of mail and packages. They make their way down to the base and then back up with the outgoing mail and trash.Mount Everest Base Camp, Nepal
The China Post Office which is found here sits at 5,300 meters and is said to be the tallest post office in the world. Due to extreme weather conditions at this altitude, it only operates from late April to August annually from 10 am to 6 p.m. to compensate for the transportation challenges; it will cost you $ 1.45 to mail a postcard all the way to the UK.Underwater Post Office, Vanuatu
You can either hand your postcard to the staff or buy a water proof card and dive under water to hand it to the scuba equipped staff. This post office is 10 feet below the surface.Aogashima Island, Japan
This isolated island has a population of less than 200 residents. This island is actually a volcano. People mail their letters a few steps from molten magma. The tiny post office transmits mails to and from the mainland.J.W Westcott II, Marine Post Office
The J.W Westcott II is a mail boat that is 45-foot long. It's probably the only floating post office. It serves freighters travelling across Detroit River.Floreana Island
This is not even a real post office since nothing gets stamped or mailed from here. However, travelers drop their post cards at the post office bay and in return sort through the other postcards the previous travelers left.
