The Mamberamo is the second-longest river on the island of New Guinea, after the Sepik River (1,126 km), and the second-largest river in Oceania. It is located in the province of Papua, Indonesia.
The Mamberamo area also broadly refers to several nearby mountain ranges, including the Van Rees and Foja Mountains (also known as Foya), which were the subject of a recent rapid biological assessment conducted by Conservation International, the Indonesian Institute of Sciences, and Cenderawasih University. The scientific team discovered the first new bird species from New Guinea in 60 years, and a wealth of other new plants and animals. The Foya Mountains appear to be a globally outstanding repository of biodiversity.

Mamberamo River Tours
Parts of Papua Province remain an indisputable sanctuary for some of the world’s last remaining traditional human societies, specifically along the Mamberamo River. Here, in a corner of the world shielded from the passage of time and the reach of modern civilization, people continue to live in their most primal state—devoting all their daily energy to the fundamental challenges of securing food and ensuring survival.
Certain areas along the Mamberamo River remain isolated, offering a compelling destination for travelers with a keen interest in prehistoric-style cultures and the lives of Papuan communities that have yet to connect with the outside world.
Through this tour program, we invite you on an expedition deep into the dense jungles of western Papua. There, along the banks of the Mamberamo River, live the Bauzi—a nomadic Papuan tribe that remains entirely isolated from the outside world. They continue to lead a Stone Age existence, hunting cassowaries and communicating through a unique whistling language. If you are curious about the lives of the Bauzi people, this tour program—detailed on our website—offers a glimpse into what it takes to reach them.
The Mamberamo river—sometimes called the “Amazon of Papua”—is famed for its rich biodiversity and remote, untouched habitats. Here’s what you can
