Non Nuoc Cao Bang covers around three thousand square kilometres of the far northern border country and was designated a UNESCO Global Geopark in 2018 - a different programme from World Heritage, aimed at geological heritage managed with local communities. What it protects is a mature tropical karst landscape: tower and cone hills, caves, underground rivers and collapse lakes, along with fossil beds and the marks of several geological eras. Three signposted routes loop out from Cao Bang town, taking in Nguom Ngao cave, the Thang Hen lakes, Phia Oac mountain and the Ban Gioc falls on the Chinese border.
What you actually see

Honest expectations
Distances between sites are long on mountain roads. Some areas near the border have access restrictions. Signage and interpretation are thin outside the main sites. Rain closes roads in the wet season.
Nearby
Nguom Ngao cave and Ban Gioc are north-east; the Thang Hen lakes are west.
