Cerro Aucanquilcha is a massive stratovolcano located in the Antofagasta Region of Chile. An old mine road used to run to the top, but now much of it about 5.500m (18,044ft) above sea level has been wiped out by landslides. For many years it
was the highest drivable road in the world
When was the road to Cerro Aucanquilcha built?
Set high in the northern part of the country, part of the Central Volcanic Zone of the Andes,
the road to the summit is totally unpaved, but no longer usable by vehicles. Mining originally began on the volcano in 1913,
initially using llamas as pack animals to carry down the sulfur. An aerial cable system extending for 22 km (14 mi) was completed in 1935, to lower the sulfur in buckets.
Eventually this was replaced in 1972 by the road which switchbacked up to the summit and was capable of supporting 20-ton mining trucks.
It was the world's highest mine during that period. It’s
one of the highest roads of South America
Can you drive to the summit of Cerro Aucanquilcha?
Located to the west of the border with Bolivia, within the Alto Loa National Reserve
one of the highest roads of Chile
This is an extremely tough road to try and climb up on a bike. The terrible surface and steep gradients meant that with loaded bikes you will have to push about 80% of the way from 4,000m to a high point at 5,130m.
Although a number of people have taken their bikes to the summit, the surface on many stretches of the road is very bad or even blocked due to landslides. However, there are sections of rideable road all the way to the summit.
At the summit itself it would also be possible to ride around a bit. Since the mine closed in 1993 much of the road has fallen into disrepair. Motorized use is no longer possible.
How is the climb to Cerro Aucanquilcha?
The existence of the old road makes it relatively easy to get to the summit on foot if you are well acclimatized and the old mining camp at 5,280m makes a good base camp as there are walls to shelter your tent.
The winds in this area can be fierce and especially in winter the nights can be extremely cold. The highest permanent human habitation was a galvanized iron hut acting as a miners' barracks, with 4 workers, at about 5,500 m (18,000 ft).

extremeAbra de la Santa Cruz: Driving the 4,597m Jujuy-Salta Boundary (RP13A)
🇦🇷 Argentina
Okay, adventure seekers, listen up! Wanna tackle a seriously epic road trip? Then you HAVE to check out Abra de la Santa Cruz, a crazy-high mountain pass nestled way up in the Argentinian Andes. We're talking a lung-busting 4,597 meters (15,082 feet!) above sea level, so yeah, it's not for the faint of heart. You'll find this beast straddling the border between Jujuy and Salta provinces in northern Argentina. Route 13A will lead you on this wild, 46-kilometer (28-mile) ride from Abra del Sauce to Casillas. Now, fair warning: this ain't your average Sunday drive. The whole thing is unpaved and throws EVERYTHING at you – think narrow stretches, seriously steep inclines, and more hairpin turns than you can count! A 4x4 isn't just recommended; it's practically essential to conquer the ever-changing terrain of loose gravel and jagged rocks. But the biggest challenge? The altitude! At that height, altitude sickness is a real threat, so come prepared. Also, you're pretty much in the middle of nowhere, so don't expect to find gas stations or emergency services around every corner. Pack extra water, fuel, and a first-aid kit, and ALWAYS keep an eye on the weather forecast, because things can change on a dime up there. But hey, the payoff? Unforgettable, panoramic views of the stunning high-altitude Andes scenery that'll leave you breathless (literally!).
moderateDriving the road to Corazon Volcano is not a piece of cake
🇪🇨 Ecuador
Okay, adventure seekers, listen up! Deep in the Pichincha province of Ecuador, just southwest of Quito, lies Volcan Corazon, an old, snoozing volcano begging to be explored. Forget paved paradise, because you're gonna tackle a gnarly gravel road that winds its way up, up, up to a breathtaking 4,306 meters (that's a staggering 14,127 feet!). Seriously, this is one of Ecuador's highest roads! Forget your fancy sports car; you'll need a 4x4 with some serious clearance for this slow-and-steady climb through the western Andes. Keep an eye on the sky, because those Andean weather patterns are wild! The rainy season often transforms the landscape into a snowy wonderland, but be prepared for anything – and pack warm clothes! Your starting point? The charming town of Machachi. Get ready for views that'll steal your breath (and maybe test your car's limits)!
moderateTravelling through Estrada Santa Cruz do Rio Abaixo
🇧🇷 Brazil
Okay, adventure seekers, listen up! If you're anywhere near eastern São Paulo, Brazil, you NEED to check out Estrada Santa Cruz do Rio Abaixo. This isn't your average drive; it's a 10km off-road escapade that'll get your adrenaline pumping. Picture this: a winding, unpaved path of gravel and sand, climbing to 1,000 meters above sea level. The views? Absolutely stunning! But be warned, this road's not for the faint of heart. When the heavens open up, this area is prone to flash floods, so keep an eye on the weather. You might find yourself wading through water or facing washed-out sections. So, if you're up for a challenge and craving some raw, untamed beauty, this Brazilian backroad is calling your name!
extremeWhere is Carirriñe Pass?
🇦🇷 Argentina
Paso Carirriñe, nestled high in the Andes at 1,150m (3,772ft), marks the border between Chile and Argentina. It's one of those lesser-known routes that's absolutely bursting with beauty! This pass links the Los Ríos region of Chile with the stunning Patagonian landscapes of Argentina. The adventure stretches for 133 km (82.64 miles), from the Chilean town of Coñaripe (right on Lake Calafquén) to San Martín de los Andes in Argentina. Expect seriously amazing scenery! Think hot springs, rivers of solidified lava, and all sorts of evidence of volcanic activity. Heads up: the pass is usually open from November 15th during the summer months, from 8 am to 8 pm. Snow, landslides, and road work can close it for much of the year, though. On the Chilean side (Ruta CH-201), the road's mostly paved but pretty narrow. The final 15km are gravel, but keep an eye out, it might be paved soon. Once you cross into Argentina (Ruta Provincial 62) get ready for a bumpy ride! It's a narrow, unpaved forest road and hasn't been maintained in a while. It's doable, but maybe not in your average sedan. Weather's a big factor here too, especially in winter. Locals with 4x4s use it often, though!
