Getting to Girona Airport by Taxi can be very expensive.
It is very important to check Bus Prices and Timetables before resorting to Taxi's, you have been warned. In and around the Airport you will see many Taxi's parked close by, what they dont tell you is that the Train Line and Bus Line is also very close by. The Bus Line is directly outside the Airport door, with posters and timetables of exactly where it goes and what time it gets there.
If you are not staying close to the airport, then please do take in mind the high prices that Taxi's charge.
