Visas are straightforward for most Western passport holders. Citizens of the US, EU, UK, Canada, and Australia can enter most South American countries visa-free for 30 to 90 days. Brazil dropped its visa requirement for US citizens in recent years, making the continent almost entirely open. Bolivia still charges US citizens a reciprocity fee, and Suriname requires an e-visa for most nationalities. Always check current requirements before you go — things change. If you're planning a long overland trip, keep track of your allowed days in each country.
US dollars are accepted in Ecuador (it's the official currency) and widely useful as backup cash elsewhere. ATMs are plentiful in cities across the continent, but they often charge hefty fees and impose low withdrawal limits — Argentina is especially frustrating for this. In rural areas, small towns, and markets, cash is king. Always carry a stash of small bills in local currency. Credit cards work in hotels and restaurants in cities, but don't count on them outside urban areas. Moneychangers operate openly on the street in some countries; they're usually fine but count your bills carefully.
Spanish is the primary language in every country except Brazil (Portuguese), Guyana (English), Suriname (Dutch), and French Guiana (French). Even basic Spanish opens doors across the continent — people appreciate the effort. In tourist hubs, you'll find English speakers, but outside those zones, communication without some Spanish or Portuguese gets difficult fast. In the Andes, millions speak Quechua or Aymara alongside Spanish. In the Amazon, indigenous languages are still the daily tongue in many communities.
Safety varies enormously and painting the whole continent with one brush is a mistake. Chile, Uruguay, and Argentina are broadly safe for travelers. Colombia has transformed in the past two decades and is far safer than its reputation suggests, though certain neighborhoods and rural areas still require caution. Cities like Lima, Bogota, and Rio de Janeiro have the same street-smart rules as any big city: don't flash expensive gear, use registered taxis or ride apps, stay aware at night. Common scams include fake police asking to see your wallet, distraction theft, and express kidnappings in a few trouble spots. Use your judgment, ask locals where not to go, and don't let fear keep you from an extraordinary continent.
Mobile connectivity is good in cities and along major highways. Buying a local SIM card is cheap and easy in most countries — Colombia and Chile make it especially simple. Coverage drops off sharply in the Amazon, Patagonia, and remote Andean areas. Free Wi-Fi is available in most hostels, cafes, and restaurants. If you're planning to use your phone for navigation and translation (and you should), download offline maps and a language app before heading into rural areas.
Electricity runs on 220V in most of South America, with Colombia, Ecuador, and Venezuela on 110V. Plug types vary by country — Argentina uses a unique angled two-pin design, Brazil has its own three-pin standard, and the rest mostly use the US-style two-prong. Bring a universal adapter or pick one up locally. Most modern phone and laptop chargers handle dual voltage, but check before plugging in your hair dryer.
