Ok, so first thing off, one of you asked about native Portuguese martial arts, there is just one native martial art:
Jogo do pau - Wikipedia
However this is like sword fighting and I might not have a stick with me at all times. (Literally this is the only native martial art in Portugal.)
Second I live nearby big cities, I have a lot of school a google search of distance. Just within a 15 minute walk I have a gym that teaches krav maga and a karate dojo. If I catch a bus to the next town, the local football club offers judo classes (competitive). But like I said I hated judo, in judo if you're down you can't support yourself with your hands and then kick with the legs, whenever I fell down i put my hands backward as instinct and I just hate let myself go and just plain hit my head in the tatami.
