Jathi Qullu, Mountain summit in Yanacachi Municipality, Bolivia

Jathi Qullu is a mountain summit in the Cordillera Real range of the Bolivian Andes, reaching 5,421 meters above sea level. The peak stands northeast of La Paz within the Yanacachi Municipality, dominating the surrounding alpine terrain.

The name comes from the Aymara language, where 'jathi' means heavy and 'qullu' means mountain. This naming reflects how Andean communities have long connected their language to the physical landscape around them.

The name Jathi Qullu comes from Aymara: jathi means heavy and qullu means mountain, so it is the "heavy mountain". The sources also record the spellings Hati Kkollu, Hati Kollu, Jathi Khollu and Jati Qollu, a sign of how Aymara place names are written differently in Spanish and Aymara orthography.

Reaching the summit requires proper acclimatization since the peak sits above 5,400 meters. Before attempting any established hiking routes, check weather conditions and bring sturdy gear suitable for alpine conditions.

The Aymara name Jathi Qullu means "heavy mountain", from jathi (heavy) and qullu (mountain). Sources also record the spellings Hati Kkollu, Hati Kollu, Jathi Khollu and Jati Qollu, a reminder that Aymara place names reach written form through several transcription conventions.
