Andorra Passport and Visas Information
Due mainly to the mountainous nature of Andorra, there is only one road entering Andorra from France, and only one widely-used road entering Andorra from Spain. Almost all entry into the country happens at one of these two points.
Visitors from outside the EU should note that Andorra is not a Schengen member, and exiting France or Spain into Andorra will (theoretically) terminate a single-entry visa. In practice, though, immigration does not enforce this.
