Cat Ba is the largest of the 366 islands spanning 260km2 that comprise the Cat BaArchipelago, which
makes up the southeastern edge of Ha Long Bay in Northern Vietnam.
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. The island has a wide
variety of natural ecosystems, both marine and terrestrial, leading to incredibly high rates of
biodiversity. Types of natural habitats found on Cat Ba Archipelago include limestone karsts, tropical
limestone forests, coral reefs, mangrove and sea grass beds, lagoons, beaches, caves, and willow
For all of its natural beauty, Cat Ba Island faces numerous environmental problems. Increases in
tourism and recent developments threaten the ecological integrity and biodiversity of the island,
reducing and fragmenting the natural habitat for Cat Ba's numerous species. Illegal hunting and
poaching, overfishing, and water pollution in Ha Long Bay continue to threaten the ecological healthof the island.
The island is a national park of Vietnam and was recognized by UNESCO in December 2004 as a Biosphere reserve of the world.
