South America One Month Itinerary: How I Planned the Trip of a Lifetime (And What I’d Do Differently)

Here’s a wild stat for you — South America covers over 17.8 million square kilometers, and I somehow thought I could “see it all” in 30 days. Spoiler alert: I couldn’t. But honestly? That one month was the most transformative travel experience I’ve ever had, and I’ve been chasing that feeling ever since!

Planning a South America one month itinerary can feel totally overwhelming. There’s so many countries, landscapes, and cultures competing for your attention. So let me break down exactly what worked for me, what didn’t, and how you can build your own route without losing your mind.

Week 1: Lima and Cusco, Peru

I started in Lima, and let me tell you, I almost made the rookie mistake of skipping it entirely. Don’t do that. The food scene alone is worth two full days — I’m talking ceviche that literally changed my understanding of fish.

From Lima, I flew to Cusco and spent a couple days acclimatizing to the altitude. This part is non-negotiable, folks. I ignored that advice on a previous trip and ended up with the worst headache of my life, basically bedridden for a whole day.

The highlight was obviously Machu Picchu, and I’d recommend booking the Inca Trail at least six months in advance. If that’s sold out, the Salkantay Trek is a gorgeous alternative that doesn’t get nearly enough love.

Week 2: Bolivia’s Surreal Landscapes

Next, I crossed into Bolivia. And this is where things got really interesting. The bus from Cusco to La Paz takes around seven hours, and the border crossing was chaotic but manageable if you have your documents ready.

I spent a night in La Paz — which is honestly one of the most underrated cities on the continent — before heading to Uyuni for the famous salt flats. A three-day jeep tour across the Salar de Uyuni was hands down the most surreal experience of the entire trip. Like, you’re standing on an endless white mirror and your brain just can’t compute it.

One mistake I made here was not bringing enough warm layers. The desert gets brutally cold at night, even when daytime temps feel pleasant.

Week 3: Buenos Aires and Patagonia, Argentina

I flew from La Paz to Buenos Aires, and the vibe shift was massive. Buenos Aires feels like a European city that got dropped into South America, with incredible steakhouses, tango shows, and neighborhoods like San Telmo that ooze character.

After two days there, I took a flight down to El Calafate to see Perito Moreno Glacier. Now, internal flights in Argentina can be pricey, so book early or look into the Argentina airpass if it’s still being offered. Watching chunks of ice the size of buildings crash into the water below was absolutely humbling.

If your budget allows, a day trip into Torres del Paine across the Chilean border is incredible too. I didn’t have time and I still regret it.

Week 4: Rio de Janeiro and Iguazu Falls, Brazil

For the final stretch, I flew to Iguazu Falls, which straddles the Argentina-Brazil border. Pro tip — visit both sides. The Argentine side lets you get up close, while the Brazilian side gives you the panoramic money shot. I was genuinely moved to tears standing on those walkways.

I finished the trip in Rio de Janeiro, and what a way to end it. Copacabana, Sugarloaf Mountain, Christ the Redeemer — it’s all as epic as the photos suggest. I spent three glorious days just soaking it in, eating açaí bowls on the beach, and reflecting on the whirlwind month.

Your Turn to Pack That Bag

Look, my South America one month itinerary wasn’t perfect. I rushed a few spots and lingered too long in others. That’s totally fine — the beauty of a trip like this is making it yours. Maybe you swap Bolivia for Colombia, or skip Buenos Aires for Mendoza wine country instead.

Just remember to get travel insurance, keep copies of your passport, and always have some local currency on hand for border crossings. South America is incredibly rewarding, but it demands a little flexibility and a lot of patience.
