Depending on your Sintra itinerary, the Sintra Green Card could be a good option for you. This discount tourist card includes public transportation and entry to some of Sintra's main attractions. There are two options, and they are worth the price if you plan to do everything that's included with them.

The Sintra Green Card (often evaluated alongside the broader Lisboa Card) is generally considered a fantastic value for travelers who plan to visit Sintra's "Big Three" sites—the Pena Palace, the National Palace, and the Quinta da Regaleira—within a single day. In 2026, entry fees for these individual landmarks have reached between €15 and €20 each. The card typically bundles transportation on the CP Urban Trains (the Sintra line from Lisbon) and the Scotturb bus 434, which is the essential loop connecting the train station to the hillside palaces. If you are a solo traveler or couple planning to see at least two major monuments and use the tourist bus twice, the card pays for itself. However, it is less "worth it" if you prefer hiking up the steep hills or if you only plan to see one palace before heading back, as the individual train tickets are relatively inexpensive.
