The Chongzuo Ecology Park, also known as the White-headed Langur Nature Reserve, protects a population of one of China's rarest primates across a series of karst limestone hills covered in subtropical forest. The white-headed leaf monkey — or white-headed langur — is endemic to this corner of Guangxi, with the park holding a significant share of the world population. Morning visits give the best chance of sightings: the monkeys move along the cliff faces in family groups at dawn, more visible against the rock before the heat drives them into the canopy.
The park itself is small enough to cover on foot in a morning. The observation platforms on the main ridge offer views over the karst peaks and, on clear days, glimpses of the limestone valleys that extend toward the Vietnamese border. It is not a dramatic park by Chinese standards — there are no cable cars or curated viewpoints — but the combination of rare wildlife and unvisited limestone scenery makes it genuinely worth the detour. Entry is straightforward and the park sees a fraction of the visitors that come to Guilin or Yangshuo.
