Where is Cerro Estrella?

Cerro Estrella, also called Lastarria, sits right on the border between Argentina (Salta Province) and Chile (Antofagasta). We're talking serious altitude here – the summit hits a whopping 17,680 feet (5,389m)!

Up top, you'll find the remains of Mina La Julia, an abandoned sulfur mine that was buzzing from the '50s to the late '70s. Now, it's a ghost town, a stark reminder of a bygone era.

Getting to the top is no joke! This isn't your Sunday drive. The road is an old mining track that demands a 4x4. Be ready for some seriously steep inclines.

A word of caution: this climb isn't for the faint of heart (literally!). The extreme altitude means less oxygen, which can be tough on the body. If you have any heart or breathing issues, seriously reconsider this one. Even if you're fit, be aware of altitude sickness – it can hit anyone! The air up there has only about 60% of the oxygen you're used to at sea level, so even simple tasks become a workout.

Oh, and heads up – this road is typically impassable during the winter months. The Andes throw everything they've got at it – heavy snow, blizzards that kill visibility, and crazy wind. Even in summer, be prepared for unexpected snow or sudden cold snaps. Powerful winds are pretty much a constant companion.
