No, the iconic trams in Lisbon are not free; however, they can be very affordable if you use the right payment method. For a single journey purchased onboard the tram with cash, the price in 2026 is approximately €3.00, which is the most expensive way to travel. To save money, savvy travelers use the Viva Viagem or Navegante "zapping" card, which reduces the cost to about €1.50 to €1.70 per ride. If you have the Lisboa Card, travel on all trams—including the famous #28 and the modern #15 to Belém—is completely free for the duration of the card's validity. It is important to note that the historic yellow trams are often crowded with tourists, and pickpockets are known to operate on these routes, so keeping your ticket or card ready for validation is essential as inspectors frequently check for proof of payment. For those staying longer, a 24-hour public transport pass (€6.80) is the most cost-effective way to use the trams, metro, and buses interchangeably without worrying about individual fares for each leg of your journey.
