Yes, you can take an Uber to Pena Palace in Sintra, but there are important "fine print" details to consider in 2026. While an Uber can take you from Lisbon or the Sintra city center directly to the palace gate, the road leading up the mountain (Estrada da Pena) is extremely narrow, winding, and often congested with tour buses and tuk-tuks. During peak tourist periods, local authorities sometimes restrict private vehicle access, which can include rideshare cars. If access is open, an Uber is a very convenient and relatively affordable way (approx. €7–€12 from Sintra station) to avoid the long, steep hike. However, if the road is closed to private cars, your Uber driver may have to drop you off at the bottom of the hill, requiring you to take the 434 tourist bus or a tuk-tuk for the final leg. For a "hassle-free" experience, it is often recommended to take the train to Sintra first and then use a local Uber or Bolt, as driving all the way from Lisbon can be expensive and prone to mountain traffic delays that increase the fare.
