Year-round
Calling all adventurers! Deep in Chile's Atacama Region, near the Argentinian border, lies Cerro Azufrera de los Cuyanos, a massive volcano hiding one of the country's highest roads. We're talking a lung-busting 5,553m (18,218ft) above sea level! This isn't your Sunday drive; this extreme mine road is strictly for seasoned off-roaders and their beastly vehicles.
Starting from Ruta C-173, this 47.1 km trek punches upwards, gaining a staggering 2,060 meters in elevation. Located south of Cerro Piedra Parada, the road relentlessly climbs through the stark Atacama landscapes, culminating in a zone of scarce oxygen and brutal conditions.
Expect a rocky, gravel-strewn surface that will test your mettle. Nearing the summit, brace yourself for 13 tight hairpin turns demanding expert maneuvering. Large, sharp volcanic rocks litter the path, posing a serious threat to your tires. Leave your stock vehicle at home; high clearance, skid plates, and differential lockers are non-negotiable.
The altitude is the ultimate challenge. Above 5,500 meters, the thin air can trigger respiratory problems or exacerbate heart issues. Be prepared for bone-chilling temperatures and relentless winds. The weather is notoriously unpredictable, with sudden snowstorms possible even in summer.
This primitive road, a relic of its mining past, sees little to no maintenance. Given its extreme isolation and exposure, self-sufficiency is key. Pack extra fuel, oxygen, and cold-weather gear. Remember, you're on your own out here in this remote corner of the Atacama – no services or rescue teams to rely on.

hardQuebrada Blanca
🇨🇱 Chile
Okay, adventure junkies, listen up! Quebrada Blanca in Chile's Tarapacá Region is calling your name! This insane mountain pass tops out at a staggering 4,389 meters (that's nearly 14,400 feet!), so get ready for some serious altitude. Nestled deep within the Andes, this isn't your average Sunday drive. Think gravel, rocks, bumps galore – the A-85 road is a real off-road challenge. You'll definitely need a 4x4, and a healthy dose of courage. Seriously, if unpaved mountain roads aren't your thing, maybe skip this one. It's steep, it's high, and if it's wet, it's going to be muddy and tough. Winter? Forget about it, probably impassable. But hey, if you're an experienced off-roader looking for a thrill, this is your playground. The views from up here? Totally worth it.
extremeIs the road to Volcán Ollagüe unpaved?
🇧🇴 Bolivia
Okay, buckle up, adventure junkies! We're heading to Volcán Ollagüe, a beast of an andesite volcano straddling the Chile-Bolivia border at a staggering 5,868m (19,251ft). Forget paved paradise; this road is a raw, unadulterated dirt track clinging to the volcano's northern flank. This extreme, old mine road, once crucial for a now-defunct sulfur mine, is a white-knuckle ride all the way. The trail ends at a breathtaking, but oxygen-deprived, 5,705m (18,717ft). This is strictly 4x4 territory, people! Don't even think about attempting this in anything less. Starting from the humble Chilean village of Ollagüe, the road throws you into a relentless 24.7km (15.34 miles) of pure adrenaline. Hold on tight for 35 hairpin turns that’ll have you questioning your sanity, combined with a seriously steep average gradient of 8.04%. Oh, and did I mention the sheer drops of hundreds of meters with zero guardrails? Yeah, this climb isn't for the faint of heart. Keep a keen eye on the weather! Avalanches, blizzards, and landslides are real threats, especially during January and February's storm season. Speaking of threats, altitude sickness is a major concern. The air's incredibly thin up here (40% less oxygen than at sea level), so if you have respiratory or heart issues, seriously reconsider this adventure. Even the toughest engines struggle with combustion at this altitude, so prep yourself and your vehicle. But here's the payoff: the views. Oh my, the views! You'll be gazing out at landscapes so surreal, so starkly beautiful, they'll be seared into your memory forever. You'll also see persistent steam plume emanate from a fumarole on the south side of the summit dome. Volcán Ollagüe is a challenging, dangerous, and utterly unforgettable experience. Are you brave enough?
hardPaso Cacanapunta
🇵🇪 Peru
Alright, adventure junkies, listen up! Wanna tackle a beast of a pass in Peru? I'm talking about Cacanapunta Pass, chilling way up high in the Ancash Region at a staggering 13,654 feet! This isn't your Sunday drive, folks. We're talking gravel, rocks, bumps, and a whole lotta shaking. Winter? Forget about it – impassable. This one's for the seasoned off-roaders. If you're not comfy on unpaved mountain roads, maybe grab a postcard instead. But hold on, because the reward is HUGE! Picture this: insane, wide-open views of the wild Huayhuash mountains. Seriously breathtaking. 4x4 highly recommended, and if heights aren't your thing, maybe skip this one too. It's STEEP. And when it's wet? Muddy mayhem! Heads up: you're climbing high, so take it easy. The air gets thin, and you'll feel it. Most people start feeling the altitude around 8,200-9,200 feet, and up here near the top, oxygen is scarce. But you know what? It's SO worth it. You'll be straddling the South American Continental Divide, with views of snow-capped peaks like Ninashancaa and Rondoy, plus the stunning Pucacocha Lake. Unforgettable!
hardCan you drive to Sosneado Hotel?
🇦🇷 Argentina
Okay, adventurers, buckle up for a wild ride to the eerie Hotel Termas de El Sosneado! Deep in the Mendoza Province of Argentina, this isn't your typical Sunday drive. Forget pavement, Provincial Route 220 is all about rocks, loose gravel, and maybe a little rubble for good measure. Oh, and did I mention the narrow wooden bridges, mud, and rivers of brown water you'll be splashing through? Starting near El Sosneado, this off-road adventure stretches nearly 60 km to the ruined hotel, perched beside the Atuel River. Trust me, you'll want a 4x4 for this one. You'll climb to over 2,000 meters above sea level! Built in 1938, this luxury hotel met its end after an avalanche in 1953. The main draw? Thermal spring pools fed by the nearby Overo volcano! Word is you can still take a dip. Locals whisper about it being a former Nazi hideout. Spooky, right? Set against the backdrop of the Andes, this trip will steal 2-3 hours of your day. Heads up: this road is usually impassable during winter. There are no services along the way, so pack a full tank of gas, food, and plenty of water. You've been warned!
