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

Start with Colombia or Ecuador, work south through Peru and Bolivia, then choose between Chile/Argentina or Brazil/Uruguay. Budget $2,000-3,500 total. Book flights and first few nights only—flexibility is key for weather, festivals, and connections you'll make.

  1. Choose your entry and exit points. Fly into Bogotá or Quito (cheapest from North America/Europe) or Lima if focusing on Peru first. Plan to fly out from Buenos Aires, Santiago, or São Paulo. Round-trip tickets are often cheaper than one-way, even if you don't use the return.
  2. Map your basic route direction. Go north to south to follow the dry season. Start April-September in Colombia/Ecuador, hit Peru/Bolivia by May-August, reach Patagonia by November-March. Or reverse it: start in Argentina/Chile October-March, work north to finish in Colombia during their dry season.
  3. Pick your must-see anchor points. Choose 4-6 major stops and plan 1-2 weeks each: Cartagena, Machu Picchu, Salar de Uyuni, Rio, Buenos Aires, Torres del Paine. These become your booking deadlines and budget your time backward from them.
  4. Plan around weather windows. Dry season for hiking: Peru/Bolivia (May-September), Patagonia (November-March), Amazon (June-November). Carnival is February. Book Machu Picchu permits 4 months ahead. Torres del Paine books up 6 months ahead for peak season.
  5. Book minimally upfront. Book only: international flights, first 3-4 nights accommodation, and any advance-booking activities (Machu Picchu, Torres del Paine if going peak season). Leave everything else flexible—you'll change your mind based on weather, people you meet, and places you love.
  6. Set up your money system. Get a fee-free debit card (Charles Schwab, Capital One 360). Notify your bank of travel dates. Carry $500 USD cash for emergencies and border crossings. Many places prefer USD over local currency exchange.
Is it safe to travel alone?
Yes, with normal precautions. South America has a huge backpacker trail with hostels everywhere. Avoid flashing valuables, don't walk alone at night in cities, and trust your gut. Women should research specific safety considerations for each country.
How much Spanish do I need?
Basic Spanish helps enormously outside tourist areas. Download Google Translate offline for each country before you go. Learn numbers, basic questions, and transportation vocabulary. Most hostels have English-speaking staff.
Should I book everything in advance?
No. Book international flights and first few nights only. The beauty of backpacking is flexibility—you'll want to stay longer in places you love and skip places that don't click. Only pre-book must-do activities with limited permits.
What if I get sick at altitude?
Ascend slowly, drink tons of water, avoid alcohol first 2 days. If you get severe altitude sickness (confusion, difficulty breathing), descend immediately. Coca tea and diamox help with mild symptoms. Most people adjust fine with 2-3 days at elevation.
