1. Overview of Cat Ba National Park
Cat Ba National Park covers an area of approximately 263 square kilometers, including about 173 km² of land and 90 km² of marine area surrounding Cat Ba Island in Hai Phong. Established in 1986, the park protects a diverse range of landscapes, from rugged limestone karsts and dense tropical forests to mangroves and coastal ecosystems.
Ecologically, Cat Ba National Park is recognized for its rich biodiversity and is home to many rare and endangered species. The park’s forests shelter species like the critically endangered Cat Ba langur (white-headed langur), numerous bird species, reptiles, and unique plant life. Due to its ecological importance, the park is part of the Cat Ba Archipelago Biosphere Reserve, which is recognized by UNESCO for its outstanding natural heritage.
The best time to visit Cat Ba National Park is during the spring (March to May) and autumn (September to November) seasons when the weather is mild and rainfall is low - conditions also similar to the best time to visit Ninh Binh Vietnam, another nature-rich destination in northern Vietnam. During these periods, visitors can comfortably enjoy trekking and exploring the park’s natural beauty. Visiting early in the morning or late afternoon is also recommended to avoid the midday heat and to experience the park’s tranquil atmosphere.
