Cat Ba National Park is the ecological heart of Cat Ba Island, a UNESCO-recognized Biosphere Reserve known for its incredible biodiversity, dramatic limestone karst landscape, and a unique combination of terrestrial and marine ecosystems. It offers nature lovers and adventure seekers a chance to explore Vietnam’s wild side.
General Overview and Ecosystem
Location: Situated in the center of Cat Ba Island, approximately 15 km from Cat Ba Town. It covers nearly half of the island’s land area, extending into a significant portion of the surrounding sea.
UNESCO Status: The entire Cat Ba Archipelago has been a UNESCO Man and the Biosphere Reserve since 2004, and is now part of the Ha Long Bay – Cat Ba Archipelago World Heritage Site (inscribed 2023).
Ecosystem: The park is unique as the first protected area in Vietnam to include both land (11,000 hectares) and marine (6,500 hectares) components, encompassing tropical rainforests, mangroves, limestone karsts, and coral reefs.
Flagship Species: The park is the last natural habitat for the critically endangered Cat Ba Langur (Trachypithecus poliocephalus), one of the rarest primates in the world, with only a small number of individuals surviving here.

Activities and Main Attractions
The park offers several well-marked trails and unique sites for exploration:.
