The average gradient is around 4%, but don't let that fool you. This is considered the longest road climb in the world. Expect pitches hitting 11% or 12% in places that'll test your legs and lungs.
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.

moderateThe Historic Motorcycle Expedition to Aconcagua with Bultaco Sherpa
🇦🇷 Argentina
Okay, picture this: you're in Argentina, Mendoza Province, staring up at Aconcagua. Not just looking at it from a distance, but imagining yourself *on* it. This giant of a peak clocks in at a staggering 6,961 meters (that's 22,838 feet for those of us who think in freedom units!). Now, I know what you're thinking: "Roads? On a mountain that high?" Yep, and a group of crazy-brave (or maybe just plain crazy!) Spanish motorcyclists proved it back in '77. Riding Bultaco Sherpa T 183s, they climbed to an insane altitude, setting a record for motorcycling outside of Asia. These guys from Moto Igualada weren't messing around. They attacked Aconcagua on two Bultaco Sherpa T 350 cc bikes, fueled by pure ambition. Though they ultimately fell short of the summit, they reached an altitude of 6,800 meters, beating a Kilimanjaro record set just a few years prior. Aconcagua? More like Acon-CAN-gua, right?
extremeWhere is Altos Corvo Branco?
🇧🇷 Brazil
Alright, adventure seekers, listen up! Deep in the heart of Santa Catarina, Brazil, snuggled within the Serra do Corvo Blanco (White Crow's Mountain) range, you'll find Altos Corvo Branco, a mountain pass that'll take your breath away – literally and figuratively! We're talking about an elevation of 1,245m (4,084ft), so expect some serious views. This epic road, known as SC-370 (Estrada da Serra do Corvo Branco), stretches for 67km (41 miles) from Braço do Norte to Urubici, acting as a vital link between southern Santa Catarina and the Planalto Catarinense. Now, don't go thinking this is a leisurely cruise. This drive is challenging! The final 1.6km is a beast, boasting sections with a 30% gradient and five hairpin turns that'll test your driving skills. Think tight curves, narrow stretches, steep drops, and cliffs that plunge dramatically. Trust me, the panoramic views are worth it, but be warned: low gears are your friend here. And if you're tackling this in rain or fog? Maybe reconsider. Definitely not bus or big-rig friendly. Get ready for an unforgettable ride, with viewpoints practically around every bend!

hardAbra Huaytire, an absolute must for road lovers
🇵🇪 Peru

The road, Carretera 36A, is paved the whole way, but don't let that fool you. It's a wild ride of twists, turns, and narrow sections that'll keep even seasoned drivers on their toes.
