How to plan a 3-month backpacking route through South America

Focus on three distinct regions rather than trying to see the entire continent to avoid spending half your trip on buses. Allocate 4 weeks to the Andes, 3 weeks to the Southern Cone, and 5 weeks to the Amazon and Caribbean coast.

Select your entry point. Fly into a major hub like Bogotá (Colombia), Lima (Peru), or Buenos Aires (Argentina) to get cheaper long-haul flights. Use these as your anchor points.
Master the 'Bus vs. Fly' balance. South America is massive. If a bus ride exceeds 15 hours, pay for a budget flight (LATAM or Sky Airline). For shorter distances, use overnight 'cama' buses to save on a night of accommodation.
Sequence by altitude. Start at lower altitudes and gradually move into the Andes (e.g., Cusco or La Paz) to avoid severe altitude sickness. Spend at least 3 days acclimatizing at each 1,000-meter increase in elevation.
Book international borders in advance. While you can wing daily travel, book bus tickets for major border crossings (like Argentina to Chile) at least 48 hours ahead during peak season (December–February).
