Driving the wild 100km road to Portezuelo Maricunga in the Atacama Desert
Portezuelo Maricunga is a high mountain pass at an elevation of 4,133m (13,559ft) above sea level, located in the heart of northern Chile’s Atacama Desert. Situated within the pristine Nevado Tres Cruces National Park, this pass is a gateway to some of the most dramatic and isolated landscapes in the High Andes.
The environment at Portezuelo Maricunga is one of extreme contrasts. Daytime temperatures can soar up to 30 °C, while at night, the mercury drops drastically, often falling well below freezing point during the winter months. The area is also notorious for its fierce, relentless winds that sweep across the salt flats and volcanic peaks of the Atacama, adding another layer of difficulty to any expedition in this remote region.

How is the road to Portezuelo Maricunga?
The journey to the summit is a true long-distance desert expedition. Starting from La Puerta, the road to the top spans a grueling 100 km (62 miles). The route, officially designated as C-601, consists primarily of loose gravel and deep sand. As you approach the highest point of the pass, the track becomes increasingly technical, featuring 8 sharp hairpin turns that climb steeply through the thin Andean air. Due to the extreme isolation of the area, drivers must be fully prepared for a self-sufficient journey, as there are no services or help for tens of miles in any direction.
What are the main hazards on Route C-601?
Driving to Portezuelo Maricunga is not without its risks. The sandy surface of Route C-601 can become extremely muddy and slippery after the rare desert rains, making it nearly impossible to maintain traction. During and after a storm, the road can become completely impassable, even for the most capable four-wheel-drive vehicles. Beyond the terrain, the high altitude and the lack of oxygen can lead to altitude sickness and reduced engine performance. It is essential to carry extra fuel, plenty of water, and reliable satellite communication, as this is one of the most remote "high roads" in northern Chile.
