Alto de Letras is a rite of passage for Colombian cyclists, both amateur and pro, and a legendary stage in the Vuelta a Colombia. Starting in the subtropical heat of San Sebastián de Mariquita at 468 meters and ending in an arctic climate at 3,692 meters, it's truly a once-in-a-lifetime cycling experience.

extremeWhen was Vetas founded?
🇨🇴 Colombia
Okay, buckle up, adventure awaits! We're headed to Vetas, Colombia, rumored to be the highest town in the whole country, perched way up at 3,350 meters (that's nearly 11,000 feet!). Founded way back in 1551 amidst a major mining zone, getting here is half the fun. Forget smooth asphalt, this is an unpaved, 21.8 km (13.54 miles) rumble starting from Berlin on the Bucaramanga-Pamplona road (66). A 4x4 isn't just recommended; it's practically essential! The climb is seriously intense, the air gets thin, and the gravel can be super loose, especially near the edges. Trust me, this isn't a Sunday drive. This remote route climbs thousands of feet through seriously isolated landscapes, often shrouded in mist. Make sure you're prepped for a real adventure because the views? Totally worth it.
hardA hairpinned paved road across Chicamocha Canyon in Colombia
🇨🇴 Colombia
Okay, adventurers, buckle up for the ride of a lifetime across Colombia's stunning Cañón del Chicamocha! Tucked away in the Andes, straddling Boyacá and Santander departments, this canyon is a beast—some say it's the second-biggest on the planet, plunging a whopping 6,600 feet deep! You'll find this paved beauty, Ruta Nacional 45A, winding through Chicamocha National Park (aka Panachi). But don't let the pavement fool you – this toll road is a proper challenge. Think seriously steep sections and more twists and turns than you can count! This north-south rollercoaster stretches for about 25.5 miles (41 km) from Los Curos to Aratoca. Get ready for some breathtaking scenery, just be sure to keep your eyes on the road!
hardCurvas de Huanchaca: 24 Switchbacks on a Narrow and Steep Road
🇵🇪 Peru
Get ready for the Curvas de Huanchaca, a wild ride through the Peruvian Andes! This road, snaking along the border of Cusco and Apurimac, is famous for its mind-boggling series of 24 hairpin turns. Seriously, it's one of the most intensely switchbacked roads on the planet, promising a drive that's both spectacular and maybe a little dizzying. You'll find this beauty in the southern highlands of Peru, nestled in the Urubamba Valley, about 40km west of Cusco. It's known locally as Curvas de Huallpachaca too. Route 3SF has been recently paved and even though it's barely wide enough for one car in places, most vehicles can handle it. But don't let the fresh pavement fool you – this road is a challenge! Those 24 switchbacks are carved right into the rock, and there are no guardrails to keep you from the sheer drop-offs. If you're not a fan of heights, maybe focus on the road ahead! This incredible feat of engineering climbs steeply through the mountains, maxing out at a 17% gradient in some sections. The intense part is 12.5km (7.76 miles) long, starting at the Puente Huallpachaca over the Apurimac river at 2,142m (7,027ft) above sea level and topping out at 2,901m (9,517ft) asl. That's a whopping 759 meters of elevation gain, averaging out to a 6.07% gradient. Trust me, you'll feel it!
hardEl Angosto
🇦🇷 Argentina
Okay, adventure seekers, listen up! I just discovered the coolest, most challenging route in the Jujuy province of Argentina: El Angosto! This isn't your average Sunday drive. Picture this: you start in Santa Catalina, cruising along a decent gravel road that leads you straight into the mountains. El Angosto itself is perched way up high at 3,581 meters (that's 11,748 feet!). But that's not all, folks! The road then just keeps climbing, pushing you up to an unnamed mountain pass at a lung-busting 4,180 meters! Seriously, the air gets THIN. Be prepared for a test of your endurance, and maybe pack some altitude sickness remedies. The gravel surface can be loose, especially near the edges, so stay alert. And if it's been raining? Forget about it! This track turns into a muddy, slippery mess that even 4x4 vehicles might struggle with. Seriously, if the weather looks bad, just don't go. But if you time it right? The views are supposed to be incredible. This is an old mining road near the Tuzgle Volcano in the Andes, and well worth the challenge, if you are prepared!
