Nothing wrong with Vorarlberg and it's hard to find an area in the Austrian Alps not good for hiking. So many well marked routes and mountain lifts. In general look at the valleys. North-South like The Zillertal, Stubaital, Ötztal, Pitztal, Raurisertal, Gasteinertal, Großarltal, etc. You might like Osttirol East-West like Virgental, Defereggental, Kaisertal (Kals am Großglockner). Other areas like Serfaus-Fiss-Ladis, the Zugspitze Arena and Ehrwald, around the Wilden Kaiser -Scheffau, Going and Ellmau, The area around Schladming-Dachstein - Ramsau am Dachstein. Seefeld in Tirol. Heiligenblut. Biosphärenpark Nockberge. Sorry not being much help and before long I'll name all of the Austrian Alps! My hiking days are slowly ending. A 6k steep hike 3 up and 3 down and a 14k relatively flat one was a challenge for me this year. People born in the Alps are like mountain goats. No fat people there. I'm tending to find smaller more secluded areas nowadays, finding a good place to stay and park myself. Limited public transportation there. I have my own car, so getting to these places is not difficult. I stayed in Lech, Gries (Ötzta), Hinterhornbach and just got back from the Lesachtal this year.
