Mamberamo River Tours

The Mamberamo is the second-longest river on the island of New Guinea, after Sepik River (1,126 km) and the second largest in Oceania by discharge volume after Fly. It is located in the Indonesian province of Papua.

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.

The Mamberamo river—sometimes called the “Amazon of Papua”—is famed for its rich biodiversity and remote, untouched habitats. Here’s what you can expect:
