# Picada 108: Where the Chaco Swallows the Unprepared
Deep in the heart of the Gran Chaco lies Picada 108—a raw, unforgiving 212-kilometer (131-mile) corridor that cuts through one of South America's most remote wilderness areas. This isn't your typical highway; it's a "picada," a narrow dirt track originally carved through dense scrubland for military or oil exploration, linking Mariscal Estigarribia in Paraguay all the way to the Bolivian border via Mayor Pablo Lagerenza.
Welcome to the Northern Chaco: brutally hot, impossibly isolated, and absolutely relentless. The landscape is a maze of thorny scrubland where the horizon stretches endlessly and civilization feels like a distant memory. Temperatures regularly exceed 40°C, and the closest gas station? You left it hours ago.
Here's where things get real: the road itself is pure gravel and talcal—fine dust that hides deep ruts and vicious rocks. During the dry season, visibility drops to nearly zero in a dust cloud. But rain? That's when Picada 108 transforms into a muddy nightmare. The clay-heavy soil becomes impassable quicksand, trapping even heavily equipped 4x4s for days. Creek crossings appear without warning, turning sections into temporary rivers that can force complete closures.
Expect a full day of driving—minimum—at crawling speeds. There are zero amenities out here: no towns, no fuel, no repair shops. Every kilometer demands your full attention to avoid "guadales" (hidden pockets of deep mud and dust) that'll high-center your vehicle in seconds.
This is expedition territory, not a casual road trip. Bring 400 kilometers worth of fuel, 20 liters of water per person, two full-size spares, a high-lift jack, and sand ladders. Your phone won't work; you'll need a satellite messenger. Never go alone—travel in at least two vehicles. Check the weather obsessively; if rain is forecast, don't even think about entering. And before you depart, notify the local police—this is border country, and you'll need your papers in perfect order.
The Chaco doesn't forgive mistakes. Respect it, prepare thoroughly, and you'll experience one of the world's most extreme road journeys.

extremeCruce de los Andes-Paso de los Piuquenes
🇦🇷 Argentina
Okay, adventure seekers, let's talk about the Cruce de los Andes Paso de los Piuquenes, nestled high in the Argentinian Andes, in the province of Mendoza! This pass hits a whopping 4,350m (14,271ft) above sea level, so get ready for some serious altitude! The road? Well, let's just say it's not for the faint of heart. We're talking gravel, rocks, bumps, and maybe a few tippy moments. You'll need a 4x4 and some solid experience with unpaved mountain roads. Forget about this route from October to June, unless you're a fan of impassable conditions (weather depending, of course). It's steep, and the last stretch is more of a hiking path than a road. Keep an eye on the sky – thunderstorms can turn those unpaved surfaces into a 4x4-only zone, or worse. And even in summer, ice and snow can be a factor, so be cautious. This pass, also called Portillo Argentino, connects Tunuyán in Argentina with San Gabriel in Chile. But a word of warning: if you have respiratory issues or heart problems, this might be one to skip. The air is THIN up there. Altitude sickness is a real concern, and even your engine might struggle with the low oxygen. The summit has about 40% less oxygen than sea level, making breathing a chore. Your pulse will be racing, and even simple movements will feel harder. This high altitude, combined with the unpredictable weather and steep grades, makes this pass a challenging but rewarding adventure.
moderateRoad R-925-S
🇨🇱 Chile
Okay, adventure seekers, listen up! If you're anywhere near Chile's Araucanía Region, you NEED to experience the R-925-S. We're talking about a seriously scenic route nestled at the foot of the Andes, right in the heart of Conguillío National Park. This isn't your average Sunday drive, though. The road stretches for about 65 kilometers of raw, unadulterated beauty—think gravel and black sand under your tires. Expect stunning vistas at every turn, but keep your eyes peeled and hands steady on the wheel. The elevation will give you that high-mountain thrill. Be prepared for a ride that’s as challenging as it is rewarding. It’s a true feast for the eyes and a test for your adventurous spirit!
moderateA challenging unpaved road to Abra Falda Cienaga
🇦🇷 Argentina
Alright, adventure seekers, buckle up for Abra Falda Cienaga in Argentina's Catamarca Province! This baby tops out at a whopping 4,436 meters (14,553 feet), so get ready for some thin air. Also known as Abra Puntas Gordas, this isn't your Sunday drive. We're talking Ruta Provincial 43 (RP43), and "unpaved" is the name of the game. Seriously, you'll NEED a 4x4 for this one. Heights not your thing? Maybe grab a travel magazine instead. The stretch from Salar del Hombre Muerto to Antofagasta is rough, with plenty of sand and washboard sections to keep you on your toes. Perched high in the northwest, some sections are being upgraded with asphalt. Word on the street is the south side descent is smoother sailing. Get ready for some insane scenery!
moderateWhere is Kahuish Tunnel?
🇵🇪 Peru
Cruising through Ancash, Peru? You HAVE to check out the Tunel de Kahuish! This baby sits at a whopping 14,816 feet above sea level, making it one of the highest tunnels on the planet. You'll find it nestled in the northern part of the country, right inside Huascarán National Park in the Cordillera Blanca mountains. Keep an eye out for the awesome Christ statue (Cristo Blanco) overlooking the valley right after you exit. Built as part of a big road project that kicked off way back in 1927, constructing this tunnel was no joke! Lots of dynamite and some serious risks went into blasting through the rock. Finally completed in 1941, it got a facelift in 2007. The AN-110 highway runs right through it, connecting Huaraz and Chavin. It carves its way through the valley of the Santa River, over the Cordillera Blanca, and down to the Marañon valley. Expect pavement on the west side of the tunnel, but things get a little more rugged with mostly unpaved sections on the east side. At 1,587 feet long, this unlit tunnel marks the highest point of the main road and is one of the longest in the country. Cyclists, be warned: there’s no alternate route, you have to go through the tunnel!
