|Barcelona to Girona|
The driving route from Barcelona to Girona is 100km and if there isn't too much traffic, it shouldn't take more than 1 hour and 20 minutes by motorway. The first stretch costs about €1.25. After that you'll pass through a short stretch in Girona that will be 90 cents.
The A7 motorway is predominantly a toll motorway. Once you've left Barcelona and you are on the motorway, you will eventually see signs that tell you that in 1000m you will have to pay. This is 'peatge' in Catalan and 'peaje' in Castiliano Spanish.
You'll see several pay booths to choose from. I advise you to go to the one that says 'manual'. The others are either for use with your credit card (and they don't always accept foreign cards or debit cards) or motorists who have a special permit. At the manual booth you will have to stop and pay the attendant through the window. The price will be displayed in front of you on a screen. If you want a receipt, ask for a 'ticket'.
The barrier will lift and you can pass through. Keep your eyes open around the booths as drivers tend to cut across the traffic to get to the lane they want.
On some stretches of the motorway, nearer to Girona, you will come to a toll stop point where you don't have to pay. You still have to stop at the barrier, but this time you have to take a ticket. The ticket will automatically eject from the machine next to the barrier when you pull up there. Keep the ticket until you come to the 'peaje' or 'peatge' point on the motorway where you have to pay. Give the ticket to the attendant, and they will then tell you how much to pay.
From Barcelona the A7 motorway is signposted. The 'A7' is usually in blue. Take the A7 in the direction of Girona.
To help you plan your route, try the online route planner by Michelin. I found it quite useful for telling me how many kilometres I had to travel along the motorway, and it also gives you the price of the tolls.
When you get nearer Girona, first you'll pass the airport. Keep going if you want the centre and exit for Girona Sur (Girona South). This is exit 7. (salida or sortida 7) Follow signs for Girona Centre. You will pass over 2 roundabouts. The signs are not always visible due to overhanging trees, but there is more than one way to get to the centre from these roundabouts, so even if you are not sure you have taken the correct road off the roundabout, keep going to the next one and there will be more signs there.
The driving route from Barcelona to Girona is an easy route as it is mostly motorway. There are toll charges that apply, but they are minimal. The journey should only take about one hour and 20 minutes.
