How much clothing should I pack for a 3-week trip?

Pack for 7-10 days max, then do laundry. Bring 4 base layers, 2 pairs of pants, 3 shorts, and one warm layer. You'll find laundry services in every major town for $3-8 per load.

Do I need different gear for the Amazon vs the Andes?

Yes and no. Your base layers and rain gear work everywhere. Add rubber boots for Amazon walks and hand warmers for Andes nights. The layering system handles both if you pack right.

What's the biggest packing mistake for South America?

Bringing too much cotton clothing. Cotton kills in the mountains - it stays wet and cold. Stick to synthetic or merino wool fabrics that dry fast and insulate when damp.

Should I buy gear in South America or bring it?

Bring critical items like rain gear and warm layers. Quality outdoor gear is expensive and hard to find outside major cities like Buenos Aires or Santiago. You can buy basics like t-shirts and flip-flops anywhere.

What to pack for a South America multi-climate trip

Pack in layers for South America's diverse climates. Bring lightweight base layers, a warm fleece or puffy jacket, rain gear, and versatile clothing that works from Amazon humidity to Patagonian cold. Focus on quick-dry fabrics and pack for elevation changes of 10,000+ feet.

Choose your base layers. Pack 3-4 merino wool or synthetic base layers. These work in humid Amazon conditions and under warm layers in the Andes. Avoid cotton completely - it stays wet and cold at altitude.
Pack for temperature extremes. Bring a down or synthetic puffy jacket rated to 20°F (-7°C) for high-altitude nights. Pack lightweight long pants and shorts. You'll need both within the same day when crossing elevation zones.
Prepare for constant rain. Pack a proper rain jacket and pants - not a poncho. South America gets serious downpours from the Amazon to Patagonia. Your rain gear needs to handle 6+ hours of steady rain.
Plan footwear for varied terrain. Bring waterproof hiking boots and lightweight sneakers or sandals. The boots handle muddy jungle trails and rocky mountain paths. The light shoes give your feet a break in cities.
Pack altitude and sun protection. Bring SPF 50+ sunscreen, UV-blocking sunglasses, and a wide-brim hat. UV exposure increases 10-15% per 1,000 feet of elevation. You'll burn fast at 12,000+ feet even when it's cold.
Add climate-specific essentials. Pack insect repellent with 20%+ DEET for lowlands, hand warmers for high-altitude camps, and a quick-dry travel towel. Include electrolyte tablets for altitude adjustment and hot climate hydration.
