The challenging 4x4 road to Cerro Tuc Tuc: A high-altitude pass in Salta

Cerro Tuc Tuc, also known as Cerro Tuc Tuca, is a beast of a mountain pass in the Santa Victoria Department of Salta, Argentina. This remote track near the border with Jujuy tops out at a staggering 4,624m (15,170ft) above sea level, making it one of Argentina's highest roads. Get ready for a raw, unfiltered driving experience!

West of the famous Abra Fundición, you'll find this epic route, locally called Camino a Bacoya. Prepare for a dramatic landscape filled with vibrant, colorful mountains and weathered rock formations typical of the high Andean plateau.

Forget pavement – this is a narrow, unpaved dirt and gravel track that demands a high-clearance vehicle. Navigating this road is technical; it's often too narrow for two regular cars to pass without a squeeze, especially where there are those heart-stopping drop-offs!

Starting in Santa Cruz de Aguilar, the road to the summit stretches for 18.66 km (11.6 miles). It's a steady climb of 624 meters. The average gradient is a manageable 3.34%, but the high altitude will test your engine's limits.

A 4x4 is practically mandatory, especially after it rains. The surface can get slick, and the steep sections need serious traction. Remember, you're in a remote area, so being properly equipped is crucial for a safe adventure.

The weather at 4,624 meters is unpredictable. Be prepared for extreme conditions, the notorious lack of oxygen, and the risk of altitude sickness. The combo of steep hills, tight squeezes, and rapidly changing weather demands your full attention.

But oh, the views! The pass offers breathtaking panoramic vistas of the Salta and Jujuy highlands. The colorful mountains all around create a visual feast. This is a must-see spot for overlanders searching for the most isolated and scenic roads in northern Argentina.
