Hello, these gas cartridges are really everywhere, in Asia shops, DIY stores, practically on every corner! For the first time you have to have a couple of them , but then , I am pretty sure, you will find supplies quickly! Have a good trip and stay healthy!

Good day! Dear man or woman or something! Why don't you ask the campsites themselves if they sell these cartridges? I bought them on the internet: http://www.deubaxxl.ch/
