Getting there from the airport
It may be quicker and certainly cheaper to take the metro at the airport, as it is connected to the red line. From there, you can change to the yellow line at “Saldanha” station – “Odivelas” way. Then, you just have to exit the “Cidade Universitária” station. Faculdade de Ciências is at a 5m walking distance. Checkout this local area map (pdf), and walk towards waypoint number 10.
If you want to take a bus, look for number 783 towards Amoreiras (C. Comercial), and then hop-off at “Campo Grande” station. You can also look for the 731 towards Av. José Malhoa, and then hop-off at the “Cidade Universitária” station. Check out timetables and route plans here.
Probably, the easiest but most expensive way of going from the airport to the Conference is by taxi. Just tell the taxi driver to take you to the Faculty of Sciences at Campo Grande. There are two taxi stands within the perimeter of the airport, one at arrivals and the other at departures.
The fare on the taxi meter should read 3.25€ (daytime pick-up). Outside the city limits, city fares are charged per kilometer (1km=0,47€). 1,60€ is charged for the transportation of luggage or animals. Before taking a taxi, inquire about the fare. An additional 20% is charged for services on Saturdays, Sundays and holidays and for nighttime service from 9pm to 6am.
You can get more info and purchase a Taxi Voucher at the Tourism Information Counter in the airport’s Arrivals Hall.
A taxi can take up to 4 passengers.
