During a survey of Non Nuoc Cao Bang geopark’s values and conservation work in July 2017, UNESCO experts praised this as a fairyland. They asked local authorities to build a tourist route to explore this land, especially in winter when Cao Bang is extremely impressive with colorful forests.

These trees are called sau trees (Chinese sweet gum), and at the same time are called ‘sau sau’ trees by many people in other places. Sau trees are grown close together on the hillside of the Cao Bang region. Each tree is up to 10m tall with the main highlight being unique leaves which look like maple leaves and can change their color in different seasons.
