We would advise you to arrive on Sunday 18 June and to depart the following Saturday. The Symposium will kick off on Monday morning and concludes late on Friday night. Trieste airport has connections to Rome, Milan, Munich, Frankfurt, Valencia, and London Stansted.
For those arriving into Trieste–Friuli Venezia Giulia Airport (TRS), you can either take the bus (no. 51, costs €4.05) or the train into town. Taxis are expensive (about €60) and hard to find on a Sunday.
When you come through arrivals, there is a bus ticket machine to the right of the exit door. You buy the ticket there. The buses can be found to your right after you exit the airport building. Alternatively you can get the train. The station is a five-minute walk away. Again buy tickets in advance and convalidate your ticket before boarding. The train takes half an hour and costs €3.30. There’s one at 17 minutes past the hour. The bus takes more like an hour.
