So many places... so little snow pack...
I have been all over and would say go... but you state it looks like late July time and they will be out of snow. Just over Brenner Pass coming into Italy has soem KICK ASS boating. They are very low snowpack right now.
Slovakia and Austria just south of Brenner (Mayrhofen) have some great areas to creek as well.
The Upper Inn has huge volume runs that are year round even with the low snow pack.
Get it before the end of June if you are going to head over, not to mention cheaper as well that time of year before the tourist boom.
