Driving in Salta & the NOA

Self-driving is the single best way to experience Northwestern Argentina. The NOA's six iconic routes — the wine-country run to Cafayate through the Quebrada de las Conchas (Ruta 68), the UNESCO World Heritage drive through the Quebrada de Humahuaca (RN 9), the high-altitude crossing to the Salinas Grandes salt flats (Ruta 52), the mountain pass descent to colonial Cachi (RP 33), the wild and remote Ruta 40 through the Valles Calchaquies, and the vertiginous road to the isolated village of Iruya — are among the most spectacular drives in South America. No bus schedule or tour itinerary can match the freedom of stopping where you want, for as long as you want, at landscapes that demand contemplation. This guide covers every route in detail: kilometer-by-kilometer breakdowns, road surface conditions, altitude profiles, fuel availability, safety considerations, best seasons, and car rental logistics. Whether you're planning a 3-day loop or a 2-week comprehensive circuit, this is the only road trip guide to the NOA you'll need.

Route Overview Map

The six main routes form a network that can be combined into various loop itineraries. All routes radiate from Salta city. Here is the big-picture summary before we dive into each route:

Route 1: Salta to Cafayate via Ruta 68 — The Wine Country Classic

Overview

The most popular drive in the NOA and arguably the most accessible spectacular road in all of Argentina. Ruta Nacional 68 runs 190 km south from Salta to Cafayate through the Quebrada de las Conchas (Canyon of Shells), a dramatic gorge carved through layers of red, orange, pink and cream sandstone over millions of years. The road is entirely paved, well-maintained, and any rental car handles it easily. Allow 3 hours of driving time, but budget 5-6 hours with photo stops — you will want to stop constantly.

Kilometer-by-Kilometer Breakdown

• Salta → El Carril (km 0-45): flat agricultural valley road. Tobacco and vegetable fields. Easy driving, no scenery of note. Speed limit 110 km/h.
• El Carril → Alemania (km 45-90): the road enters the foothills. Rolling terrain, occasional river views. The old train station at Alemania is a worthwhile brief stop (abandoned station with photogenic ruins).
• Alemania → Quebrada de las Conchas entrance (km 90-105): the landscape transforms. Canyon walls begin rising on both sides. Colors shift from brown to red.
• Quebrada de las Conchas (km 105-170): the main event. Named rock formations with signed pull-overs appear every few kilometers. Must-stops:
  • Garganta del Diablo (Devil's Throat): short walk (300m) into a narrow red canyon. The acoustics are extraordinary. The most visited formation.
  • El Anfiteatro (The Amphitheatre): a natural circular chamber with incredible acoustics. Street musicians often play inside. Clap your hands and hear the echo bounce.
  • El Sapo (The Toad): a rock formation that uncannily resembles a sitting toad. Quick photo stop.
  • Los Castillos (The Castles): red and cream layered formations resembling castle ramparts. Best in late afternoon golden light.
  • El Fraile (The Friar): tall column that resembles a hooded monk. Brief stop.
  • Los Medanos (The Dunes): wind-sculpted sandstone that looks like frozen sand dunes.
  • Tres Cruces Viewpoint: panoramic view of the valley before the final descent into Cafayate.
• Final stretch → Cafayate (km 170-190): the canyon opens into the Cafayate valley. Vineyards appear on both sides. Arrival into the wine capital of the north.

Practical Information

• Road surface: 100% paved, good condition. Minor potholes possible.
• Fuel: fill up in Salta. Cafayate has several fuel stations. No fuel stops along the route itself.
• Vehicle: any standard rental car. No high clearance needed.
• Season: drivable year-round. Occasional flooding in heavy summer rains (January-February) but the paved road is rarely affected.
• Best light: afternoon (driving south) or morning (driving north). The late afternoon golden light on the red canyon walls is extraordinary.
• Return option: out-and-back on the same road, or continue south on Ruta 40 to the Quebrada de las Flechas (unpaved) and loop back via Cachi and RP 33.

