Cerro Rincón, Mountain peak in Misiones Province, Argentina
Cerro Rincón is a mountain peak in the Sierra de Misiones near the Brazilian border in Misiones Province. The mountain is part of a forested range with several trails that lead through dense vegetation typical of the subtropical region.
The mountain served as a natural boundary marker between Argentina and Brazil from the late 19th century territorial agreements onward. This geographic role established it as a key reference point in the region's development.
The Guarani communities in this region view the mountain and surrounding forests as central to their traditional maps and stories. This connection to the land remains visible today in how people move through and understand the area.
The best hiking conditions are from April to October when weather is more stable and trails are easier to navigate. Several routes connect from nearby towns, but sturdy footwear and some experience with mountain terrain are helpful.
On clear days, visitors can see three countries at once from the summit: Argentina, Brazil, and Paraguay. This view is a memorable reward for the climb and reflects the mountain's unique border location.
