In May 2022 we are renting a car in Porto and driving through the valley to Pinhao. From Pinhao we want to head back south to Estremoz, Evora and eventually Algarve. Is the route A25 and IP2 a save option? Is it worth of driving to see the east side of Portugal? Or should we change our route possibly going back to Porto, Coimbra to Evora?