Route 2: Salta to Quebrada de Humahuaca via RN 9 — The UNESCO Heritage Drive

Overview

Ruta Nacional 9 runs north from Salta through San Salvador de Jujuy and into the Quebrada de Humahuaca, a UNESCO World Heritage Site since 2003. This 310 km drive passes through a 155-kilometer-long geological marvel — a narrow mountain valley flanked by mineral-rich mountains in every color of the spectrum. The road connects the major towns of Purmamarca, Tilcara, Humahuaca and (with a detour) the spectacular Hornocal 14-Colors Mountain. Entirely paved, well-maintained, and suitable for any vehicle.

Stage-by-Stage Breakdown

• Salta → San Salvador de Jujuy (100 km, 1.5h): autopista (dual carriageway) for the first 60 km, then single-lane highway. Industrial outskirts give way to tobacco fields and sugar cane. San Salvador de Jujuy is the capital of Jujuy province — pass through or stop briefly at the cathedral on the central plaza. Fuel available.
• San Salvador de Jujuy → Purmamarca (65 km, 1h): the road enters the Quebrada. Canyon walls begin rising. The turn-off to Purmamarca is signed (Ruta 52 junction). Purmamarca sits at the base of the Cerro de los Siete Colores (Hill of Seven Colors) — one of the most photographed mountains in Argentina. Allow 1-2 hours in Purmamarca: Paseo de Los Colorados walking loop (3 km, 1 hour), artisan market on the plaza, coffee and pastries. This is also the junction for Ruta 52 to the Salinas Grandes (see Route 3 below).
• Purmamarca → Tilcara (25 km, 30 min): climbing through the Quebrada. Increasingly dramatic multi-colored mountains. Tilcara is a larger town with restaurants, hotels, artisan shops and two must-visit sites: the Pucara (pre-Inca fortress ruins on a hill, easy 30-minute walk with panoramic views) and the Garganta del Diablo (short gorge hike). Fuel available in Tilcara.
• Tilcara → Humahuaca (40 km, 45 min): the valley narrows, colors intensify. Pass through the tiny hamlet of Uquia (stop at the church to see the "Angeles Arcabuceros" — 17th-century paintings of angels with muskets, unique in the Americas). Humahuaca is a historically significant town with the Monumento a los Heroes de la Independencia (climbed by stairs), an excellent artisan market, and the departure point for the Hornocal 14-Colors Mountain side trip.
• Hornocal Side Trip (80 km round trip from Humahuaca, 2h): the Serrania de Hornocal is a jaw-dropping 14-color mountain ridge at 4,350m. The road from Humahuaca is unpaved and climbs steeply — high clearance recommended, 4x4 in wet conditions. The viewpoint at the top is one of the most spectacular vistas in South America. Bring warm layers (it is cold and very windy at 4,350m even on sunny days). Not recommended after rain.

Practical Information

• Road surface: RN 9 is 100% paved from Salta to Humahuaca. The Hornocal side trip is unpaved.
• Fuel: Salta (many), San Salvador de Jujuy (many), Tilcara (1-2 stations), Humahuaca (1 station). Fill up before the Hornocal side trip.
• Vehicle: any car for RN 9. High clearance/4x4 for Hornocal.
• Police checkpoints: common on RN 9 near Jujuy and at the province border. Have license, passport, vehicle documents and insurance readily accessible.
• Speed traps: entering and exiting towns. Speed limit drops from 110 to 40-60 km/h — police often position themselves at these transition points.
• Best strategy: either a long day trip (leave Salta by 7am, return by 8pm) or overnight in Tilcara or Purmamarca. The overnight option is far more relaxing and lets you see the golden hour light on the Quebrada.

Route 3: Purmamarca to Salinas Grandes via Ruta 52 — The Salt Flat Crossing

Overview

This 65 km drive from Purmamarca to the Salinas Grandes salt flats is one of the most dramatic ascents in the NOA. In just over an hour, the road climbs from 2,324 m (Purmamarca) to 4,170m (Cuesta del Lipan pass) via a series of spectacular switchbacks, then descends slightly to the salt flats at 3,450m. The Salinas Grandes is a vast, blinding white expanse stretching to the horizon — one of Argentina's most iconic landscapes. The road is fully paved and any car can handle it, though the altitude will affect engine performance on older or underpowered vehicles.

