Today, airplanes have become the only option for international travel, but there are some countries where there is no airport and it is not surprising because the area of these countries is enough to turn the whole country into an airport. Even the airport will not be completed, that is, for these countries you can say. According to India Times, the first of these is Monaco, the second smallest country in the world. The total area of Monaco is 2.02 km2, so it is not possible to build an airport there. France's Nice Cote d'Azur Airport is the nearest airport to Monaco from where the people of this country travel by air.
The other is San Marino, a small landlocked country in the middle of Italy. Those wishing to travel to this country have to book tickets for the Federico Fellini International Airport in Italy. The third country is Andorra, which shares borders with Spain and France. Spain's Barcelona El Pratt and France's Toulouse Airport are the nearest airports to Andorra from where the people of this country travel. The fourth country is Liechtenstein which is located between Switzerland and Austria. Even this small country has no airport of its own and those who go here reach Liechtenstein by land travel to neighboring countries. The fifth country is Vatican City which has no airport but a heliport. The nearest airports are Rome Champagne and Rome Fiumicino.
