Cerro Chajnantor is a high mountain peak at an elevation of 5.635m (18,487ft) above the sea level, located in the high Atacama region of northern Chile. It’s one of the highest roads of South America.
The road to the summit is gravel and pretty rough. 4x4 vehicle recommended. The zone has an exceptionally arid climate, inhospitable to humans. Located in the Atacama desert of Chile, at the summit there’s a 6-meter (20 feet) diameter telescope. At this elevation it’s the highest astronomical site in the world. The high elevation with its risk of altitude sickness, weather concerns, steep road grade, and overall inaccessibility make the journey dangerous and summit trips difficult. It’s a truly unique and unusual place on a lunar landscape. Make sure you get your vehicle and yourself well-prepared before driving this road. Never underestimate this track!
The road to the summit was built in April 2006. It’s one of the highest roads of the country. 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.
