Is Cat Ba National Park worth visiting?

Yes — Cat Ba National Park is worth visiting. It's a 17,360-hectare UNESCO Biosphere Reserve, recognized in 2004. It protects the critically endangered Cat Ba Langur, with fewer than 80 left in the wild. Trails range from short, easy walks to a full-day jungle trek, suiting most fitness levels.
