[SALTA PROVINCE, ARGENTINA] — Here’s a post about a roadtrip through Salta Argentina, the far northwest province of Argentina. All about exploring Salta province and the famed Ruta 40, which is one of the longest, notorious roads in the world. A roadtrip through Salta Argentina.

You probably haven’t heard much about Salta or Jujuy provinces, in the far northwest quadrant of Argentina and a roadtrip on its famed Ruta 40 highway, but word is starting to spread. This is one of the great roadtrips in the world. While everyone knows of Buenos Aires, Mendoza and Patagonia, it seems like Salta has just barely opened up.

You take a two hour flight from Buenos Aires to the city of Salta which you can use as a base, driving around the region — there are a number of road tours you can take from there — driving north to Jujuy province and the salt flats of Bolivia or West into the mountains and high altitude altiplano, or South through the red canyons to the Salteño wine town of Cafayate.  No matter which way you go, each road trip as amazing as the other.

This post will be about a circular roadtrip driving from Salta to the dusty Andean town of Cachi, down south via the notorious Ruta 40 to Cafayate, then back up to Salta. I split my trip into multiple days to stay in some cool hotels in the mountains (detailed in a companion post), but the route can be done in two days, or one if you’re brutal and have a strong vehicle.

In the few guidebooks in English, you read: “a four wheel drive is best,” but I balked after they wanted over a thousand bucks rent for a 4WD truck, so I parsimoniously rented a small crossover 4WD Peugeot mini SUV.  It was a surprising billygoat of a car, but after many harrowing close calls with washed out roads and fording rain-swollen rivers through the mountains, I would have paid five thousand dollars for a real 4WD.  You need a 4WD.  Your knuckles will be less white.

I’d pick an overnight destination, in nearly everything you read, every place is “a couple of hours” but I found the travel times to be much longer, the roads more arduous, the scenery beckoning you to stop every 10 kilometers.  Definitely don’t rush through this incredible scenery.

I left great green plains of Salta in the early morning, zig-zagging up the surprisingly scary rainforest canyons of the Cuesta de Obispo, crossing fallen boulders, pounding rains, slow moving trucks and narrow bridges that nearly washed me off a thousand foot cliff.

I call this the “Salta Loop” and it’s a common exploration route. I planned to break up the journey with stops at the isolated Estancia Colomé outside of Molinos, then overnight in Cafayate on the southern tip, before journeying up the red rocks canyons of the Quebrada de las Conchas, returning to my hotel in Salta.

From Rainforest to High Desert — Driving the Cuesta del Obispo From Salta to Cachi

Climbing from the lush plains of Salta city, you instantly are thrust into a rainforest, with curvy, crazy roads dodging up the canyons, crossing thin bridges and going against the roaring ruddy river. Zig. Zag. Cross. Stop. Take off your white knuckles. Catch breath. Continue on….

Then as you rise, you start to get into more canyons, rich and lush from the constant rains coming down from the clouds crossing the steep Andes.

Here’s what it was like, in my stupid-to-do one-handed video shot going through the rushing washed out road. I just had to because it was so frightening, nobody would believe me. You can’t tell, but my meek car started sliding with the current, just feet from the thousand foot drop on the left:

The Altiplano in Salta Argentina

As soon as you reach the top of the pass on Ruta 33 and the Cuesta del Obispo valley  (“The Bishop’s Slope”)  you suddenly hit the vast altiplano high desert of Salta, Argentina.  

At over 12,000ft in elevation, with endless views to the horizon, it literally and figuratively takes your breath away. it’s like a whole different situation from the lush tropical rainforest you just came through. And within minutes, from zig-zag and harrowing washouts on dirt roads, to straight as an arrow highway that looks like the deserts in Death Valley. Dry as a bone.

Driving the Notorious Ruta 40 from Cachi to Cafayate

In the northwest corner of Salta along the Chilean and Andean border, you run into the famed Ruta 40 — one of the longest, gnarliest highways in the world. It runs the entire length of Argentina, over 5,000km from tip to tail, from Bolivia down to the sea in Patagonia.

