Although there is a gay scene in Zurich it is hard to compare to other places as Switzerland is such a small country. Zurich is definitley the place to be although I hear Lausanne is has great night life also. I have been all over U.S. and Europe and Switzerland is my least favorite for gay life. I am in a relationship and 40 so I do not find myself going out much but if I were younger I would be going out in Zurich for sure. Good luck and welcome.
