Guajará-Mirim

Guajará-Mirim sits on the Mamoré River border and extends across a large area of western Brazil. The municipality is surrounded by protected natural areas, including the Traçadal Biological Reserve, which shapes the landscape around it.

The Madeira-Mamoré Railway, completed in 1912, made this settlement a key connection point between Brazil and Bolivia. The railway marked a turning point for linking this border region to wider commerce and transport networks.

The city serves as a meeting point between Brazilian and Bolivian communities, where daily cross-border interactions shape daily life. People from both sides use the river crossing to trade and connect, giving the place a distinctly binational character.

The dry season offers the most accessible travel conditions for getting around and exploring the surrounding areas. Visitors should prepare for tropical weather and may want to arrange local guides to navigate the protected zones effectively.

A free trade zone established in 1993 opened the city to regional commerce in rubber, timber, and palm oil. This trading area attracts merchants from both sides of the border and shapes the economic character of the place.
