The city of Zaragoza is located in Aragón, northeast Spain, at a similar distance (350 kms) from Madrid, Barcelona, Bilbao or Valencia (map). The city was built more than 2,000 years ago on the banks of the Ebro river and currently has over 650,000 inhabitants. The climate is called continental mediterranean, which means that it can get quite cold in the winter and then very warm in the summer, so it is a good idea to check the forecast before your trip.

Zaragoza by train

Perhaps the most convenient way to reach Zaragoza is flying to Madrid or Barcelona and then taking the AVE train to Zaragoza, operated by RENFE. These trains are comfortable and fast (~75min) and tickets can be cheaper if booked in advance (check the RENFE website):

  • From Madrid Atocha station, you can take either the AVE train to Barcelona or to Huesca (lines: "Ave Málaga / Sevilla - Madrid-Zaragoza-Camp de Tarragona - Barcelona" and "Ave Madrid-Zaragoza-Huesca").
  • From Barcelona Sants station, you must take the AVE train to Madrid (line: "Ave Málaga / Sevilla - Madrid-Zaragoza-Camp de Tarragona - Barcelona").

There are other (slower and cheaper) trains available that you can check online or at train stations, if you speak a little Spanish. All these trains arrive to Zaragoza Delicias station, which is both a train and a bus station. There are several local bus lines that can take you from Delicias station downtown, with from 1.35€ for a single trip: 34, Ci2 and also 51.

Flying to Zaragoza

Zaragoza's International Airport (Aeropuerto de Zaragoza, check AENA for all Spanish airports) is a small airport located nine kilometers away from the city center and it is reachable by taxi (<25€) and by bus (~2€, línea Aeropuerto-Zaragoza) from the city center and Delicias station. Only a few airlines operate regularly:

  • Ryanair (London, Brussels, Milan, Rome and Alicante)
  • Air Europa (from/to Canary and Balearic islands)

Zaragoza by coach/bus

An economic option is to reach Zaragoza from Madrid (Avenida de América station) or Barcelona Nord station by coach. This road trip usually takes just under 4hours and buses are quite frequent. Tickets are cheap (~25€ round-trip) and can be easily booked at the ALSA website. Some buses stop at Madrid airport (terminal 4), which can be convenient. Coaches arrive to the same Zaragoza Delicias station, from which you can take a taxi or several buses (51,34,Ci2).

Drive to Zaragoza Public transport in Zaragoza

A convenient way to move around the city is by taking local buses and trams. Please check the maps of routes and fares here and here. In addition, there is a network of bycicle stations spread around downtown, called BIZI, that registered users can take in one point and drop in another. It is possible to buy temporary passes.

Commuting from Zaragoza to Campus de Aula Dei

Estación Experimental de Aula Dei (EEAD) is part of the Campus de Aula Dei, in the Montañana district, some 12km north from downtown, across the river. There are mainly two ways to reach the campus:

By taxi the fare should be 18-20€ and it should take you around 25min from the area of the hotels recommended below. A little Spanish will definitely help since most drivers probably will not speak English. Normal taxis can take up to four people.

By bus (1€), there is a bus lines with frequencies of about 25min:

  • 28 (sentido Peñaflor, takes about 40 min from the first stop, just by the Puente de Hierro.

The bus stop is the first just after the one in front of the Gobierno de Aragón laboratory building (1). You must cross the road (2), pass through the main gate (3) and then walk towards the building sitting next to the roundabout, with stone stairs (4):

A bus journey from downtown to EEAD can take up to 50min, if you happen to miss the previous bus.

For the bicycle fans, there are a few routes to reach the campus ciclying from Zaragoza.


There are many hotels in Zaragoza, but we recommend a few options, all of them downtown and very well located in order to go to/from Delicias station (bus 34), to the airport, and to commute to Campus Aula Dei (bus 28). These hotels and the nearest bus stops are displayed in this map:

Meeting point

A suitable meeting point downtown that is walking-distance from all these accommodation options is by the statue of Caesar Augustus, next to the Roman walls (check the map):
