The only way you can enter the territory of Andorra is by using the car road – Andorra doesn't have an airport, nor a railway. You can cross the border of Andorra from France or Spain – there are no more than two or three widely-used roads, because of the mountainous nature of the country. There are various international bus routes which include Andorra, and most of them are Spanish. You can also go to the country by using your own car, a rented car or a taxi. Keep in mind that Andorra is not a part of the European Union, so you’ll need a visa to enter the country.
