The number one thing you'll probably do is book your flight if you want to travel to another country. But in some countries, you won't be able to fly directly.

Vatican City, the smallest country in the world, as a 109-acre area in the middle of Rome, doesn't have its own airport, but visitors can easily get there via Italy's capital.

Similarly, San Marino, the fifth smallest country in the world, is also surrounded by Italian land. It has a population of a little more than 33,000 and sits just nine miles from Federico Fellini International Airport in Rimini, Italy.

The second-smallest country in the world is Monaco, with a population of more than 38, 500. To get there, you'll have to go through France's Nice Cote d' Azur Airport, which is just a 25-minute car ride away from Monaco. Perhaps that's why developers didn't bother creating anything like a short flight.

Interestingly enough, the third and fourth smallest countries, Nauru and Tuvalu have their own airports, but the fifth and sixth smallest don't We already mentioned San Marino, and to get to Liechtenstein, you'll have to go through Switzerland's St. Gallen-Altenrhein Airport, 24 miles away from the capital.

Situated in a mountain range valley, Andorra has too much difficulty in building an airport runway. But for visitors there is no difficulty in going Andorra. Both Spain and France have access to Andorra. The closest way to Andorra's capital is Girona-Costa Brava Airport in Spain.
