Patagonia is all about massive blue glaciers calving into freezing water, jagged granite towers scraping the sky, and wind that makes you lean at a forty-degree angle. You want to give yourself plenty of time down there to actually hike and take it all in, which means you are looking at a serious travel investment.
A typical trip runs about $4500 once you factor in flights, gear, transport, and places to stay. Since booking airfare at least four months in advance is the bare minimum for snagging decent flight times down to South America, we need a solid plan to handle the upfront costs.
That 18-month window is a hard deadline, not free money, and any leftover balance when it ends will trigger regular interest charges on what you owe.
