Tipping
๐ฅPublic Transport
Uber and local app 99 are the safest and most practical options for tourists; Sรฃo Paulo and Rio have metro systems, while city buses are cheap but difficult to navigate.
โAvoid city buses in Rio de Janeiro and Sรฃo Paulo if you are carrying valuables โ pickpocketing and robbery on buses are common, particularly at night.
Full guide โ
Buenos Aires has an extensive Subte subway and Metrobus BRT network, both accessed with the rechargeable SUBE card.
โUber drivers in Buenos Aires sometimes ask passengers to sit in the front seat and avoid showing the phone screen at pickup to reduce confrontations with taxi drivers.
Full guide โ
Tourist Healthcare
Carry comprehensive travel insurance โ private hospitals in major cities are excellent but extremely expensive, and the free public system (SUS) involves long waits.
โDo not rely on the public SUS system for emergencies as a tourist โ without travel insurance covering private care, medical costs can be financially devastating.
Full guide โ
Private hospitals in Buenos Aires are excellent, but travel insurance with evacuation cover is essential โ especially in remote Patagonia.
โIf travelling to remote Patagonia or Tierra del Fuego, confirm your travel insurance explicitly covers medical evacuation โ standard policies sometimes exclude it.
Full guide โ
Local Laws
Cannabis is illegal, littering carries fines, LGBTQ+ rights are legally protected nationwide, and Carnival period carries specific public behavior tolerances that do not apply year-round.
โDrug laws in Brazil are enforced, and foreign nationals caught with cannabis or other illegal substances face arrest, detention, and potential deportation.
Full guide โ
Cannabis is decriminalized for personal use, abortion has been legal since 2020, and Argentina's complex currency regulations affect how tourists handle money.
โArgentina's economic laws around currency exchange are complex and change frequently โ exchanging money on the street (not at a reputable casa de cambio) exposes you to theft and counterfeit notes.

