The Lisboa Card offers several significant benefits for a trip to Sintra, but it does not cover everything. Most importantly, it includes free unlimited train travel between Lisbon and Sintra on the CP (Comboios de Portugal) lines, which usually depart from the Rossio or Oriente stations. In 2026, the card also provides free admission to certain local attractions like the Sintra Myths and Legends Interactive Centre and the National Palace of Mafra nearby. For the most famous monuments, such as the Pena Palace, the Castle of the Moors, and the Quinta da Regaleira, the card typically offers a 10% to 20% discount rather than free entry. While it saves you the cost of the commute and offers price reductions at the gate, you should still plan to pay for individual tickets to the major palaces. It is highly recommended to book these time-slotted tickets online in advance, as the Lisboa Card discount is often applied at the point of purchase or through specific kiosks, ensuring you don't miss out on the spectacular views and historic architecture of this UNESCO World Heritage site.
