Part 2: Yen Minh – Dong Van (45km, 85km for Lung Cu)
The second part of the loop is a very interesting journey, especially if you add the detour to the Vietnamese North Pole Lung Cu, the most northern point of Vietnam.
From Yen Minh follow the main road out-of-town, until you reach a main road. After passing some rice fields you come to a T-crossing. Turn left onto the QL4C and the road will lead you back up to the mountains. When you reach the top, stop briefly and enjoy the scenery. To the right you can see Yen Minh, to the left the road that leads to Meo Vac. It really is a nice view.
