Tap a contactless bank card: EUR 1.92, valid across the network — the cheapest option if you arrive with nothing. A navegante occasional card (EUR 0.50) plus a single ticket (EUR 1.90) costs EUR 2.40 instead. Zapping is cheapest per journey at EUR 1.72, but needs the card and a EUR 3 minimum top-up.
Luggage. No stated limit. Note that Carris caps luggage on city buses at 55x40x20 cm; the metro does not.
Hours. The whole network runs 06:30 to 01:00 every day including weekends and public holidays, the closing time being when the last train leaves each line's terminus. There is no extended night service on the red line, so a landing after 01:00 has no metro.
