730 Days in South American Wilderness: An Expedition That Changed Everything

Two years. Seven countries. Forty-three national parks. South America rewired my nervous system.

Why South America

I'd done the standard European circuits twice, the Southeast Asian circuit once. I wanted somewhere that required actual preparation — where you couldn't just show up with a credit card and expect things to work. South America, especially the southern cone, still has large areas where plans break down, logistics become negotiation, and the reward is proportional to the effort.

Argentina: The Patagonian Scale Problem

Patagonia doesn't fit inside your eyes. Standing at the Perito Moreno glacier — 30km wide, 60m tall at its face — I experienced what geographers call "overview effect": the vertigo of genuine scale, the feeling that you are small in a way that matters.

I spent three weeks trekking the W Circuit in Torres del Paine (Chile) and O Circuit (a rarer permit). The O is 9-10 days of camping, 130km, with elevation changes that test every piece of gear you own. On day 7, in a snowstorm at 1800m, I questioned the expedition project comprehensively.

By day 9, back at the park entrance, I was already mentally planning to return.

Bolivia: Altitude and Otherworldliness

The Salar de Uyuni — the world's largest salt flat — creates optical illusions at scale. In the rainy season, a few centimeters of water turns the surface into a perfect mirror that reflects the sky, creating the impression of walking on clouds.

La Paz sits at 3600m, its cable car system threading between the canyon walls and the markets of the indigenous neighborhoods. Altitude sickness hit me for three days; local remedy was coca leaf tea, which actually works. After a week, my body adapted and I could walk the city without gasping.

Colombia: The Rewritten Country

Colombia has the most complete image rehabilitation of any country I've visited. Medellín — once the world's most dangerous city — is now a case study in urban renewal: the cable car connects the hillside comunas that were once no-go zones to the city center; Parque Explora, a science museum, was built as a public good for neighborhoods that previously had no public infrastructure.

The coffee region (Eje Cafetero) is an aesthetic revelation: green mountains terraced with coffee plants, colorful colonial towns, and the warmest people I've encountered in two years of travel.

What 730 Days Teaches

Long-term travel strips away the curated version of yourself. When you're tired, when logistics have failed, when you're sick in a city where you don't speak the language — the version of yourself that's left is closer to the real one.

South America didn't make me a better person. It showed me, more clearly, who I already was.
