Maolan Karst Reserve
Guizhou's quietest UNESCO karst forest: sinkholes, jade pools, and headlamp caves without the Xiaoqikong crowds.
What it actually is
A UNESCO-listed karst (limestone landscape eroded by water) reserve in Libo, Guizhou, where you can hike into sinkholes, swim in jade pools, and cave through ancient reefs without the Xiaoqikong crowds.
Editor's take
Worth it if you're reasonably fit, want raw karst over polished tourist-park scenery, and can hire a guide to find the good sections - skip it if you're expecting an easy stroll, you're traveling in high water season, or you've already seen a lot of Guizhou/Guangxi karst, because plenty of people leave feeling it was ordinary and not worth the ticket.

Primal cycad sinkholes
Maolan's sinkholes are studded with cycads (ancient palm-like plants that pre-date the dinosaurs) and tree ferns — a forest type that survived from the Jurassic, set inside karst (limestone landscape eroded by water) collapse dolines.
Jade pools at Qinglong Tan
The Qinglong Tan pool sits in a sinkhole-lake chain where groundwater stays a steady jade green year-round. Visitors wade in from a wooden plank walkway; bring water shoes, the rocks are sharp.
Headlamp cave at Jinshi Dong
Jinshi Dong's three chambers are lit only by your headlamp — a guide leads you past rimstone dams and rimstone pools (calcite terraces shaped like rice paddies) that catch light like wet glass. Avoid going after heavy rain; the lower chamber floods fast.
