In reply to Tony Holdsworth:
There is little bouldering to be had in the Wilderkaiser (Kaisergebirge). There are occasional boulders to be found high up in the mountians but I'd personally not bother with the effort of going up there to boulder. A lot of locals just 'boulder' out the start of the sport routes there-about.
There is a couple of places south of Salzburg, both reasonable -

In the absence of bouldering...there is stacks of other things to do....sport climbing, scrambling, mountain biking, high alps.......My family is local to the area. If you want a full run-down send me mail and I'll send you my number. Call me & I'll tell you what you need to know.