Emergency Numbers
Dress Code
Brazil is extremely casual in daily life, but beachwear must stay at the beach and religious sites require modest, covered clothing.
Full guide โ
Argentina has no strict dress codes, but Buenos Aires is a fashion-conscious city where smart-casual is the norm.
Full guide โ
Alcohol Rules
The legal drinking age is 18, alcohol is inexpensive and widely available, but drink-driving is strictly enforced with a near-zero tolerance BAC limit.
โBrazil's drink-driving enforcement is serious โ a BAC over 0.05% (or any measurable alcohol in some states) results in fines up to R$2,934, license suspension, and possible arrest. Use Uber or 99 after any drinking.
Full guide โ
The legal drinking age is 18, and Argentina has a rich wine culture โ Malbec from Mendoza is a point of national pride.
Full guide โ
Bargaining Culture
Bargaining is not standard in shops or restaurants but is accepted and expected at craft markets (feiras de artesanato) and flea markets.
Full guide โ
Prices are generally fixed in shops, but some flexibility exists at artisan markets and flea markets like San Telmo.
Full guide โ
Photography Rules
Photography is generally unrestricted in public spaces, but avoid photographing in favelas unless on an organized tour, and always ask permission before photographing indigenous peoples.
โDisplaying expensive camera equipment openly in crowded urban areas โ especially beaches, bus stations, and street markets โ makes you a target for theft. Keep gear secure and be discreet.
Full guide โ
Photography is generally unrestricted in Argentina; avoid photographing military and police installations.
โPhotographing military installations, border crossings, or police checkpoints can result in detention and equipment confiscation.
Full guide โ
Sunday & Holiday Hours
Shopping malls open seven days a week, banks are closed on weekends, and Carnival (February or March) shuts down most of the country for approximately five days.
โTraveling to Brazil during Carnival unprepared means facing extreme price gouging, fully booked accommodation, and chaotic transport โ plan and book far ahead or avoid peak Carnival cities if you prefer normal tourism.
Full guide โ
Major cities operate largely normally on Sundays, but national holidays cause widespread closures across Argentina.
Full guide โ
Taxi & Rideshare
๐ฅUse Uber or local app 99 rather than hailing street taxis, especially in Rio de Janeiro and Sรฃo Paulo where unofficial taxis carry real safety risks.
โNever hail street taxis in Rio de Janeiro or Sรฃo Paulo โ unofficial taxis ('pirate taxis') are linked to robberies and express kidnappings. Always use Uber, 99, or hotel-arranged radio taxis.
Full guide โ
Metered black-and-yellow taxis are reliable in Buenos Aires, and Uber operates well despite ongoing legal tension with taxi unions.
โAvoid accepting rides from unlicensed drivers who approach you inside airports or bus terminals โ use only official ranks or pre-booked apps.
Full guide โ
Water Safety
๐ฅDrink bottled or filtered water everywhere in Brazil โ tap water is technically treated in major cities but most locals and all tourists should avoid drinking it directly.
Full guide โ
Tap water is safe to drink in Buenos Aires and most major cities, and Patagonia's glacier-fed tap water is exceptionally pure.
Full guide โ
ATMs & Cash
Use ATMs inside shopping malls or banks during daylight hours โ Bradesco, Banco do Brasil, and Caixa are most reliable for foreign cards, and Pix digital payments are now ubiquitous.
โCard skimming at standalone ATMs (especially on streets) is a real risk in Brazil โ always cover the keypad when entering your PIN and check the card reader for tampering before inserting your card.
Full guide โ
Argentina's currency situation is critical โ withdrawing from ATMs at the official rate loses significant value, so carry USD or EUR to exchange at legal casas de cambio for the far better blue rate.
โNever exchange money with strangers on the street ('cambio, cambio' touts) โ counterfeit notes and short-changing are common risks; always use a reputable, fixed-premises casa de cambio.
Full guide โ
SIM Card & Internet
๐ฅBuy a prepaid SIM from Claro, TIM, or Vivo at the airport or a phone shop โ bring your passport as it is legally required for SIM registration.
Full guide โ
Claro, Movistar, and Personal sell prepaid SIMs at airports and phone shops; coverage is good in cities but patchy in Patagonia.
โConnectivity in remote Patagonia and Tierra del Fuego can be essentially non-existent โ download everything you need offline and inform someone of your itinerary before heading into the wilderness.
Full guide โ
Electricity & Plugs
๐ฅBrazil uses Type N plugs (two round pins plus a grounding pin) as its national standard, but voltage varies by city โ Sรฃo Paulo and Rio are 127V while many other cities are 220V.
โBrazil's split voltage system (127V vs 220V by city) is a genuine risk to electronics โ plugging a 127V-only device into a 220V socket without a transformer will permanently damage or destroy it.
Full guide โ
Argentina uses a unique Type I plug (three flat pins in a triangle shape) at 220V/50Hz โ most visitors need a specific adapter.
โPlugging a 110V-only device (some US hairdryers, older appliances) directly into an Argentine socket without a voltage converter will destroy the device and may cause a fire.

Scams to Avoid
Key scams to watch for include beach theft (arrastรฃo group robberies), distraction pickpockets, express kidnappings in cities, and people posing as police officers.
โExpress kidnappings โ being taken to multiple ATMs to withdraw money โ occur in Brazilian cities, particularly at night in isolated areas. Stick to busy, well-lit areas after dark and always use rideshare apps rather than walking to find a taxi.
Full guide โ
Watch out for the 'mustard' distraction scam, fake police officers, and street money changers offering counterfeit notes.
โExpress kidnapping (secuestro exprรฉs) โ being forced to an ATM to withdraw cash โ occurs rarely but does exist; avoid displaying expensive jewellery, cameras, or phones in busy or unfamiliar areas at night.
Full guide โ
Crime & Safety
Brazil has real and serious crime in major cities โ stay alert, avoid favelas without organized tours, and take specific precautions on Rio's beaches and in city centers after dark.
โRobbery at gunpoint (assalto) does happen in tourist areas of Rio and Sรฃo Paulo. Never resist โ hand over valuables immediately. The standard local advice is 'entregue tudo' (hand everything over) and report it afterward.
Full guide โ
Buenos Aires is generally safe in tourist areas, but pickpocketing is common in crowded spots and certain neighbourhoods like La Boca should be treated with caution.
โPetty theft and bag-snatching spike in crowded areas like the Retiro bus terminal and along Florida Street โ keep bags in front of your body and avoid displaying expensive electronics.

