Planning a 3-Month South America Backpacking Route

To see the highlights of South America in 90 days, focus on one or two regions—the Andes (Peru, Bolivia, Ecuador) or the Southern Cone (Chile, Argentina)—rather than trying to cover the entire continent. You will need to prioritize bus travel and internal flights to bridge the massive distances efficiently.

1. Select a primary anchor region. Do not attempt to do Colombia, Brazil, and Patagonia in one trip. Pick a core theme. For nature and culture, choose the Andean circuit. For wine, mountains, and urban life, choose the Southern Cone.
2. Map your bus versus flight routes. South America is vast. Use buses for distances under 12 hours. For anything over 15 hours, pay the $100-$150 for a flight. Use sites like Busbud or Recorrido to check schedules before finalizing dates.
3. Buffer for altitude and transit. Add two extra days to every destination above 3,000 meters to account for altitude sickness. Add a 'rest day' every 7 days to avoid long-term traveler burnout.
4. Secure your cross-border logistics. Check visa requirements for each country in your route. Use the IATA Travel Centre to verify if you need a yellow fever vaccination certificate, which is mandatory for certain border crossings between tropical countries.

Is it safe to travel alone in South America for 3 months?

Yes, if you stick to the 'gringo trail' and use common sense. Use registered taxis, keep your phone tucked away in crowded areas, and keep your passport locked in a hostel locker.

Do I need to book my buses in advance?

Only for major holidays or popular routes like Cusco to Lima. Otherwise, booking 24-48 hours in advance at the terminal is usually cheaper and more flexible.
