Should I book accommodation in advance?

Only book your first week and any stays during peak season (Dec-Feb in Patagonia, Carnival in Brazil). The rest can be booked 1-3 days ahead using Hostelworld or local recommendations.

How much cash should I carry?

Carry $200-300 USD in small bills for border crossings and rural areas. Many places don't accept cards, and ATMs can be scarce in remote areas like Bolivian salt flats or Patagonian towns.

Is it safe to travel alone?

Yes, with standard precautions. Stick to established backpacker routes, stay in hostels, don't flash valuables, and trust your instincts. Solo travel is common and you'll meet other travelers constantly.

What if I get sick at altitude?

Arrive in high-altitude cities (La Paz, Cusco) a day early to acclimatize. Drink coca tea, avoid alcohol, and ascend gradually. Carry altitude sickness medication if you're sensitive. Descend immediately if symptoms worsen.

How to Plan a 3-Month Backpacking Route Through South America

Start with a rough north-to-south or south-to-north route hitting 6-8 countries, allowing 1-3 weeks per country depending on size. Book your first week's accommodation and onward flights as you go. Budget $1,500-2,500 per month including flights.

Choose your direction and anchor points. Pick either north-to-south (Colombia to Argentina) or south-to-north (Chile to Colombia). Book flights into one major hub (Lima, Bogotá, or Buenos Aires) and plan to fly out from the opposite end. This avoids expensive backtracking flights.
Map out 6-8 countries with time allocation. Allow 2-3 weeks for large countries (Brazil, Argentina, Peru), 1-2 weeks for medium countries (Colombia, Bolivia, Chile), and 1 week for smaller countries (Ecuador, Uruguay). Don't try to see everything—12 countries in 12 weeks means constant movement.
Research visa requirements and get them early. Brazil requires a visa for US citizens (apply 3 months ahead). Bolivia offers visa on arrival but bring passport photos and yellow fever certificate. Check if your route requires yellow fever vaccination—get it 10 days before travel.
Book your first week only. Reserve accommodation for your first 5-7 days and your international flights. Leave everything else flexible. You'll want to adjust timing based on weather, other travelers' recommendations, and your own pace preferences.
Plan around seasons and weather windows. Hit Patagonia during their summer (Dec-Mar), avoid Bolivia's altiplano during rainy season (Dec-Mar), and time Peru for dry season (May-Sep). Build your route around these fixed windows, then fill in flexible destinations.
Set up money access and budget tracking. Get a card with no foreign transaction fees. Notify your bank of travel dates. Set up a simple tracking system—many backpackers use a phone notes app to track daily spending by category.
