How to Pack for Backpacking South America

Pack layers for extreme climate variation, prioritize quick-dry fabrics, and bring a 40-50L backpack. You'll encounter everything from Andean snow to Amazon humidity to Patagonian wind. Pack light—you can buy basics locally for much less than at home.

  1. Choose your backpack size. Get a 40-50L backpack. Anything bigger tempts overpacking. Look for front-loading panels and compression straps. Skip wheeled bags—cobblestones and dirt roads will destroy them.
  2. Master the layer system. Base layer: 2 merino wool shirts. Mid layer: fleece or down jacket. Shell layer: waterproof rain jacket. This system works from Bolivian highlands (freezing) to Colombian coast (sweltering) in the same trip.
  3. Pack for wet seasons. Bring a packable rain jacket, quick-dry pants, and waterproof stuff sacks. Rain gear doubles as wind protection in Patagonia. Pack rain covers for electronics—humidity destroys phones faster than drops.
  4. Choose versatile footwear. One pair hiking boots, one pair casual shoes (for cities and hostels), flip-flops for showers. Skip specialized trekking shoes unless doing serious multi-day hikes—you can rent gear locally.
  5. Pack medical and safety essentials. Altitude sickness meds, water purification tablets, insect repellent with DEET, and a basic first aid kit. Include anti-diarrheal medication and oral rehydration salts—both inevitable.
  6. Minimize electronics. Phone with offline maps, power bank, universal adapter, headlamp, and backup charging cables. Skip hair dryers and multiple cameras—your phone camera is sufficient for most travelers.
Can I buy gear locally in South America?
Yes, especially basics like clothes and rain gear. Buenos Aires, Santiago, and Bogotá have excellent outdoor stores. Avoid buying technical gear in tourist areas—prices are 2-3x normal rates. Local markets are perfect for everyday clothing.
How do I pack for altitude changes?
Layer system is crucial. You might start in sea-level Lima (75°F) and be in 12,000-foot Cusco (40°F) the next day. Pack a down jacket that compresses small and merino wool base layers that regulate temperature.
What about laundry while backpacking?
Laundromats are common and cheap ($2-5 per load). Many hostels offer laundry service. Pack quick-dry fabrics and enough underwear for 7-10 days. Hand-washing in hostel sinks works for small items.
Should I bring camping gear?
Only if planning specific camping trips. Hostels and budget hotels are abundant and cheap ($8-20 per night). Camping gear adds significant weight and bulk for minimal savings. Rent gear locally for trekking.