Cultural Etiquette
Brazilians are warm, physically affectionate, and time-flexible โ greet with cheek kisses, embrace the relaxed pace, and understand that football (soccer) is a near-religious passion.
Full guide โ
Greet with a single kiss on the cheek (even between men in casual settings), accept mate if offered, and prepare for very late meal times.
Full guide โ
Language Basics
Brazilians speak PORTUGUESE โ not Spanish โ and they are distinct enough that Spanish speakers cannot reliably communicate without effort; translation apps are essential outside tourist hubs.
Full guide โ
Argentine Spanish (Rioplatense) uses 'vos' instead of 'tรบ' and has a distinctive Italian-influenced accent unlike other Spanish-speaking countries.
Full guide โ
Beach & Swimming
Brazil's beaches are world-famous but rip currents (correntes) are a genuine danger โ always swim at flagged beaches, never swim alone, and watch for seasonal jellyfish.
โRip currents kill dozens of swimmers on Brazilian beaches every year โ always check the flag system, swim near lifeguard posts, and never swim at unflagged or unpatrolled beaches.
Full guide โ
Mar del Plata is Argentina's main beach resort, packed in JanuaryโFebruary; the Atlantic coast water is cold, and Patagonia's coastline is dramatic but frigid.
โRip currents and strong undertow are present on exposed Atlantic beaches; swim only in patrolled areas and heed red or yellow warning flags.

Driving Rules
Drive on the right, an international driving license is valid, but avoid driving at night in unfamiliar areas and be prepared for chaotic urban traffic and highly variable road conditions.
โNever drive at night on isolated highways or in unfamiliar rural areas of Brazil โ the risk of vehicle robbery, cattle on roads, and poor road conditions make night driving genuinely dangerous outside well-traveled routes.
Full guide โ
Drive on the right; an international driving licence is valid; fill up whenever you can in Patagonia where petrol stations are sparse.
โOn Patagonian gravel roads, loose stones thrown by passing vehicles can crack windscreens โ maintain a large following distance and check whether your rental insurance covers windscreen damage.
Full guide โ
Restaurants & Food
Brazil's food scene is extraordinary โ from churrascaria BBQ and feijoada to street snacks like coxinha and pastel โ eat at local boteco bars and kilo restaurants for the best value.
Full guide โ
Asado (Argentine BBQ) is the cultural institution, dinner starts at 9โ11pm, and dulce de leche appears on almost everything.
Full guide โ
Religious Site Etiquette
Brazil is predominantly Catholic with a rich Afro-Brazilian religious tradition โ cover shoulders and knees for all religious sites, and seek explicit permission before entering or photographing Candomblรฉ and Umbanda spaces.
โNever enter a Candomblรฉ or Umbanda terreiro uninvited or without explicit permission โ these are active sacred spaces for practicing communities, and unauthorized entry is disrespectful and unwelcome.
Full guide โ
Argentina is predominantly Catholic with significant Jewish and small Muslim communities; modest dress is appreciated at all religious sites.

Weather & Best Time
Rio and Sรฃo Paulo are best AprilโJune and AugustโOctober; the Amazon's dry season runs JuneโNovember; the Northeast is drier and sunny almost year-round; Carnival falls in February or March.
Full guide โ
Argentina's huge size means dramatically varied climates โ Buenos Aires is best in spring (SeptemberโNovember) and autumn (MarchโMay), while Patagonia peaks in DecemberโFebruary.
โPatagonian weather is famously unpredictable and can change from sunshine to snow in minutes โ always carry waterproofs and extra layers regardless of the forecast.

Money-Saving Tips
Eat prato feito (PF) lunches for R$15โ30, use kilo restaurants, take city buses instead of Uber, and enjoy Brazil's free world-class beaches to dramatically cut daily costs.
Full guide โ
Argentina's weak peso makes it extraordinary value for USD or EUR holders โ wine, steak, and accommodation are all remarkably affordable if you exchange at the blue rate.
