I apologize if this has been already discussed. I would like to travel from Buenos Aires to Catamarca by bus. I know there are some "fancy" night buses and cannot find a website or names. Anybody has tried that service?

Here is a list of the long distance bus companies that go to Catamarca:

Cacorba
Chevallier
Empresa Gutiérrez
Sierras de Córdoba
Tac

And here is a website where the companies are listed with telephone numbers. Im afraid that most dont have websites.

Eso era exactamente lo que andaba buscando.
The flights to Catamarca are US$ 400 so I think I will be taking the bus.
Thanks
