I was in Montreal last week gathering French books and newspapers. I also explored several neighborhoods to get a feel for the local culture. I was wondering how to say "I am a tourist." because I wanted to make it clear that I was not a native anglophone.

I'm not certain if I should say "Je suis un touriste." or "Je suis touriste." I know you leave out the indefinite article if you are indicating your profession but a tourist is not a profession. I've searched the Internet but did not find a clear answer.
