The mountain’s pass is also called Cu Mong. It is part of the Nam Truong Son range, more commonly called the Nam Son range.

The pass is 7 km long, 245 m high, and has a 9% slope. The dangerous, winding pass with high mountains on both sides is hard for many people to get through because it is so dangerous.

The pass is a road that goes through one of the Nam Truong Son mountain range’s branches that leads to the sea. 

When there was no road between Quy Nhon and Song Cau, the pass was the only way to get from Binh Dinh to Phu Yen (National Route 1D).
