Hornocal Tours & Tickets

Hornocal's 14-Color Mountain (Serranía del Hornocal) displays its most vivid mineral-striped palette between April and October when mineral oxidation is most visible.

The mountain sits at 4,895 metres (16,050 feet) elevation in Jujuy Province, making it one of Argentina's highest tourist-accessible peaks.

Hornocal village itself has fewer than 100 permanent residents and relies almost entirely on trekking tourism for its economy.

The 14 distinct colour bands—including reds, purples, yellows, and greens—are created by different mineral deposits (iron oxide, copper, sulphur) rather than paint or artificial treatment.

A full trek to the summit takes 8–9 hours round trip on foot, with the final 3 km being the steepest and most colourful section.
