Part 1: Ha Giang Town – Yen Minh (100 km)
This is the only section of the Loop I didn’t do. But according to people I met the road QL4C is in good condition. On this stretch of the loop you will pass one of the most famous site in Ha Giang – the Heaven’s Gate pass. Apparently it is something you should not miss (unfortunately I did).
Shortly before Yen Minh road leads down the last descend. There are quite a few serpentine. But on that stretch you get some nice view over Yen Minh, probably the best you can get of the town and the surrounding area.
