Abra Taapaca is a high mountain pass at an elevation of 5.250m (17,224ft) above the sea level, located in the Nevados de Putre volcanic complex, in Chile's XV region of Tarapaca. It's one of the highest mountain roads of Chile.
The road to the pass is gravel. It’s called A-23. According to several sources, the pass could be at 4.802m above the sea level. Starting from the hamlet of Alcerreca, first comes a descent of 350m into the stunning Quebrada Allane, a ford of the river at 3,600m. The last part of the climb is extreme. There are a few steep kilometres. Due its unique location and the climb in elevation over thousands of feet, and passing through remote areas, it is important when driving in these conditions to be prepared. After rain, even a single rainfall, conditions of the road can be challenging. Avalanches, heavy snowfalls and landslides can occur anytime and can sometimes block some sections of the road, being extremely dangerous due to frequent patches of ice. Don’t forget water, food, extra fuel, a warm jacket, a good GPS and maps.
