Useful Information for Backpacking South America

Three: the Brazilian real, the Argentine peso and the Uruguayan peso. Cards and contactless are widely accepted in all three, and since Argentina lifted its currency controls in 2025, foreign cards there get a rate close to the cash rate, so paying by card is usually simplest.

Keep a little local cash in each country for small shops, snacks and tips, drawn from ATMs inside banks. If a card machine offers to charge you in pounds, choose the local currency.

This trip works in any season, with a different feel in each. December to March is summer: hot, humid and ideal for beaches, with Iguaçu Falls at its fullest, but also the busiest time. June to August is winter in the south, with mild days and chilly nights in Uruguay and Buenos Aires, so bring a warm layer.

Spring (September to November) and autumn (March to May) are the sweet spots for walking cities comfortably. Our Brazil weather guide has more on the Brazilian leg.

In Brazil, stick to filtered or bottled water. In Buenos Aires and most of Uruguay the tap water is treated and generally considered safe to drink, although it can taste of chlorine and anyone with a sensitive stomach may prefer bottled.

A refillable bottle, ideally with a filter, covers you across all three countries.

Most unlocked phones work in all three countries. Check your UK network's roaming charges first, as South America is usually outside roaming bundles. A regional travel eSIM covering all three, set up before you fly, is the simplest option.

Coverage is good in the cities and patchier on islands, around the falls and on long bus journeys. Most accommodation has Wi-Fi.

Tipping is not compulsory, but it is normal. In Brazil a 10% service charge is usually added to restaurant bills. In Argentina and Uruguay around 10% is customary in restaurants, and in Argentina it is often left in cash even if you pay the bill by card.

Guides, drivers and boat crews appreciate a small tip for good service. Your group leader can suggest sensible amounts.

Yes, with the usual big-city care. Petty theft is the main risk, particularly on busy beaches and streets in Rio, São Paulo and Buenos Aires, so keep your phone out of sight, carry only what you need and use taxis booked by app or through your accommodation at night.

Uruguay is one of the most relaxed countries in South America. Check the latest FCDO advice for Brazil, Argentina and Uruguay before you travel.

Speak to your GP or a travel clinic about 6–8 weeks before you travel, and check the advice for all three countries on TravelHealthPro, covering vaccines and avoiding mosquito bites.

Mention the Iguaçu Falls area at your appointment, as advice there can differ from the cities, and pack insect repellent.
