Skip Rental Cars for Historic Day Trips

Renting a vehicle might seem tempting for exploring scenic coastlines, but driving into medieval districts or taking a day trip to Sintra by car is a recipe for frustration. Portugal features extremely narrow historic streets, aggressive one-way systems, and strict resident-only parking zones enforced by heavy municipal fines.

For iconic spots like Sintra, avoid driving entirely; private vehicles are banned on key mountain roads leading to Pena Palace and the Moorish Castle. Instead, leverage Portugal's highly affordable and efficient CP train network from major transit hubs. When visiting rural regions like the Alentejo or the Douro Valley, rent your car only for those specific legs of the journey.