Stage-by-Stage Breakdown

• Purmamarca → Cuesta del Lipan switchbacks (25 km, 30-40 min): the climb begins immediately. The road ascends in dramatic switchbacks carved into the mountainside, with views back down to Purmamarca and the Quebrada that keep getting more spectacular as you climb. Drive slowly and enjoy the views. There are occasional pull-overs for photos. Your ears will pop as you ascend.
• Cuesta del Lipan summit (4,170m): the road levels out at the altiplano. The landscape shifts abruptly from canyon to high-altitude desert — stark, treeless, wind-swept. You may notice breathlessness or a mild headache — this is normal at 4,170m. Keep hydrated.
• Altiplano → Salinas Grandes (40 km, 30 min): flat, straight road across the puna. Look for vicunas grazing on both sides — these elegant wild camelids are common here. The salt flats appear as a white line on the horizon, growing until they fill your windshield. The signed entrance to the Salinas has artisan stalls selling salt carvings and a small parking area.

At the Salinas Grandes

Park at the designated area and walk out onto the salt. In dry season (April-November) the surface is a vast, cracked white plain with geometric patterns. In wet season (December-March) a thin layer of water can create a perfect mirror effect reflecting the sky. Artisans at the entrance sell carved salt blocks and demonstrate the extraction process. Spend 30-60 minutes at the flats.

Essential items: sunglasses (the glare is physically painful without them), SPF 50+ sunscreen (the salt reflects UV radiation), at least 1 liter of water per person, warm layers (wind at 3,450m is cold even on sunny days). Camera for the infinite white landscape and perspective photos.

Practical Information

• Road surface: 100% paved, good condition.
• Fuel: fill up in Purmamarca or Jujuy before ascending. There is NO fuel between Purmamarca and Susques (another 85 km beyond the salt flats). If continuing to Susques (for the Paso de Jama route to Chile), fill up before the Cuesta del Lipan.
• Vehicle: any car. Note that turbocharged engines perform better at altitude than naturally aspirated ones. Your car will feel sluggish climbing the Cuesta del Lipan — this is normal.
• Altitude: the pass reaches 4,170m. Altitude sickness symptoms (headache, shortness of breath) are possible. The visit is brief enough that serious effects are unlikely for most people. Drink coca tea in Purmamarca before ascending.
• Timing: leave Purmamarca early morning for the best light on the salt flats and to avoid afternoon winds. The return to Purmamarca takes 1-1.5 hours.

Route 4: Salta to Cachi via RP 33 — The Mountain Pass Adventure

Overview

The drive from Salta to the colonial village of Cachi via Ruta Provincial 33 is the NOA's most dramatic mountain pass drive. In 157 km, the road climbs from 1,187m (Salta) to 3,348m (Piedra del Molino pass), descends through the Parque Nacional Los Cardones (a vast forest of giant cardon cacti), and arrives in Cachi at 2,280m — a whitewashed adobe village sitting beneath the snow-capped Nevado de Cachi (6,380m). This route includes the legendary Cuesta del Obispo — a winding mountain road with 21 switchbacks — and passes through the cloud forest before emerging into the high desert. It is one of the most rewarding drives in Argentina but requires attention: sections are unpaved, the switchbacks are steep, and there is NO fuel between Salta and Cachi.

