moderateWhere is Salar de Maricunga?
🇨🇱 Chile
Okay, picture this: you're cruising through the Atacama Region of Chile, heading towards this unreal, dazzling white salt flat called Salar de Maricunga. This place is seriously high up, like 3,700m (12,139ft) high! It's in the Nevado Tres Cruces National Park, way out east. The air is super dry, and the temperature swings are wild – scorching hot in the daytime sun, then freezing cold at night. Why should you go? Well, besides the fact that it’s absolutely stunning, this salt flat is loaded with lithium. It's the southernmost of Chile's huge salt flats. The road there? It's Ruta 31-CH, about 280 km (173 miles) of mixed adventure. You'll find some smooth paved sections on either end, but the middle is all gravel, so keep your eyes open. It runs all the way from Copiapó to the Argentinian border. Most of the time, a 2WD car can handle it. Get ready for some seriously epic scenery.
hardHow to drive the steep 4x4 road to Alto de Salinas in Ecuador?
🇪🇨 Ecuador
Alto de Salinas in central Ecuador is not just a road—it’s an Andean adventure reaching a dizzying 4,344m (14,251ft)! Forget the tourist traps; this is a raw, unfiltered dive into the heart of Bolívar province. This high-altitude lifeline links Salinas de Guaranda (aka Salinas de Tomabela), a village famed for its salt, to the even higher alpine plateaus. Think windswept grasslands and an ever-present, mysterious mist—a taste of the wild Ecuadorian paramo. Ditch the Pan-American Highway for a real glimpse into the volcanic soul of the Andes. This isn't your Sunday drive. From Salinas de Guaranda heading east towards Route 491, it’s 16.6 km (10.31 miles) of pure off-road grit. We’re talking loose gravel, dirt, and some seriously steep sections—some ramps clock in at an intense 18% grade! A 4x4 isn't just recommended; it's practically essential to conquer this beast. The weather here has a mind of its own. Even when it's supposedly dry season, expect fog, rain, and mist. Temperatures plummet as you climb above 4,300 meters, often flirting with freezing. The combination of altitude, insane inclines, and poor visibility makes this one of the toughest drives around. Be prepared for anything—heavy rains can turn this track into a slippery, muddy mess in minutes!
moderateAn exciting drive to the top of Abra Malaga Pass
🇵🇪 Peru
Alright, adventure junkies, buckle up for Abra Malaga, a sky-high pass in Peru's Cusco Region that'll steal your breath (literally, it's at 14,248 feet!). We're talking Ruta 28B, a 75-mile ribbon of asphalt stretching from Ollantaytambo to Santa Maria. This isn't just any drive; it's a visual feast. Picture this: leaving the charming Inca town of Ollantaytambo behind, the road begins its ascent, twisting and turning through hairpin after glorious hairpin, each revealing a more jaw-dropping panorama of the Sacred Valley. But hold on tight, because the eastern descent plunges you into a mystical "neblina" zone – think rugged terrain, ethereal mist, and windswept grasslands. Now, a word of caution: those stunning Andean peaks can be fickle. Autumn and winter bring snow, often shutting down the road completely, and icy conditions make it a slippery gamble. So, plan accordingly! With over a hundred hairpin turns and some seriously steep sections, it’s not for the faint of heart, but the dramatic landscapes? Totally worth it. This drive is a pure shot of Peruvian beauty straight to the soul.
hardWhere does Road 34H lead?
🇵🇪 Peru
Way up in the Sandia Province of Peru's Puno Region, you'll find one wild ride on the road from Quiscupunco to Sandia. Think of it as a real-life roller coaster through the Andes! This high-mountain pass stretches from Quiscupunco to the town of Sandia, and it's not for the faint of heart. You'll be conquering the legendary Abra Sandia pass and catching glimpses of the stunning Laguna Saytococha. Heads up: this route heads south-to-north, diving from the high Altiplano into those deep, humid Amazon valleys. The trickiest part? Definitely between the Abra Sandia summit (also called Abra Apacheta) and Laguna Saytococha. This is serious frontier territory near Bolivia, with crazy vertical drops, skinny canyons, and rivers that love to wash out the road. Okay, so some of this road is paved, but don't get too excited. That pavement is narrow and beat-up, winding through a barren landscape where the mountainside looks ready to slide onto you at any moment. Flash floods, avalanches, and landslides are common, so expect plenty of stretches of raw gravel and mud, totally out of the blue. And get this – the road is super narrow. If you meet a truck on a blind turn, someone's backing up for miles along a cliff edge. High-clearance vehicles are a must, and driving in the wet or dark? Forget about it. The biggest danger is, well, the insane drop-offs. The road hugs the edge of massive slopes without guardrails. Look over your shoulder and it's a straight shot into valleys thousands of feet below. Plus, expect heavy mist and sudden fog that can cut visibility to nothing. The hairpin turns alone will make you dizzy, and the steep descent will test your brakes big time. At almost 15,000 feet, altitude sickness is real. Nausea and dizziness are common. Don't overeat before the climb, or you might be making a roadside deposit. And your mechanical skills need to be on point. You need to be confident reversing on those narrow shoulders and managing low gears on steep descents. Help is non-existent out here, and a breakdown could mean a long fall. Always pack emergency supplies, extra fuel, and make sure your tires are ready for both wet asphalt and jagged gravel.
