Various discount cards are available, many covering a whole region or province. Some are free with an overnight stay (eg Neusiedler See Card in Burgenland and Zell am See Card in Salzburgerland); others cost a few euros (eg Salzkammergut Erlebnis Card). Others, such as the Kärnten Card in Carinthia and the Innsbruck Card, must be purchased, but yield more substantial benefits such as free entry to museums and attractions as well as discounts on public transport.
Senior Cards In some cases senior travellers will be able to get discount admission to sights, but local proof is often required. (It can’t hurt to ask and show proof of age, though.) The minimum qualifying age for Austrians is 60 or 65 for men and 60 for women.
Student & Youth Cards International Student Identity Cards (ISIC) and European Youth Card (Euro<26; check www.euro26.org for discounts) will get you discounts at most museums, galleries and theatres. Admission is generally a little higher than the price for children.