Stage-by-Stage Breakdown

• Salta → Chicoana (38 km, 40 min): paved road through the tobacco-farming valley of Lerma. Flat, easy driving. Chicoana is a small gaucho town — last chance for fuel and a roadside empanada. Fill your tank to the brim here.
• Chicoana → Cuesta del Obispo (20 km, 30 min): the road begins climbing. Paved at first, transitioning to improved dirt road. You enter the Yungas cloud forest — green, lush, misty. The vegetation shifts from subtropical to temperate as you gain altitude.
• Cuesta del Obispo (30 km of switchbacks, 1-1.5h): the famous 21-switchback climb. The road is unpaved but well-graded (maintained by provincial highway crews). It is narrow in places — single-lane with passing points. Drive slowly, use your horn before blind curves. The views back down into the valley are vertiginous and spectacular. At each turn, the landscape shifts — cloud forest gives way to scrubland, then to high-altitude grassland. Guardrails are minimal. If you're uncomfortable with heights and narrow mountain roads, consider taking a tour instead.
• Piedra del Molino pass (3,348m): the highest point on the route. A small chapel sits at the pass. The views are staggering — behind you, the cloud forest drops away into the Lerma valley; ahead, the vast valley of the Valles Calchaquies opens up with the Parque Nacional Los Cardones in the foreground. Stop for photos and a moment of awe. It can be very windy and cold here.
• Piedra del Molino → Recta del Tin Tin (30 km, 30 min): descent into the high desert. The Recta del Tin Tin is a perfectly straight 18 km road cutting through the Los Cardones cactus forest — giant cardon cacti (up to 10m tall and hundreds of years old) line both sides of the road as far as you can see. It looks like a scene from a western. The road here is well-maintained dirt, flat, and easy.
• Recta del Tin Tin → Cachi (40 km, 45 min): the road descends gently through the pre-Andean landscape. The Nevado de Cachi appears ahead — a stunning snow-capped massif that dominates the horizon. Arrival in Cachi: whitewashed adobe buildings, a peaceful plaza, an excellent archaeological museum, and several gourmet restaurants. Cachi is worth at least an overnight stay.

Practical Information

• Road surface: paved from Salta to the base of the Cuesta del Obispo. Unpaved (dirt/gravel, well-graded) through the Cuesta del Obispo and from there to Cachi. A high-clearance vehicle (SUV, crossover, pickup) is strongly recommended. A regular sedan can do it in dry conditions but will suffer on the rougher sections.
• Fuel: fill up in Chicoana (last fuel before Cachi). There is NO fuel along the entire 120 km from Chicoana to Cachi. Cachi has one fuel station but it can occasionally run out of stock. Carry a full tank.
• Season: April-November is ideal (dry, clear). The route can be impassable after heavy rain in January-February (mudslides, washouts). Check road conditions with your hotel or the tourism office before departing in the wet season.
• Driving time: 3.5-4.5 hours without extended stops. Budget a full day with photography stops, the Piedra del Molino pass, and the cactus forest.
• Alternative return: you can return to Salta the same way, or continue south on Ruta 40 to Cafayate and return via Ruta 68 (the "big loop" — see next route).

Route 5: Cachi to Cafayate via Ruta 40 — The Wild Loop

Overview

Ruta Nacional 40 between Cachi and Cafayate is one of the most remote and spectacular stretches of Argentina's legendary Route 40. This 160 km segment traverses the heart of the Valles Calchaquies — a high-altitude semi-arid valley flanked by the Andes on one side and the pre-Andean ranges on the other. The highlight is the Quebrada de las Flechas (Arrow Gorge), where enormous tilted rock slabs jut from the earth at dramatic angles like giant arrowheads. The road is mostly unpaved, and the journey takes 4-5 hours (not counting stops). This is remote, authentic, and visually overwhelming driving.

Stage-by-Stage Breakdown

• Cachi → Seclantas (20 km, 30 min): paved road heading south along the valley floor. Seclantas is a tiny village known for its poncho weavers — you can visit workshops where artisans use traditional looms. Brief stop.
• Seclantas → Molinos (30 km, 45 min): the road transitions to improved dirt. Molinos is a beautiful colonial hamlet with an 18th-century church (the body of the last Spanish governor of Salta rests inside in a remarkably preserved state). The Hacienda de Molinos is now a boutique hotel/restaurant worth a lunch stop. Fuel occasionally available here from small vendors — do not rely on it.
• Molinos → Angastaco (40 km, 1h): open valley driving. Increasingly arid and remote landscape. The road follows the Rio Calchaqui. Occasional river crossings (usually dry or shallow from April-November, potentially problematic in wet season). Small farming communities. No services.
• Angastaco → Quebrada de las Flechas (20 km, 30 min): the approach to the Flechas. Angastaco has a small almacen (general store) for snacks and water but no fuel.
• Quebrada de las Flechas (10 km, 20 min): the climax of the drive. Massive tilted rock formations — some 15-20 meters tall — angle out of the earth on both sides of the road like giant arrowheads or shark fins. The geological forces that tilted these beds 65 million years ago are visible in the angled strata. There are signed pull-overs for photos. This is one of the most surreal landscapes in Argentina — utterly otherworldly.
• Quebrada de las Flechas → San Carlos → Cafayate (40 km, 1h): the road improves. San Carlos is a small town with fuel and basic services. The final stretch into Cafayate is paved. Vineyards appear. Arrival in Cafayate, where you deserve a cold Torrontes after that drive.

