Zapaleri Mountain
Volcanic mountain marking Bolivia–Chile–Argentina tripoint
Zapaleri is a high Andean volcanic cone at the Bolivia-Chile-Argentina tripoint; mountaineers and overland travellers visit for high‑altitude puna landscapes, remote trekking and geological interest.
Zapaleri is a volcanic mountain that marks the tripoint where Argentina, Bolivia and Chile meet in the Central Andes. The summit and its immediate surroundings form a border landmark in a high-altitude puna landscape.
The peak lies in a remote Andean setting and is visited mainly by those undertaking border treks or regional high-altitude routes rather than by general tourists. Routes to the area cross high plateaux and volcanic terrain typical of the triple-border zone.
Geographically it sits on the convergence of national boundaries in the western part of the Altiplano, in the Andean region where the three countries’ frontiers intersect.
- Tripoint location: Marks the tripoint where the borders of Argentina, Bolivia and Chile meet in the Central Andes, making it of interest to border hikers and regional mapping.
How to Get to Zapaleri#
Access approaches differ by country. Travelers typically organize logistics through regional hubs (e.g., Potosí in Bolivia or San Pedro de Atacama in Chile) and arrange cross-border permissions if attempting the precise tripoint. High-clearance vehicles and experienced local guides are strongly recommended.
