Mat Than Mountain (Pierced Mountain)
Núi Mắt Thần (Núi Thủng)
A mountain with a huge round hole naturally pierced through its flank, looking like an eye gazing down over the rice fields. It is the signature landscape of the eastern route of Cao Bang.
Mat Than Mountain, formerly in Trà Lĩnh district and also known as 'Thông Mountain', is a limestone peak with a natural hole pierced through its middle. The round opening is tens of metres across. Seen from afar, it resembles a giant eye, and through the opening you can see the sky behind it. It is a landmark of the UNESCO Global Geopark. Most people photograph it from roadside viewpoints overlooking the rice fields, though you can also hike near the opening (the path is steep and a local guide is needed). Entry is free, and it can be combined with a visit to Thang Hen Lake.
