My partner and I have purchased cheap return tickets flying in and out of Buenos Aires, Argentina 6 months apart.
We are planning on travelling south from Colombia to Ecuador, Peru, Bolivia, Chile and then fly out from BA.
What is the "best" way to get from Buenos Aires to Bogota to start our trip southwards? Flights are currently $850 AUD (about $700 USD) each direct, which is very expensive. Cost is not the only consideration, as long as we can gather some great experiences on the way - but we are travelling for 12 months in total, so the flights are a huge hit on the budget.
We are considering that we can fly from Rio (Brazil) to Manaus for $140 AUD (about $100 USD) each, so it may be worth going via Iguazu Falls and Brazil, then going overland to Bogota. The problem is that I'm Australian, so the Brazilian visa fee is about $200 AUD (my partner is Kiwi, so doesn't need a visa).
We are in no great hurry, we can take about 2 weeks.
The one other option we are considering is buying a car and driving it. I believe it's impossible to buy a car in Argentina and travel across borders, but it may be possible to purchase in Paraguay and travel up that way to Colombia.
Would love to hear some suggestions, especially from people who have travelled from BA to Bogota. I know there's no perfect answer, but we are just trying to weigh up the best option for us.
