Hello
I have only spent New Year in Buenos Aires, but any of the options you chose will be fine, because they are very beautiful cities three. Just keep in mind that Salta and Mendoza are generally warmer than that date Bariloche.
Greetings

Hi,
I am currently planning a trip to Argentina for a month over Christmas / New Year, and trying to decide where we spend Christmas / New Year. Currently looking at being in one of the following for Christmas or New Year:
Bariloche
Mendoza
Salta
Does anyone have any thoughts on the above, and if so can you recommenc somewhere to stay?
Cheers in advance.
