Alternative Portugal - are, first of all, small villages of 600-800 inhabitants. You can hardly even see them on a world map, but that's where all the local flavor lies. Secondly, they are indescribable natural wonders, where there are no crowds of tourists and where you can quietly enjoy the scenery. Thirdly, it is a chance to see "live" Portugal with all its pros and cons.
Such a trip is better to combine and mix with big tourist locations and thus explore the country region by region: north, northern border with Spain. The center, the south coast, the eastern border with Spain, etc. The best way to travel around these places is to rent a car, the prices for rent in Portugal are low (promotional offers - from €5 per day).
For the night you can stay in small hotels (prices from about €20 per night for two people), rent a room from locals or stay in albergues (shelters for pilgrims along the Camino de Santiago).
