The new train station is located just outside the arrivals hall on Terminal 3. From here you can go to the east (towards Malaga center) or west (towards Fuengirola). There is no way to get to Marbella by train, as this line ends in Fuengirola (you can get a bus from there).
The number 19 bus run by EMTSAM runs a service to Malaga Bus Station and the City Centre and costs 1 Euro. The bus runs from 6am - 12 midnight and departs from the arrivals section in both terminals 1 and 2.
Getting a taxi is the easiest way to move around the airport, but we advise booking your Malaga airport taxi in advance to avoid long airport queues and any possible scam.