It’s at some of its wildest in Salta, where it’s less a highway than a rutted road, running through dusty Andes towns, fording rivers and scant gas stations. I hooked up with it in Cachi on my way to Molinos and it’s a slow ride, not just because of the rocky roads and bridgeless rivers to cross, but because there’s something amazing to stop and see nearly every other kilometer. Bring cheese.

At the end of Ruta 33 is the dusty town of Cachi. I mean it is a dusty Andean town. There are a couple of decent places to stay there, but I kept pressing on toward Estancia Colomé. From Cachi, you turn south and join up with the famous Ruta 40. You drive through dusty mountain towns like from a Spaghetti Western, and then go south along the Andes, fording rivers along the way. My goal was the Estancia Colome, many kilometers outside the small town of Molinos, stay a few days at this magical place and it’s James Turrell Museum and then head south to the wine town of Cafayate.

Here’s what it was like in person:

Google Ruta 40 and you’ll read all sorts of stories, some of them horror stories, about this famous long road down the spine of Argentina. I’ve heard they’ve started to pave and straighten some parts of Ruta 40 in recent years, but haven’t seen where or how far.

I’ve heard they’ve paved some sections recently, perhaps the gnarliest parts, but I’m not sure where or how far.  These photos are from my visit there in March of 2011. If you have info, please send it to me.

Rambling Through the Moonscape of Quebrada de Las Flechas

Driving through Quebrada de las Flechas was the most scenic and moonscape-y part of the trip. And one of the most famous sections of Ruta 40. Giant thrusts of stone pointing to the sky in the aptly named “Canyon of the Arrows”.  Plan to spend some time in this section as the views are so good you’ll want to stop you car and get out every 1/2 kilometer. As I did, cough-cough.

It’s just so crazy how much the landscape changes from one ecosystem to the next in the span of an hour. From lush steep canyons, to flat high deserts to the jagged maw of rock of the Quebrada de las Flechas.

Then the land starts to flatten out, with squat valleys surrounded by jagged mountain ridges. Wineries pop up here and there, strangling water from the craggy ground to make high-altitude Malbec.

As you near Cafayate, the valleys get broader, the muddy Calchaqui, wider.  The colors shockingly redder.

Driving North, from Cafayate to Salta through the Quebrada de las Conchas

After an overnight in Cafayate, you head north through the canyons of the Calchaquí Valleyand the stunning Quebrada de las Conchas (Shell’s Gorge) (click that link for an awesome overview)  where suddenly, everything is deep red. One thousand shades of red, changing around every corner. You can see it from space… this is not an infrared photo, it’s the real thing:

This whole region is like Sedona Arizona… on steroids. It’s like seeing when Earth was created.

Look for the small wooden sign for the Amphitheater (El Amfiteatro) and pull off. It’s a naturally formed, wind-carved canyon that soars 200 feet on all sides.  The acoustics are so good, they hold concerts here.. and there will invariably be a Salteño music group strumming in the perfect acoustics for tips.

The rushy muddy river gouges at the red rock.  All these saturated colors, you almost have to wipe your eyes it’s so overwhelming. It’s like swimming in red.

Northern Salta and Jujuy Province

Northern Salta and Jujuy Province are just as amazing as the southern part of the state. Just more colors. I made a huge post about these two amazing places here.

And also a giant open plain devoid of color — the Salinas Grandes, one of the world’s largest salt flats. Where the Quebrada de Conchas was like swimming in red, this is like swimming in whites and blues, like Heaven. Here’s a post I made about Salinas Grandes.

Salta City

The city of Salta, called “Salta the Beautiful” by swooning Argentinians is a gorgeous little city. I was only able to duck into it for lunch on my way to the airport. But there are some nice hotels to check out there.

Here’s a great article in Conde Nast Traveler, and another on Salta City, and another Conde Nast Article on all the best hotels to stay in. that’s a great summary. Here’s an older NYTimes article on Salta The Beautiful, this is the article that brought me here.
