It seems difficult to find buses directly from BA to Cordoba (online anyway)
What is a good way of getting there?
Should I be looking at buses stopping at another destination on the way?
I went to Cordoba by bus but was coming from Uruguay so my route went through Santa Fe, but there would most certainly be direct buses between BA and Cordoba. http://www.omnilineas.com/argentina/bus/retiro/cordoba/ has some details. It Takes 10-11 hours, so I highly recommend getting a bus/seat that is comfy and may even recline; it's worth the price in my view.
I found the best way to get the full picture of who goes where and when was to go to the bus terminal a day or two before. Te terminal in BA is Retiro-huge bus terminal by the train station. I was surprised to learn of how many routes and companies offered services to places that I could not find info for online.

The advice to visit the terminal is good. There are dozens of bus companies that operate out of Bs As. We recently bused from Mendoza to San Martin de los Andes [SMDLA] (near Bariloche) on Andesmar. then we bused from there to Bs As on Via Bariloche. I strongly recommend the latter over the former. We took a 'super-cama' on the Via Bariloche bus and it was very comfortable; it was a 20 trip. The food was better too.Both of these lines should go to Cordoba. That's a shorter trip so you'll have to decide if the full flat bed super-cama is worth the few extra bucks to you.
If you go to the Retiro terminal, ask if you can check out the buses before you buy. Via Bariloche let us do this in SMDLA and it was nice to know in advance how comfortable it was going to be.
The omnilineas link in the other response is a good source. I sent them an email about my pending trip and got an almost immediate response; they even made a reservation for me. My plans changed so I ended up not needing it, but I was impressed at the thoroughness of their response.
We had traveled around Argentina both by bus and plane. if I go again, I'll always check teh buses first. Enjoy! over 7 years ago
