Should I pack hiking boots for South America?

Only if you plan serious multi-day treks like the Inca Trail or Torres del Paine. Otherwise, trail runners or sturdy sneakers handle 90% of South America travel including day hikes. Boots take up too much space and weight for long-term packing.

How much clothing do I actually need for 6 months?

One week's worth. Laundry is cheap ($3-8 per load) and available everywhere. Wash every 5-7 days. More clothing just means heavier bags on overnight buses and more stolen if your bag goes missing.

Do I need a sleeping bag?

Not unless you are camping or doing the Inca Trail. Hostels and budget hotels provide bedding. A sleeping bag liner ($15-25) works for questionable sheets and adds warmth in cold highland hostels without the bulk.

What about altitude sickness medication?

Get acetazolamide (Diamox) prescription before you leave if visiting Cusco (3,400m), La Paz (3,640m), or Quito (2,850m). Also available at pharmacies in those cities without prescription. Bring ibuprofen and drink coca tea. Altitude is real—plan for it.

Can I mail things home if I overpack?

Yes, but it is expensive and slow. International shipping from South America costs $40-100+ for a 5kg box and takes 4-8 weeks. Better to sell or donate excess gear locally and replace it cheaply if needed later in your trip.

Pack for Long-Term Travel in South America

For long-term South America travel, pack a 40-50L backpack with layerable clothing for diverse climates, quick-dry fabrics, and gear that handles humidity and altitude. Plan for 20-30°C coastal heat, 5-15°C Andean cold, and everything between. Bring less than you think—laundry is cheap and available everywhere.

Choose the right bag. Use a 40-50L backpack with hip belt and compression straps. Anything larger becomes unwieldy on overnight buses and cobblestone streets. Add a 20L daypack that stuffs inside the main bag. Skip wheeled luggage—South American infrastructure favors backpacks.
Build a climate-flexible wardrobe. Pack 5 shirts, 2 pants, 1 shorts, 1 warm layer, 1 rain jacket, 7 underwear, 5 pairs of socks. Use the layer system: base layer for heat, mid-layer for cool evenings, outer layer for Andean cold and rain. Merino wool or synthetic quick-dry only—cotton takes days to dry in humid climates.
Add altitude and rain protection. Bring a packable down jacket or synthetic puffy (5-15°C nights in Cusco, La Paz, Quito), waterproof rain jacket, and waterproof bag cover. The Andes get cold. The Amazon gets wet. Pack for both.
Pack electronics conservatively. Phone, charging cables, universal adapter, power bank, headphones. Add e-reader if you read. Add laptop only if you work remotely. Outlets are 220V in most countries—check your gear. Theft is a reality—keep it minimal.
Include health and hygiene essentials. Small toiletry kit with toothbrush, toothpaste, soap, shampoo, sunscreen SPF 50+, insect repellent with DEET, and any prescription meds for 3 months. Add altitude sickness prevention if hitting 2,500m+ (Cusco, La Paz, Bogotá). Buy replacements locally—pharmacies are everywhere.
Add South America-specific gear. Dry bag for Amazon/Pantanal trips, headlamp for power outages and early bus departures, Spanish phrasebook or offline translation app, water bottle with filter or purification tablets. Microfiber towel. Padlock for hostel lockers. Ziplock bags for phone protection in rain.
Leave room for acquisitions. Pack to 70% capacity. You will buy alpaca sweaters in Peru, yerba mate gourds in Argentina, or hammocks in Colombia. Plan for it.
