In reply to martin.p65:
There are 3 campsites in Imst, two of which are near to the Kletterhalle/climbing wall. I lived in Landeck and there is the
Starkenbach nearby with lots of easier climbs, and
Gotterwandl nearer to Imst with harder stuff. Looks like there are other Klettergartens nearby too which I didn't visit:

I used the bus and trains a lot to travel between Landeck and Imst, although the Imst station is a bit out of the way of the centre if you plan to walk to it. Buses were fine though.
Email me for more general info if you have any questions about the area!
