Cat Ba Island Overview
Cat Ba is the largest island in the Bay and approximately half of its area is covered by a National Park, which is home to the highly endangered Cat Ba langur. This golden-headed langur is rarely seen, as fewer than 60 specimens are thought to survive in the wild, although it is the subject of a well-organised conservation programme; the Cat Ba Langur Conservation Program, an international NGO that has its office at the National Park Head Quarters. The Park covers both land and marine areas and has a high biodiversity, although it is at risk from too rapid an increase in tourism. Other mammals in the Park include civet cats and oriental giant squirrels.
