Fun in Gent
Overpoort
Situated right in the middle of all university campusses, the overpoort is the main place for going out. The whole street is filled with pubs and fastfood restaurants (and the typically Belgian 'frituren'!). There's also a bowling alley, a couple of halls where the different student unions occasionally hold a Cantus (try to attend this at least once while in Ghent!) and much more.
Other clubs
Many other clubs and pubs are spread all throughout the city, some notable ones: Kompass Klub, Charlatan (and the rest of the old city centre), de Karper, de Omgekeerde Wereld, Defoo, ...

Student Unions
Almost every field of study at the university has its own student union. These host parties and activities (almost) weekly, and are usually also the first acces point for study assistance and the distribution of textbooks. Aside from the unions connected to the faculties and the university (of which VTK and maybe WiNA will be the most important to you), there are also loads of other unions, sometimes connected to a certain Flemish region or just not connected to anything else at all and made purely for fun (shoutout to De Parkwacht xx).