Practical Information

• Road surface: approximately 60% unpaved. The unpaved sections are generally well-graded but can be washboarded (corrugated) — unpleasant at speed. After rain, mud and river crossings can make sections challenging. High-clearance vehicle strongly recommended. 4x4 advisable in wet season.
• Fuel: fill up in Cachi before departing. San Carlos (30 km before Cafayate) has fuel. The 130 km between Cachi and San Carlos has NO reliable fuel. Carry a full tank and consider a spare jerry can if your vehicle has a small tank.
• Cell phone coverage: spotty to non-existent between Cachi and Cafayate. Download offline maps before departure (Google Maps or Maps.me). Carry water and basic emergency supplies.
• Season: April-November only. December-March rain can make river crossings impassable and turn the unpaved road into mud. The Quebrada de las Flechas section is particularly vulnerable to washout.
• Driving time: 4-5 hours without stops. Budget a full day with the Flechas, Molinos, and lunch stops.

Route 6: Salta to Iruya — The Remote Mountain Village

Overview

Iruya is one of Argentina's most remote and dramatic villages — a cluster of adobe houses clinging to a steep mountainside at 2,780m, accessible only by a narrow mountain road that descends through a series of hairpin switchbacks from a 4,000m pass. The full journey from Salta is 310 km (6-7 hours driving) and combines RN 9 through the Quebrada de Humahuaca with the final 50 km of RP 13, a steep, narrow, unpaved mountain road with sheer drop-offs and no guardrails. Iruya is worth every white-knuckle moment — once you arrive, you find a village that time forgot, with ancestral Kolla communities, traditional weavings, and views that make you feel like you've reached the end of the world.

Stage-by-Stage Breakdown

• Salta → Humahuaca (260 km, 4h): follow RN 9 through the Quebrada de Humahuaca (see Route 2 above). Paved, straightforward driving. Fuel up in Humahuaca.
• Humahuaca → Iturbe junction (20 km, 20 min): continue north on RN 9 past Humahuaca. The turn-off to Iruya at Iturbe is signed. This is your last connection to the main road network.
• Iturbe → Abra del Condor pass (25 km, 1h): the road climbs steeply on unpaved switchbacks from 3,000m to approximately 4,000m. The surface is dirt and loose rock, narrow (single-lane with rare passing points), and drops sharply on one side. Drive very slowly, use your horn before blind corners. The views of the surrounding peaks are staggering. At the Abra del Condor pass, you cross into a different valley system — the descent toward Iruya begins.
• Abra del Condor → Iruya (25 km, 1h): descent through equally dramatic switchbacks, through a deep, narrow canyon with walls of colored rock rising on both sides. The road is carved into the canyon wall. Occasional stream crossings (normally shallow). The village of Iruya appears suddenly as you round a final curve — perched on a mountainside with the valley falling away below. One of the most dramatic arrivals of any destination on the planet.

Practical Information

• Road surface: paved to Iturbe (RN 9). Unpaved from Iturbe to Iruya — dirt, loose rock, narrow, steep, no guardrails. This is the most challenging road in the NOA for self-driving.
• Vehicle: high clearance essential. 4x4 strongly recommended, especially after rain. A regular sedan should not attempt this road. Some rental agencies prohibit certain vehicles on this route — check your contract.
• Fuel: fill up in Humahuaca. There is NO fuel between Humahuaca and Iruya, and NO fuel in Iruya itself. Ensure you have enough for the 100 km round trip from Humahuaca.
• Season: April-November only. The road is frequently closed in January-February due to landslides and flooding. Do NOT attempt in or immediately after heavy rain.
• Alternative: if you don't want to drive, regular minibuses run from Humahuaca to Iruya (3 hours, ~$5 USD). The drivers know the road intimately. This is a sensible option if you're uncomfortable with the conditions.
• Overnight: plan to stay at least one night in Iruya. The village has basic but charming hostels and guesthouses. The sunset and sunrise views alone justify the overnight.

