In 2026, a one-way adult train ticket from Lisbon to Sintra costs €2.40, while the return trip is simply double that at €4.80. To travel, you must first purchase a reusable Navegante (formerly Viva Viagem) card for a one-time fee of €0.50. This card can be topped up at station kiosks or machines using cash or contactless cards. If you use the "Zapping" method—where you load a monetary balance onto the card in advance—the fare is slightly discounted to approximately €1.90 each way. The journey takes about 40 minutes and departs frequently from Rossio Station (most central) or Oriente and Entrecampos. There is no need to book these tickets in advance as they are regional trains and seats are not assigned. For seniors (65+) and children, the fare is reduced by 50% to €1.20. It is a highly reliable and scenic route, making it the most popular way for tourists to access the Pena Palace and other Sintra landmarks.
