In reply to Tom Redwood:
The Oberreid Eispark was set up last year for the first time, there are probably about 10 lines there, some of about grade 4 on the left, but the main section looks to be pitches of about 35m at 5 or 6. Park as for the route Daumenschrauber in the oetztal section of the climbers paradise app. I've got some photos from last year somewhere that I'll try and put on.
The most reliable venues seem to be Ochsengarten in oetztal, and the Kitzgarten and Taschactschluct gorges in Pitztal. There are some details on the UKC logs.
The Osttirol Eispark has it's own site with topos etc on it, I think you may have to book a spot in advance when it's busy as they try to limit the numbers.
Ps. The Climbers paradise website has some useful location maps on it under the galerie sections for the routes, that aren't on the app.
