Getting to Ushuaia and El Calafate

TIP
Negotiate. Prices can be negotiated. Also, if you are studying in Argentina, make sure to bring your student ID card, cause it will get you a very STEEP discount. All in all, we ended up paying about $280 for the round trip bus ticket.

It's a 48 HOUR trip. So, I cannot emphasize hard enough that you should consider going by plane.

By Plane
Plane can be expensive if you try to buy it directly. The prices advertised are for Argentineans, and foreigners are charged a lot more. However, there is a way to get a much cheaper flight, which will run you about $100 to $200 more than the bus option - and that is by buying a package.

TIP
The cheapest I found was through Despegar.com. The package that makes the most sense is the one getting to El Calafate, which is where the glaciers are at. From there, you can coordinate a bus ticket to Ushuaia which can run you about $70 round trip.

To get to Ushuaia, there is no direct route from El Calafate. You will have to stop at Rio Gallegos and board another bus to Ushuaia.
