The intercambio circuit is your social infrastructure
Language exchange evenings run most Tuesdays and Wednesdays during university term at a rotating set of bars — ask at the international students office at the Universidad de Granada or check the noticeboards at the Faculty of Translation near Plaza de la Trinidad. The format is structured enough to start conversations but informal enough to turn into friendships. Most of the long-stay foreigners in Granada will tell you the intercambio circuit is where they built their first social connections. The Tandem app works for one-on-one arrangements; the bar evenings are better if you want to meet a wider range of people quickly.
