Load a Navegante (or Viva Viagem) transit card with Zapping credit instead of buying single tickets. A card journey costs €1.66 versus €3.10 for an onboard tram ticket — and the card works across all four metro lines, buses, trams, funiculars, and trains to Sintra and Cascais. Lisboa Card holders travel free on all these networks for 24, 48, or 72 hours and get free or discounted entry to 51+ attractions. Ride Tram 28 before 9 AM or after 7 PM to get a seat and avoid peak pickpocket risk. Board at the Martim Moniz or Campo de Ourique terminus rather than a mid-route stop. For faster cross-city travel, use the metro — four color-coded lines run 6:30 AM to 1 AM daily.