Car Rental in Salta — Everything You Need to Know

Agencies and Rates

Salta has both international agencies (Hertz, Avis, Budget, Europcar) and local ones (MoviTrack, NoaNorte, Salta Rent a Car). International agencies offer more reliability and better insurance; local agencies often have lower base rates but may have older vehicles. Rates:

• Compact car (VW Gol, Fiat Cronos): $35-50 USD/day
• SUV/crossover (Renault Duster, Toyota Corolla Cross): $60-90 USD/day
• 4x4/pickup (Toyota Hilux, Ford Ranger): $90-130 USD/day

Book at least 2 weeks ahead, and earlier for July (winter holidays) and Easter. Automatic transmission is limited — book very early if you need it. Most agencies are at the airport and in the city center. Pick up at the airport on arrival for convenience.

Which Vehicle to Choose

• Ruta 68 + RN 9 + Ruta 52 only: any car. A compact is fine. These are all paved.
• Adding RP 33 (Salta-Cachi): upgrade to a crossover/SUV with good ground clearance. A Renault Duster or equivalent is the sweet spot — affordable, high clearance, and capable on dirt roads.
• Adding Ruta 40 (Cachi-Cafayate) or Iruya: SUV minimum. For Iruya in particular, a 4x4 pickup (Toyota Hilux) is ideal.

Important Rental Considerations

• Insurance: take the full coverage (CDW + theft + third-party liability). Gravel roads chip windshields and paintwork. Without full coverage, you'll pay for any damage.
• Mileage: some agencies offer unlimited mileage; others cap at 200-300 km/day. For the NOA, you need unlimited mileage — a Salta-Cafayate-Cachi loop alone is 500+ km.
• Spare tire: verify the vehicle has one and that it's properly inflated. Flats on unpaved roads are common. Also check for a jack and wrench.
• Child car seats: available but limited — reserve when booking, not at pickup.
• Cross-border: most agencies prohibit taking the vehicle to Chile or Bolivia. If you plan to cross to Atacama, check with the agency specifically.
• Documents: you need a valid driving license, credit card for the deposit, and passport. An International Driving Permit (IDP) is technically recommended though not always checked. Get one before you travel to be safe.

Fuel Strategy — The Critical Guide

Running out of fuel in the NOA is a real risk if you don't plan. Some stretches have 130+ km with no fuel station. Here is the master fuel map:

Golden rule: start every route segment with a full tank. If you're doing any unpaved route (RP 33, Ruta 40, Iruya), fill up at the last available station and carry water and basic emergency supplies.

General Driving Tips for the NOA

• Headlights on at all times: mandatory on all Argentine highways, day and night. You will be fined if caught without them.
• Horn before blind curves: on mountain roads (Cuesta del Obispo, Iruya road), honk your horn before every blind curve. Oncoming traffic may be in your lane.
• Livestock on the road: goats, sheep, llamas and cows frequently cross or stand on roads, especially in the Quebrada and on Ruta 40. Drive slowly near settlements.
• Altitude affects your car: naturally aspirated engines lose roughly 3% power per 300m of altitude. At 4,000m, your car has about 40% less power than at sea level. Don't be alarmed — just use lower gears on climbs.
• Unpaved road technique: lower your tire pressure slightly (from 35 PSI to 28-30 PSI) for better grip on gravel. Drive at 40-60 km/h — too fast causes skidding; too slow on washboard makes you bounce. Avoid sudden braking or sharp steering inputs.
• River crossings (Ruta 40): stop and assess depth before crossing. Walk through if needed. Cross slowly in low gear. If the water is above your tire centers, do not cross.
• Night driving: avoid it outside Salta city. Unlit roads, livestock, and potholes make night driving dangerous.
• Police checkpoints: be polite, have documents ready. Officers occasionally check for warning triangles and fire extinguisher (legally required but rarely enforced for tourists).
• Offline maps: download Google Maps offline maps for the entire Salta and Jujuy provinces before leaving your hotel. Cell coverage is non-existent on remote stretches.
