Type: Madrid Barajas or MAD, Barcelona or BCN and Malaga AGP, in destination area

Spain (Spanish: España) shares the Iberian Peninsula with Portugal. It has the second-largest number of UNESCO World Heritage Sites after Italy and the largest number of World Heritage Cities.

Spain is famous for its friendly inhabitants, relaxed lifestyle, its cuisine, vibrant nightlife, and world-famous folklore and festivities, and its history as the core of the vast Spanish Empire.

Spain’s flag carrier is Iberia, and its two other main airlines are Vueling and Air Europa. There are many airlines connecting from most European countries, Africa, the Americas and Asia. Virtually all European low cost carriers provide frequent services to Spain including: TUI Airways, EasyJet, Ryanair, Wizz Air and Jet2.com.

The busiest airports are Madrid–Barajas Airport, Barcelona El Prat, Palma de Mallorca and Malaga, followed by Seville, Valencia, Bilbao, Alicante and Santiago de Compostela.

If your final destination is in mainland Spain, Madrid Barajas (MAD), Barcelona (BCN) and Malaga (AGP) are your most likely ports of entry, as they have by far the highest amount of international flights. If your final destination is on one of the islands, you will most likely directly arrive at an airport on the island, without connecting through another Spanish airport.

By train
AVE in Spain (Spanish High Speed)
The train system in Spain is modern and reliable, most of the trains are brand new and the punctuality rate is one of the highest in Europe, the only problem is that not all the populated areas have a train station; sometimes small towns don’t have one, in those cases you need to take a bus. Another issue with the Spanish Rail network is that the lines are disposed in a radial way so almost all the lines head to Madrid. That’s why sometimes traveling from one city to another geographically close to it might take longer by train than by bus if they are not on the same line. Always check whether the bus or the train is more convenient. That being said the Spanish high speed rail system is more reliable than that of – say – Germany, because the gauge of traditional and high speed trains is different and thus high speed lines are only used by high speed passenger trains meaning fewer delays due to congested lines or technical problems. All lines that cross the border into France have either a break of gauge (thus making changing train or a lengthy gauge change necessary) or are high speed, thus making the high speed trains the vastly preferable option to cross the border. Trains between Barcelona and France are operated by both SNCF and RENFE and both sell tickets for any international train on that route.
