Ticlio Pass (also called Abra Anticona) is a high mountain pass at an elevation of 4,818m (15,807ft) above the sea level, located in the Cordillera Central of the Peruvian Andes. The pass is said to be, incorrectly, the highest paved road in South America and it's traversed by paved Carretera Central Ruta 22, between Lima and La Oroya.
The surface of the road is asphalted, and chains or snow tyres can be required throughout the year. Potentially you’ll be dodging giant boulders falling from above, but the view at the end of the paved road is worth nearly dying for. The pass lies at km 171 just on the Pacific side of the Andes watershed, in the Morococha District in the Yauli Province of Peru. The road is absolutely rammed with trucks and coaches. It’s a deathtrap for cyclists – avoid at all costs!
This road is usually open all year, but it can be closed anytime when the access is not cleared of snow. This hairy drive sweeps through the Andes and has prayer-inducing bends, suicidal wild lamas darting out of the scenery and mountains prone to landslides.
The pass is also known as Nevado de Ticlio. The climb is simply terrible, with a notorius lack of oxygen that tests the organisms and a high degree of steepness. Most people feel altitude sickness at around 2,500-2,800 meters. Near the pass, oxygen is in short supply. The summit marks the border between Lima province and Junin region, and the Continental Divide of South America.
