From the Mediterranean coast to the Iberian Plateau, the landscape transforms dramatically. Near Zaragoza, the Ebro valley offers flat agricultural plains. The A-23 passes through the Sierra de Albarracín, a region of pine forests and red sandstone formations. As you cross into Portugal, the Serra da Estrela looms with its granite peaks and glacial valleys.

• Natural attractions: Pico do Arieiro (viewpoint), Serra da Estrela Natural Park, the Mondego River valley.
• Local commerce: Stop in Teruel for jamón serrano and truffles; in Guarda, try queijo da serra (cheese). In Viseu, visit the mercado municipal for local crafts.
• UNESCO sites: The Roman aqueduct of Tarragona (near start) and the historic center of Salamanca (on route) are UNESCO-listed. Viseu’s cathedral and Grão Vasco museum are notable.

Climate: Tarragona has a Mediterranean climate (mild winters, hot summers). As you move inland, temperatures become more continental: cold winters and hot summers. The Serra da Estrela can have snow from December to March. The best time to drive is spring (April–May) or autumn (September–October) for pleasant temperatures and fewer tourists.

Road quality is excellent throughout; Spanish and Portuguese highways are well-maintained. However, some sections of the A-23 have sharp curves and elevation changes. Radar traps are common; use cruise control. In Portugal, speed cameras are often on bridges.

• Child suitability: Many rest areas have playgrounds. Zoo de Barcelona and Aqualeon (between Tarragona and Zaragoza) are great for kids. In Portugal, the Serra da Estrela has pony rides and nature trails.
• Pet-friendly framework: Most Spanish and Portuguese hotels accept pets; check ahead. Rest stops often have grassy areas for dogs. Carry water and a bowl.
