The plane is the most convenient type of transport to get to Barcelona.
Considering that Spain is always a cloudless sky, then flights, as a rule, arrive and decrease on time.
At any point of the capital of Catalonia, you will easily reach the bus or train (Renfe), to which it is convenient to go with a luggage on the cart from the airport building. It seems to me, most comfortably use the train, because I caught on it to the city center, for example, to the station Sans, you can transfer to any subway line and get directly to the destination.
Tickets for travel should be purchased in advance before landing and it is better to immediately buy a subscription for 10 trips, which will be more economical. Such a ticket can be used for several people, compositing its corresponding number of times. This ticket will be valid and when transplanting a bus or other subway line within the boundaries of the same zone.
Considering that there are many lawsteps in Barcelona, for example, AIR BERLIN, then there is no point in your car for such a long distance.
It will be very expensive: only to cross France will cost, about, 120 euros - and it is one way. Add to this the cost of fuel, because even diesel is worth at least 1.15 euro / liter, then the price will turn out to be astronomical. In addition, on the way will have to stay on holidays in hotels.
If you are, you decide to go to Spain on your car, you should definitely buy a motorway, the so-called "green card". It is called that, because it is in fact green. Usually, the insurance policy covers only the civil liability of the driver, i.e. It works if you apply someone damage as a result of an accident. If you damage your car in your fault, then the insurance damage does not cover. Therefore, before buying it, think about what extra points would follow: it will be inexpensive, but can save you from unnecessary trouble, if something happens. I would contribute to the insurance item about free transportation of the car to a hundred in the event of a breakdown. If the car, for some reason, it breaks on the motorway, as the Spaniards call it - outopsthe, then it will be not cheap to deliver it to the settlement.
I think that it makes no sense to rent a car, for example, in Poland or in France, because It will be very expensive to pass it in Spain, so rent will have to execute for a long time. Considering that the car must be park somewhere and it is, it is hardly necessary to take it daily, then it is better to rent it right at Barcelona Airport.
The cost will be below 25%, if you are in advance, through the website of the company EUROPCAR pay for rent. You can pass the car in any branch of this company. The only one, preferably in the contract immediately indicate where it would be more convenient for you to pass the car, then it will be free.
Relatively so-called "international driver's license." If the name, surname, place of birth is duplicated in your driver's license, the categories of vehicles you can manage, then you do not need any "international rights". At least, we, over the past 15 years, took the car and in Spain, and other EU countries in their Ukrainian rights. At the same time, never had any questions anywhere. The only thing is very important that the limit on the credit card was at least 500 euros / day.
Public transport in Spain goes precisely the Swiss watches, however, according to some routes, the movement interval can be 30-40 minutes. Therefore, taking a booklet with a schedule of the route you need to the Bureau of Information, you can always navigate and sit back at a stop waiting.
