Hi! there are many fields in the northern region of Portugal , just next to porto airport you have Maia, Vilar de Luz (LPVL). Great place with a huge school..etc... great Snack-bar etc...
, Other great places for renting are: Viseu and Vila Real!
You can go to this page,
Aerodromos em Portugal wich is a map of portugal with all the airports, aerodromes and clic on any one of those fields, then it shows you ll the info on the field as well as an aerial photo of the rwy.
Have fun, it's great to fly in Portugal!
