Travelers can use trains or buses to navigate Portugal efficiently. The ticket cost for trains ranges from $10-$30, depending on the distance traveled. Buses are typically less expensive and can cost as little as $5 for short trips. Car rentals are also an option, with prices starting at about $40 a day. Some cities, such as Lisbon and Porto, have excellent public transportation systems, including trams and subways, which are both convenient and inexpensive.
If you have extra time, consider adding a day trip to the Algarve for stunning beaches and coastal views. Alternatively, if you have a shorter stay, consider cutting out a day trip or shortening your stay in Porto, Coimbra, or Évora. It's also important to note that the wintertime can be rainy and cool in Portugal, while summers are hot and can be crowded. Travelers should plan accordingly, and be sure to bring comfortable walking shoes as the country is full of flat cobblestones and hills.
