Pack for a Family Trip to South America

Pack layers for dramatic climate changes, keep documents secure in waterproof pouches, and bring a daypack per person for excursions. Most families need one checked bag per person plus carry-ons with medications, a change of clothes, and entertainment for kids. Plan for cool mornings and warm afternoons, even in the same city.

  1. Start with the base layer system. Pack thin base layers that dry quickly. Cotton fails in the Andes and Amazon humidity. Bring moisture-wicking shirts and convertible pants for each family member. Kids need 1 outfit per day plus 2 extras. Adults can repeat outfits. Pack compression bags to save 30-40% of suitcase space.
  2. Add mid-layers for altitude. Bring a fleece or light down jacket for everyone. Cusco, La Paz, and Quito sit above 2,800 meters where mornings start at 5-10°C even in summer. Pack one warm layer that works over everything else. Skip bulky sweaters. A packable down jacket weighs 300 grams and compresses to the size of a water bottle.
  3. Rain gear that actually works. Pack a rain jacket with a hood for each person. The Amazon basin gets 2,000-3,000mm of rain annually. Coastal Peru stays dry, but southern Chile and Argentina see regular rain. Bring a small packable poncho for each child that fits over a backpack. Test zippers before you go.
  4. Footwear: two pairs per person maximum. Everyone needs sturdy walking shoes or light hikers broken in before departure. Add sandals or flip-flops for beach destinations, showers, and hot days. Skip fashion shoes. Cobblestones in Cartagena, Cusco, and Buenos Aires destroy heels and flimsy sneakers. Kids' feet swell in heat—pack shoes with room to grow.
  5. Organize documents in waterproof cases. Use a waterproof document pouch for passports, vaccination cards, and photocopies of everything. Bring 3 copies of passport photo pages—one stays at your hotel, one in your daypack, one in checked luggage. Keep birth certificates for children if traveling with only one parent. Some countries require notarized permission letters from the absent parent.
  6. Pack a daypack for each family member. Each person needs a small backpack for day trips. Pack water bottles, sunscreen, snacks, a light rain layer, and a small first aid kit. Kids should carry their own water and entertainment. Excursions to Machu Picchu, Iguazu Falls, and Patagonia involve hours of walking where you cannot easily return to your hotel.
  7. Medical kit specific to the region. Bring altitude sickness medication if visiting above 2,500 meters. Pack oral rehydration salts, anti-diarrheal medication, antihistamines, and any prescriptions with 25% extra. Include insect repellent with 20-30% DEET for the Amazon and tropical lowlands. Bring children's pain reliever and a thermometer. Pharmacies exist in cities, but rural areas offer limited options.
  8. Electronics and power adapters. South America uses type A, C, and I outlets depending on the country. Bring a universal adapter that covers all three. Pack external batteries for phones—you will use maps constantly. Download offline maps for each city before arrival. Bring a waterproof phone case for boat trips and rain. Kids need headphones and downloaded entertainment for long bus rides.
  9. Assemble your carry-on survival kit. Pack a complete change of clothes for each family member in carry-on bags. Include medications, toiletries, phone chargers, snacks, and one day's worth of entertainment. Checked bags get delayed. You may arrive in Lima but your luggage may arrive two days later. A carry-on with essentials keeps your first 48 hours functional.
Can I buy what I forgot in South American cities?
Yes in major cities, harder in smaller towns. Lima, Buenos Aires, Santiago, and Bogotá have pharmacies, outdoor stores, and general shops comparable to North American or European cities. Prices may run 20-50% higher than home. Rural areas and small towns offer limited options. Pack essentials like prescription medications, specific brands of contact lens solution, and preferred children's pain relievers from home.
How much luggage space do compression bags actually save?
Compression bags reduce clothing volume by 30-40% in real-world packing. A week's worth of clothes for one person that normally fills a 40-liter space compresses to about 25-28 liters. They work best for soft items like fleece jackets, cotton shirts, and pajamas. They do not reduce weight, only volume. Roll-style compression bags work better than vacuum bags for travel since you can compress by hand.
Do children really need their own daypacks?
Yes for children 5 and older. A child carrying their own water, snacks, and light jacket reduces parent load and teaches responsibility. Size the pack appropriately—a 10-liter pack for ages 5-8, a 15-liter pack for ages 9-12. Excursions to Machu Picchu, Torres del Paine, and Iguazu Falls involve 4-6 hours of walking. Parents cannot carry everything for multiple children on these trips.
What if my child gets altitude sickness?
Descend to lower altitude immediately if symptoms worsen. Pack acetazolamide (Diamox) for children over 12 if prescribed by your doctor. For younger children, ascend slowly, stay hydrated, and monitor for headache, nausea, and fatigue. Spend 2 nights in Cusco (3,400m) before going to higher elevations. Skip destinations above 3,500 meters with children under 5. Severe altitude sickness requires medical attention—descend first, then find a clinic.
Should I pack a stroller for South America?
Only if your child is under 2 and you are staying in major cities. Cobblestone streets in historic districts destroy standard strollers. Carry a lightweight umbrella stroller or a baby carrier instead. A soft-structured baby carrier works better for markets, archaeological sites, and uneven terrain. Strollers prove useless at Machu Picchu, the Amazon, and most hiking destinations.
