South America for travel money, four countries compared
Thinking about South America but not sure which country? Here is how Brazil, Argentina, Colombia and Ecuador compare on the money side, so you can pick with eyes open. Our read as the True Trip Costs desk, checked Jul 2026.
The short answer
Colombia is the easiest, best-value first trip.
Iconic beaches and Rio? Brazil. Wine and Buenos Aires? Argentina. The US dollar and the Galapagos? Ecuador.
| Country | Daily cost | Cash or card | Tipping | Taxis | Currency |
|---|---|---|---|---|---|
 Brazil | Cards and Pix | Service added | Some care | Real | |
 Argentina | Cash, bring USD | About 10% | Easy | Peso Argentine | |
 Colombia | Cards in cities | About 10% | Some care | Peso Colombian | |
 Ecuador | US dollars, small bills | About 10% | Take care | US dollar yes, USD |
Reading this. Daily cost is a rough 1 to 4 scale across these four (more dots, pricier day), the desk's own read rather than a precise figure. Taxi ease reflects each country's local picture: Easy is straightforward, Some care means a couple of things to watch, Take care means lean on apps and stay alert. Tap any country for the detail behind its row.
The honest headline
Good value across the board, but each has a money quirk
South America is one of the better-value regions we cover, with Colombia the cheapest and Brazil a little pricier. What varies is how you pay and what to watch. Brazil is card and Pix friendly; Argentina's exchange rates swing, so cash US dollars versus card can genuinely change your costs; Ecuador simply uses the US dollar, so there is nothing to convert; and Colombia leans on cash outside its cities. Tipping is a light habit at around 10%, often already added as a service charge. One practical note: it is Spanish everywhere except Brazil, which speaks Portuguese.
Which to pick
A verdict on each
Brazil
Beaches, Rio and Iguazu
The giant, and the icon: Rio, Iguazu Falls, the Amazon and endless coastline, enough for a whole trip on its own. It is the most card-friendly of the four, with Pix and cards everywhere, a 10% service charge usually stands in for tipping, and it runs a little pricier than its neighbors. Portuguese, not Spanish, sets it apart. Pick Brazil for the marquee sights and the beaches.

Buenos Aires, wine, Patagonia
Buenos Aires, world-class steak and wine, and Patagonia if you have the time. The money quirk to know: exchange rates swing, and how you pay, cash US dollars versus card, can change what you effectively spend, so check the current picture before you go. Tip around 10%, in cash. Pick Argentina for the food, the wine and the drama of the south.

Medellin, Cartagena, coffee
The best value on the continent, and an easy, welcoming introduction: Medellin, Cartagena and the Coffee Region are three different trips in one country. Cards work in the cities, cash beyond them, and you tip about 10%. Pick Colombia for variety and value, and the gentlest learning curve of the four.
The Colombia money guide →Ecuador
Quito, and the Galapagos
Small, and unusually easy for Americans, because it runs on the US dollar, so there is no currency to convert. Quito's colonial center is a highlight, and the Galapagos, if the budget stretches, is extraordinary. Carry small bills, tip about 10%, and lean on ride apps for taxis. Pick Ecuador for the dollar convenience, Quito and the wildlife.

- Tip about 10%, often already on the bill.
From the desk
If it were my trip
For South America I would fly into Sao Paulo or Rio de Janeiro, which usually have the best fares from the US, then work my way around. See Brazil beyond the beaches: Rio is iconic, but do not miss Iguazu Falls on the Argentine border, or the Amazon if you can. From there, Argentina for Buenos Aires, the food and the wine, with Patagonia if time allows. Continue to Colombia, one of the best values on the continent, where Medellin, Cartagena and the Coffee Region are three very different experiences. Finish in Ecuador, for Quito's beautiful colonial center and, if the budget stretches, the Galapagos, one of the great wildlife destinations on earth. With extra time I would strongly add Peru: Machu Picchu and the Sacred Valley are unforgettable, and Peru slots naturally into this route. It is a superb mix of cities, natural wonders, wildlife and some of the best food in the Americas, with little backtracking.
