Why Backpack South America?

South America is a continent of extremes. Snow-capped Andes peaks, the Amazon rainforest, Atacama Desert, Patagonian glaciers, Caribbean beaches, and some of the most vibrant cities on Earth. The backpacking infrastructure has improved enormously in recent years, and it remains one of the most affordable continents for long-term travel.

A 3-month route through South America will cost roughly $3,000–5,000 (excluding international flights), give you extraordinary experiences and change your perspective on the world.

  4. Negotiate β€” In Bolivia and Peru, always ask "hay descuento?" (is there a discount?)

Getting Around

Buses

Long-distance buses are the backbone of South American travel. They range from basic to luxurious:

  • Semi-cama β€” Reclining seats (130 degrees), the budget option
  • Cama β€” Fully reclining (160-180 degrees), worth the upgrade for overnight journeys
  • Night buses β€” Save on accommodation. Buenos Aires to Mendoza: 14 hours, $25-35

Flights

Budget airlines make some long distances viable:

  • JetSMART β€” Chile and Argentina, flights from $30
  • Sky Airline β€” Chile and Peru
  • Viva Air β€” Colombia
  • Wingo β€” Colombia and Ecuador

Tip

Book bus tickets on Busbud or directly at the terminal. In Peru, use Cruz del Sur or Oltursa for the safest, most comfortable services. In Argentina, Plataforma 10 is the main booking site.

Overland Border Crossings

All borders on this route are straightforward:

  • Colombia to Ecuador β€” Ipiales/Tulcan border, safe and efficient
  • Ecuador to Peru β€” Huaquillas/Tumbes or Macara/La Tina
  • Peru to Bolivia β€” Puno/Copacabana (Lake Titicaca), a beautiful crossing
  • Bolivia to Argentina β€” Villazon/La Quiaca, or fly La Paz to Buenos Aires
  • Argentina to Chile β€” Bus from Mendoza to Santiago (7 hours, stunning Andes crossing)

Food on a Budget

South American food is cheap and delicious. Budget strategies:

  • Set lunch menus (almuerzo/menu del dia) β€” A full meal for $1.50-4 in most countries
  • Markets β€” Every city has a central market with cheap food stalls
  • Cook in hostels β€” Supermarkets are affordable, cook dinner to save

Essential Tips

Safety

  • South America is generally safe for backpackers, but use common sense
  • Avoid walking alone at night in unfamiliar areas
  • Use official taxis or apps (Uber works in most major cities, InDrive is popular)
  • Keep copies of your passport and store originals in your hostel safe
  • Do not wear flashy jewellery or wave expensive phones around

Health

  • Vaccinations β€” Yellow fever is required for the Amazon. Carry your certificate
  • Altitude β€” Coca tea, slow acclimatisation, and drink 3+ litres of water daily
  • Sun β€” The Andean and Atacama sun is brutal at altitude. SPF50, hat, sunglasses
  • Water β€” Tap water is not safe to drink in most countries. Carry a reusable bottle with a filter

Money

  • ATMs β€” Withdraw in cities, not small towns. Fees vary: $2-5 per withdrawal
  • Cash is king β€” Especially in Bolivia and rural areas
  • USD β€” Accepted in Ecuador (official currency) and useful as backup everywhere
  • Haggling β€” Expected at markets and with taxis. Not appropriate in restaurants or shops

Language

  • Spanish is essential. Unlike Southeast Asia, English is not widely spoken
  • Learn basic phrases before you go. Even bad Spanish is appreciated
  • Download Spanish on Google Translate for offline use
  • Take a Spanish class in Bogota, Cusco or Buenos Aires ($5-10/hour for private lessons)

Info

Duolingo is a good starting point, but nothing beats a week of immersion classes. Bogota and Cusco are popular for affordable Spanish schools, with group classes from $50-80 per week.

Packing List Essentials

  • Lightweight backpack (40-50L is the sweet spot)
  • Quick-dry clothing layers (temperatures vary from tropical to freezing)
  • Waterproof jacket (essential for Patagonia and the Amazon)
  • Warm fleece or down jacket (for altitude and Patagonia)
  • Good hiking boots (broken in before the trip)
  • Reusable water bottle with filter
  • Head torch
  • Padlocks for hostel lockers
  • Universal adapter
  • Dry bag for rainy boat trips and beach days

When to Go

  • Colombia β€” Year-round, December-March driest
  • Ecuador β€” Year-round, June-September driest in highlands
  • Peru β€” May-September (dry season in the Andes). Avoid January-March for Inca Trail
  • Bolivia β€” May-October (dry season). Salt flats mirror effect: February-April (wet)
  • Argentina β€” October-April for Patagonia. Year-round for Buenos Aires
  • Chile β€” October-April for Patagonia. Year-round for Atacama
