Is 3 weeks enough for South America with kids?

Yes, but stick to 3-4 countries maximum. More countries means more travel time and less actual sightseeing. The Peru-Bolivia-Argentina-Brazil route covers major highlights without rushing.

What's the best age for kids on this trip?

Ages 8+ handle the altitude and walking better. Younger kids can do it but need more rest days and shorter activity days. Machu Picchu requires significant walking on uneven terrain.

How do I handle altitude sickness with children?

Arrive in high-altitude cities (Cusco, La Paz) and take it easy the first day. Pack children's altitude medication after consulting your pediatrician. Coca tea helps adults but not recommended for kids.

Should I book a tour or travel independently?

Mix both. Book tours for Machu Picchu and Uyuni Salt Flats (logistics are complex). Handle cities like Buenos Aires and Rio independently with day tours for specific sights.

What vaccinations do we need?

Yellow Fever if visiting Amazon regions. Routine vaccines should be current. Hepatitis A recommended. Consult travel clinic 4-6 weeks before departure for personalized advice.

How to Plan a 3-Week South America Family Itinerary

Plan a 3-week South America family trip by choosing 3-4 countries maximum, booking flights 3 months ahead, and focusing on family-friendly highlights like Machu Picchu, Iguazu Falls, and Rio beaches. Budget $4,000-6,000 per family of four including flights.

Choose your route. Pick 3-4 countries maximum. The classic family route: Peru (Lima, Cusco, Machu Picchu) → Bolivia (La Paz, Uyuni Salt Flats) → Argentina (Buenos Aires, Iguazu Falls) → Brazil (Rio, São Paulo). Alternative: Ecuador (Quito, Galápagos) → Peru → Chile (Santiago, Atacama Desert) → Argentina.
Book flights early. Book international flights 3 months ahead. Fly into Lima or São Paulo for best prices. Book the multi-city ticket: US to Lima, Buenos Aires to US costs $800-1200 per person. Internal flights between countries run $200-400 each.
Plan around school breaks. June-August is peak season but also winter in southern countries. December-February is summer but more expensive. April-May or September-October offer good weather and lower crowds. Book accommodations 6-8 weeks ahead during peak times.
Handle altitude preparation. Cusco sits at 11,200 feet. Arrive 2 days early to acclimatize before Machu Picchu. La Paz is even higher at 12,000 feet. Pack altitude sickness medication and plan easier days upon arrival in high-altitude cities.
Organize visas and documents. US citizens need no advance visas for Peru, Bolivia, Argentina, Brazil, Chile, or Ecuador for stays under 90 days. Ensure all passports have 6+ months validity. Get Yellow Fever vaccination if visiting Amazon regions.
Book must-do experiences. Reserve Machu Picchu train tickets 2 months ahead ($65 per person). Book Galápagos cruise 3-4 months early ($1,500+ per person for 4 days). Iguazu Falls needs 1 day minimum. Christ the Redeemer in Rio requires advance online tickets.
