Hai Phong / Cat Ba

Cat Ba National Park

The forested heart of the Cat Ba Archipelago biosphere reserve and home of the endangered Cat Ba langur. Short 1–2-hour trails lead through the Kim Giao forest to the Ngu Lam Peak lookout or into the 400 m Trung Trang Cave, while longer 4–5-hour treks cross to Viet Hai; open 7:00–17:00, and bring water as there are no shops on the trails.
