Yes, you can get an Uber to Pena Palace in Sintra in 2026, but it is a "logistical gamble" that requires careful planning. Due to strict traffic regulations introduced to protect the historic hills, private vehicles are prohibited from the upper roads near the palace. Uber and other ride-hailing services like Bolt are technically allowed, but drivers often cancel or refuse trips to the palace because they fear getting stuck in the heavy tourist traffic or find the one-way loop unprofitable. If you do get a ride, it typically costs around €6 to €10 from the Sintra train station. However, for a 2026 visit, it is often more reliable to take the 434 tourist bus, which has priority access and a guaranteed schedule. If you insist on a private ride, a traditional taxi or a specialized Tuk-Tuk is often a better bet than an Uber, as those drivers are more accustomed to the specific mountain routes.
