The Mamoré River is one of the most significant waterways in Bolivia, joining the Beni River to form the Madeira River, the Amazon's largest tributary. Originating in the eastern foothills of the Andes from the confluence of the Ichilo and Grande rivers, it flows for approximately 1,900 kilometers across the vast plains of the Beni Department. The Mamoré is known for its highly meandering course, which continuously creates oxbow lakes and extensive wetlands within the 'Llanos de Moxos' region. This area is ecologically vital, supporting a vast array of wildlife, including the Amazon river dolphin and countless rare bird species. Historically, the river served as a primary transportation route for indigenous cultures and later played a crucial role during the 19th-century rubber boom. Today, it remains an essential corridor for trade and travel connecting remote lowland communities. Along its lower section, the Mamoré defines the border between Bolivia and Brazil for about 265 kilometers before its final confluence.
