Cerro Pabellón is a high mountain pass at an elevation of 4.647m (15,246ft) above the sea level, located in the Atacama Desert, in the Ollagüe district, Antofagasta region, in Chile.
The road to the summit is gravel. 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. Don’t forget water, food, extra fuel, a warm jacket, a good GPS and maps. At the summit there is a geothermal power plant composed of two units each with an installed capacity of 24 MW. The surface isn’t great and there are some really steep sections. Located in the Andean Highlands 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 summit, oxygen is in short supply.
