How to Pack for Solo Travel in South America

Pack light with versatile layers, a 40-50L backpack, and gear that handles altitude changes, humidity, and basic infrastructure gaps. Focus on quick-dry fabrics, a reliable water purification system, and items that work across climates from Patagonian cold to Amazon heat.

  1. Choose your backpack size. Get a 40-50L backpack maximum. Anything bigger becomes a burden on long bus rides and hostel stairs. Osprey Farpoint 40 or REI Trail 40 work well. Test the fit with weight before buying.
  2. Layer for altitude and climate variety. Pack a base layer system: merino wool base layer, fleece or down mid-layer, waterproof shell. You'll hit 14,000+ feet in Bolivia and sweltering heat in lowland areas. Avoid cotton except for one pair of comfortable pants for cities.
  3. Pack water purification. Bring a LifeStraw or Sawyer Mini plus water purification tablets. Tap water varies wildly between countries. Having both gives you backup options when bottles aren't available or affordable.
  4. Include basic medical supplies. Pack altitude sickness medication (diamox if your doctor approves), basic first aid kit, anti-diarrheal medication, and any prescriptions with extra buffer. Pharmacies are common in cities but scarce in remote areas.
  5. Prepare for electronics needs. Bring a universal adapter, portable battery pack, and headlamp with extra batteries. Power outages happen, outlets vary by country, and you'll need light for early morning bus departures or late hostel arrivals.
  6. Pack documents securely. Keep physical and digital copies of passport, visas, vaccination records, and insurance. Store copies separately from originals. Many borders still require paper vaccination certificates.
Do I need hiking boots for South America?
Lightweight hiking shoes work better than boots unless you're doing serious trekking. Many trails are muddy, and lighter shoes dry faster. Bring one pair of comfortable walking shoes for cities.
How many clothes changes should I pack?
5-7 days maximum. You'll do laundry frequently since you're carrying everything. Focus on items that layer well and dry quickly rather than having many pieces.
Should I bring a sleeping bag?
Bring a sleeping bag liner instead unless camping. Most hostels provide bedding, but a liner adds hygiene and warmth on cold buses or basic accommodations. Takes less space than a full sleeping bag.
What about insect protection?
Pack DEET-based repellent (20-30%) and permethrin-treated clothing if heading to jungle areas. Long pants and sleeves for evenings in mosquito-heavy regions. Most locals wear long sleeves at dusk.
