Working out which travel card you need to use Lisbon’s many forms of public transport can prove more complicated than it should be. If you have a Lisbon card, your travel costs are covered. If not, you need to think about how many trips you are likely to be doing each day and which forms of transport that will involve.
If you’re travelling within the city and plan to make more than five single trips per day using only buses and the metro, a 6 euro daily pass is your best option. If you intend to do less journeys or use more forms of transport on any given day, Zapping is the way to go.
