Paso Guaitiquina
Paso Guaitiquina is a high mountain pass at an elevation of 4.451m (14,603ft) above the sea level located in the Antofagasta Region of northern Chile. 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 road to the summit is gravel. It’s called B-357. This track can get very muddy and slippery after rain making it challenging to get through. During and after a storm the road may be impassable, even with a four-wheel-drive vehicle. Open to all motorized vehicles, however, recommended for high clearance, 4-wheel drive vehicles.
