New to the site, discovering austria

Hi,
I've already been in Austria long time ago. Very soon I will go to Austria only for a short visit and would like to know if there are any multicultural photography groups organizing trekking trips and so on. I'm involved with graphics and like to take photographs of nature, cityscapes etc. I would appreciate helpful information.
Bye for now

Hi Melli,
I will go to Vienna and then Salzburg. I intend to take a lot of good city/landscape photos if possible:) I will appreciate every information.
thx
