Barbecuing in Austria

Usually you can buy it in supermarkets.

Ask your BnB.

but be aware of fire risk and any temporary or short term restrictions.

What do you expect to BBQ? And your sides?

Are you staying in Vienna or somewhere else?

Does your Airbnb come with a grill?

The answers to these questions will help me answer your questions.

I am hoping we will be able to grill some things behind our airbnb....Where is the best place to buy charcoal

Seems like your landlord should know; ask them?

We will be staying in the countryside in the Salzburg region and use a small portable grill, the airbnb owner has approved this. I can ask her about where to buy charcoal but I don't want to bother her with too many questions ahead of our stay. I figured this was a good forum to ask. Thank you for your replies!

Buchenholz/Beech wood. Preferably natural charcoal. Traditional in Austria and Germany.

Is BBQ-in in public parks actually forbidden? If they would try that in Switzerland they'd have a revolution on hand. I would have expected Austria to be similar.

In Vienna there are designated BBQ areas, typically along the Danube. If you grill in parks, you will be fined.
