Part 4: Meo Vac – Ha Giang (150 km)
From Meo Vac you have two options. You can either follow the loop to get to Yen Minh, or you could take the road south towards Bao Lac. In theory could use that road to get to Ha Giang via one of the more southern road, though you follow one of the main roads in the area. Taking the southern road you could also head to Cao Bang if you are interested incorporating the Cao Bang Loop.
