In the case that you were looking for night clubs at LUT, this post unfortunately does not contain the night clubs available in Lappeenranta. There are 25 clubs, 6 associations under the control and supervision of the Student Council,
LTKY. Among the 25 clubs, I am involved with MSAL (Muslim Students Association Lappeenranta) and SAHTI (Alcohol free club). The main idea of MSAL is to assist Muslim students about performing the religious activities. SAHTI is arranging some programs where there is no alcohol is involved.
Similarly, rest of the clubs have their own objectives.

Clubs may have their membership fees.
