Top 4 in top 14 most dangerous pass roads in Vietnam but worth conquering.
Ma Phuc pass is located about 20 km east of Cao Bang city. This is the most beautiful pass on National Highway 3 from Phu Lo to Ta Lung border gate. The reason for the name of the pass is such that on both sides of the highway there are two limestone blocks, the walls standing together like two horses lying prostrate. The winding winding road of the limestone mountain is like a heavenly treasure of Cao Bang land The scenery on both sides of the pass is very beautiful, here you will see the triangular flower fields in spring and the green corn fields when summer comes.
