Inland flights in Portugal are relatively expensive.So,owing to extent and favourable transfer „on the earth“, it is worth to use this way of transport only, in case when you have lack of time. The towns of Lisbon, Porto and Faro are connected daily. Moreover, the students have a pretension for a reduction, provided they present necessary documents.
Local bus lines could be divided into two different types: expressos (offer comfort, quick and direct connection between big towns) and carrieras (they are more slow and make a stop even in small communities).
State Railway Company Caminhos de Ferro Portugueses offers three types of trains: rapido or internacionale (IC), interregional (IR) and regional (R).
Attention: the tickets for the first two types could cost twice so much as for standard regional train. Anyway, if you have the intention to travel like this, it is worth to reserve the tickets, as some lines could be „sold out-blocked“ many weeks ahead. On the other hand, the pensioners and students could ask for granting reduction.
Nearly in any great town you meet the companies, offering „Rent a Car“. For driving, you need your driving licence, valid for one year at least, and you have to be older than 23 years of age. The drive in towns is rather hectic, on the other hand, the drive in the country is rather comforable, becouse you meet few cars there.
