Cát Bà Island

This guide to Cát Bà Island in Ha Long Bay follows the Cat Ba langur, a golden maned primate found nowhere else on Earth, and the hunters who nearly wiped out its population of twenty five hundred through the traditional medicine trade. It traces the conservationists from Vietnam and Germany who spent years watching isolated troops and relocating females between them by boat. Look up at the pale cliffs as you walk, one of the rarest primates alive may be watching from a ledge above.
