Little known in broader public, but a highlight event amongst insiders are the annual conference series of the European Forum in the most pittoresque village of Alpbach in the Austrian Alps (see http://www.alpbach.org/en/forum-2013/ ).
High ranking representatives of public life such as EU Commission President Baroso, or, in this year 2013 again, UN Secretary General Ban Ki-Moon are frequent guests at this major think tank event.
