Year-round
Deep in Chile's Atacama Desert, perched at 2,380m (7,810ft), sits Cerro Las Campanas – home to one of the world's top spots for stargazing, the Las Campanas Observatory!
The adventure starts off Ruta 5 (the Pan-American Highway), somewhere between Vallenar and La Serena. From there, it's a 39.6 km (24.6 mile) journey snaking through the stark, stunning Atacama landscape. Think vast, empty desert dotted with more telescopes than people. The observatory is a modern marvel, but the road getting there? Pure, unadulterated desert solitude.
The road's a bit of a mixed bag – some paved sections, some not. It's generally kept in decent shape for those huge telescope components, but expect some dusty, gravelly patches. Oh, and it's steep! You'll climb a hefty 1,325 meters. The real kicker? "Camanchaca" – thick, dense fog rolling in from the Pacific, slashing visibility and making those steep drop-offs seriously hairy.
Don't underestimate the weather. At that altitude, it's intense! Wild winds whip across the ridges year-round, and winter temps are brutal. Even summer can bring surprise snowstorms. The road can shut down at any moment thanks to snow or ice. If it’s snowy or stormy, seriously reconsider driving. Slick roads + steep slopes = a bad combo in the middle of nowhere.
The summit is a scientific wonderland, packed with optical and solar telescopes, including the famous Magellan telescopes. It's a working observatory, so there are basic amenities for the staff, but be aware of traffic. Big service vehicles use this narrow road, and it can be tough to hear them coming. Pick your lines wisely and use those low gears on the way down – that 3.34% average gradient can really test your brakes!

hardDriving the Challenging AN 104 Road to Chicarhuapunta
🇵🇪 Peru
Okay, adventure junkies, listen up! You HAVE to add Chicarhuapunta to your bucket list. This insane mountain pass tops out at a dizzying 14,071 feet in the Peruvian Andes – yeah, you're gonna feel that altitude! You'll find it deep in the Cordillera Blanca range, in the Ancash Region of western Peru. Now, let's be real: getting there is half the battle. Carretera 104 (or AN 104, if you're feeling official) is a beast. Think narrow roads, both paved and unpaved, with zero guardrails protecting you from some seriously scary drop-offs. We're talking over 300 turns, with around 100 of those being hairpin bends. Clutch those rosaries, people! The whole route stretches for 88 miles between Pueblo Libre and Huambacho, going from east to west. And did I mention steep? The climb from Tocash is a leg-burner – almost 2,000 meters of elevation gain over just 32.6km. That's an average gradient of nearly 6%, but be prepared for sections that hit a whopping 12%! But trust me, the views are worth it. The raw, untamed beauty of the Cordillera Blanca will take your breath away (if the altitude doesn't first!). Just take it slow, stay focused, and prepare for the drive of your life!
hardWhy is Termas Valle de Colina famous?
🇨🇱 Chile
Okay, picture this: you're in Chile, itching for an adventure, and someone whispers about natural hot springs nestled high in the Andes. That's Termas Valle de Colina, sitting pretty at 2,500 meters! Getting there is half the fun. You'll cruise from Santiago for about 76 kilometers (almost 50 miles!) towards Argentina, following Camino Al Volcán (Ruta G-25). The road hugs a river, snaking its way deeper and deeper into the mountains. It's paved at first, but don't get too comfy. The last 10 kilometers are rocky, unpaved, and begging for a 4x4. Seriously, leave the sedan at home. Expect some steep sections! Once you arrive, it's a short 3-kilometer hike to a killer viewpoint of the San José Volcano. But the real reward? Nine natural thermal pools, terraced down the mountainside, with water temps hitting up to 50°C. Imagine soaking in those mineral-rich waters with snow-capped peaks all around – bliss! Word to the wise: check the weather. Even in summer, it can get chilly up there, especially at night. The weather can change fast, from sunny skies to misty rain, or even snow. In winter, the road's usually closed, so plan accordingly. This isn't just a drive, it's an experience!
hardSC-390 is a Brazilian ludicrously zigzagged road in Serra do Rio do Rastro
🇧🇷 Brazil
# SC-390: Brazil's Epic Mountain Zigzag Ready for one of the world's most thrilling drives? SC-390, also known as Rodovia Daniel Brüning, is a jaw-dropping roller coaster of a road that winds through the mountains of southeastern Santa Catarina, Brazil. Built way back in 1903, this legendary route has earned its reputation as one of the most famous hairpinned roads on the planet. Nestled in the Serra do Rio do Rastro mountain range near Lauro Müller, this beast of a road climbs to a dizzying 1,465m (4,806 feet) above sea level. The whole stretch spans just 12.87 km (8 miles), but don't let that fool you—you'll navigate a mind-bending 250 corners while dropping from nearly 4,800 feet to sea level. With an average gradient of 9.2%, it's an adrenaline-pumping adventure that demands respect and concentration. The scenery? Absolutely stunning. On clear days, you can spot the Atlantic Ocean from up here, roughly 100 km away. The landscape is pure magic: tumbling waterfalls, dramatic canyons, pristine lakes, cascading rapids, and lush native wildlife make this one of Brazil's most gorgeous regions. The road is fully paved and impressively lit by massive windmills that line the route. This region has a distinctly European vibe—thanks to German and Italian settlers who colonized the area centuries ago. You'll spot charming German-style architecture and notice the fair-skinned locals. The climate here is surprisingly temperate despite the altitude, with annual temperatures averaging around 12°C. Planning a visit? Go between December and March when summer skies are clearest. Winter fog can be a real headache, though you might encounter some cloud coverage even in summer when cold fronts sweep in from the south. Traffic is blessedly light, so you can really take your time and soak in those jaw-dropping views.
extremeHow Long is the Road from Pusac to Uchumarca?
🇵🇪 Peru
Okay, thrill-seekers, buckle up for the Púsac-Uchumarca road in the Bolívar Province of northern Peru! This isn't your average Sunday drive. Starting in Púsac at 1,434m above sea level, you'll climb to a dizzying 3,684m as you approach Uchumarca. This 34.1 km (21.18 miles) unpaved road is carved into the side of a seriously steep mountain. Translation: narrow, winding, and exposed – think hundreds of meters straight down with zero guardrails. Hope you're not afraid of heights! The real test is "Cuesta de Uchumarca," a heart-pounding 4.9 km (3 miles) stretch boasting 16 hairpin turns! You'll gain 454m in elevation with gradients hitting up to 15%. But hey, the views are absolutely epic. Just be sure to check the weather forecast before you go; you don't want to be tackling this beast in bad conditions!
