The best and most efficient way to get from Lisbon to Sintra in 2026 is by train, operated by Comboios de Portugal (CP). Trains depart every 20 minutes from the Rossio Station in central Lisbon, which is the most convenient for tourists. The journey takes approximately 40 minutes and costs about €2.30 for a one-way ticket. You can use your "Navegante" or "Viva Viagem" card (the same one used for the Lisbon Metro) to pay for the fare. Alternatively, you can take a train from the Oriente or Sete Rios stations if you are staying in the northern or eastern parts of the city. It is highly advised not to drive to Sintra, as parking is extremely limited, the roads are narrow and winding, and much of the historic center is closed to non-resident vehicles. Once you arrive at the Sintra train station, you can take the 434 tourist bus, which loops between the station, the town center, the Moorish Castle, and the Pena Palace, saving you a very steep and exhausting uphill hike.
