Dresden may not have the most interesting LGBT night life in Germany, but there are still places you could go. The most beloved bars are Boys on Alaunstrasse and Queens on Goerlitzer strasse. There are no gay clubs/discos in town, but once a month two bigger events take place. The firtst is Think Pink, in the Industrial area, which is popular for clubbing events in the city. Think Pink is quite expensive, but frequented. The other one is Disco Wo Anders  in Baerenzwinger, on the Old City side of Dresden. It is a student party, so the public is mainly younger nad it is very cheap, since it was made for a tight student budget. Nevertheless, the music is very nice 80s/90s/charts and the public is mixed.
There is a CSD/Pride Parade every first weekend of June in Dresden too.
