Alto de Chorillos: Driving to 4,806m in the Argentine Puna

Okay, buckle up, adventure junkies! We're heading to the wild, wild northwest of Argentina, to Salta province, where the Alto de Chorillos peak awaits. At a mind-blowing 4,806m (that's 15,767ft!), you'll feel like you've landed on another planet – seriously, the Puna de Atacama desert is *out there*.

Your trek starts from the main RN51 highway (can't miss it!). From there, it's a 6.2km (3.8-mile) scramble to the top. The road's gradient is manageable, but the altitude? That's the real beast. Expect your engine to lose some serious oomph up here! This is a gravel road, all tight switchbacks and sneaky loose patches, so a 4x4 is essential for tackling those ramps leading to the LLAMA astronomical observatory.

Speaking of beasts, this road can be a real monster, especially when winter snow hits. It's often impassable and can close anytime the snow gets too deep. Even a bit of rain can turn the dry ground into a muddy trap! And if you're not a fan of heights, be warned: sheer drops and narrow sections with zero barriers will test your nerve. Prep is KEY! Ensure your cooling system is tip-top, and pack extra oxygen, because altitude sickness (soroche) is no joke.

The climate up here in the Puna is harsh. Temperatures range from mild to…well, freezing. Expect highs in the teens (Celsius), but be aware that nights (and midwinter) can drop to well below zero. Rain usually comes in summer, often in sudden, dramatic bursts. Oh, and did I mention the constant wind and intense sun? Pack water, lots of it, and make sure your vehicle's fluids are topped up.

The payoff? Besides bragging rights, you'll reach one of South America's coolest scientific spots. The LLAMA observatory is perched up here because the air is so dry and thin, making for crystal-clear stargazing. Getting to the top is a true test of self-reliance. There are no services, no water, no help for miles! Pack your recovery gear and emergency supplies, and get ready for an unforgettable ride.
