A one-way train ticket from Lisbon (departing from Rossio, Oriente, or Entrecampos stations) to Sintra costs €2.30 as of 2026. If you do not already have a reusable "Navegante" (formerly Viva Viagem) magnetic card, you will need to pay an additional €0.50 for the card itself, bringing your initial total to €2.80. This card can be topped up for your return journey or used for the Lisbon metro and buses. For tourists planning a full day of sightseeing, the "Train & Bus" daily pass is often a better value at approximately €15.00, as it includes the train fare plus unlimited use of the Scotturb buses in Sintra, which take you up the steep hills to the Pena Palace and the Moorish Castle. Tickets can be purchased at station windows or automated kiosks, which have English language options.
