Abra Oquepuño is a high mountain pass at an elevation of 4.873m (15,977ft) above the sea level, located in the province Carabaya in the region Puno, in southern Peru. It’s said to be the second highest asphalted road in South America.
The pass is traversed by the Carretera Interoceanica, also known as Ruta nacional PE-34B. It’s an asphalted road. Do not take this drive if you have respiratory problems or any type of heart condition. 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. Extremely low oxygen for engine combustion. A major hazard of altitude is the sickness that can indiscriminately affect anyone regardless of age or fitness.
The summit has about 40% less oxygen than at sea level, thus breathing is more difficult. Your pulse rate will increase and movement will be more laborious at the summit. The high elevation with its risk of altitude sickness, weather concerns, steep road grade, and overall inaccessibility make the pass dangerous and summit trips difficult. The pass is located between the towns of Huasara and Trapiche. It has a well-deserved reputation for being dangerous because of unpredictable snowstorms and blizzards, and driving under these conditions, can be extremely challenging.
