Driving in Portugal is highly recommended for travelers who want to explore beyond the major cities of Lisbon and Porto. It is the only practical way to reach the hidden beaches of the Algarve, the historic villages of the Alentejo, and the terraced vineyards of the Douro Valley. Portugal’s highway network (autoestradas) is excellent and well-maintained, though most are toll roads that use an electronic "Via Verde" system. However, driving within the historic centers of Lisbon or Porto is discouraged due to extremely narrow streets, limited parking, and confusing one-way systems; it is better to park on the outskirts and use the efficient public transit. In 2026, authorities have also increased road safety enforcement with more speed cameras and "Travel Without Rush" campaigns. If you choose to drive, be prepared for some aggressive local driving styles and the high cost of fuel. For a road trip across the stunning Portuguese countryside, a rental car provides unparalleled freedom and access to the country's most authentic and scenic landscapes that trains and buses simply cannot reach.
