See six primate species that exist in captivity nowhere else on earth
Six species held nowhere else
A working primate rescue and breeding centre inside the national park headquarters, visited in small guided groups at set times rather than wandered around. Around 160 animals, 15 species and subspecies, and a Turtle Conservation Centre holding roughly 20 species a short walk away.
Why it's unique
The Endangered Primate Rescue Centre has run inside Cuc Phuong since 1993 with Frankfurt Zoological Society, and holds around 160 animals of 15 species and subspecies. Six of those exist in captivity nowhere else on earth, including Delacour's, Cat Ba, Hatinh, black and Lao langurs and the grey-shanked douc, and it is the only facility in the world doing captive rescue for all three douc langur species.
That is a claim about husbandry rather than marketing, and it changes what the visit is. You are not looking at a collection assembled for display; you are looking at animals that would have no captive population at all without this one site. The difference between monkeys in cages and the only place on the planet keeping this animal alive is entirely down to whether you listen to the guide.
Before you go
This is not a zoo and it is not open all day. Visits run to set times and are guided, and the times are not reliably published, so check at the visitor centre on arrival. Go in the morning slot, when the animals are active and being fed.
Ask about the doucs. Almost nobody arrives knowing what they are, and they are the reason the centre matters. Pair the visit with the Turtle Conservation Centre a short walk away. Photography rules are enforced. Donations and a volunteer programme both exist, and the centre is candid that it needs them.
