Bac Sum slope, the most craggy slope in Ha Giang connects Minh Tan commune – Vi Xuyen district with Quyet Tien commune, Quan Ba ​​district. Bac Sum slope – Ha Giang is considered by many people as Pha Din pass – one of the four great peaks of Vietnam. From a distance, Bac Sum slope bears the image of a giant snake with zigzag twists. Along with that is the danger by a lot of sleeve bends. To conquer this Bac Sum slope, you will have to climb each high slope and then downhill, leaning down to follow their bends. In particular, the highlight of Bac Sum slope is Chin Khoanh slope. This is a section of Bac Sum slope with M-shaped sections, which is the place where horses falter and people hurt their feet. “Bac Sum slope, Can Ty lobster, Dong Van hazel” is a saying referring to the winding and dangerous level of Bac Sum slope. Along with the ruggedness, Bac Sum also brings a soft beauty like a soft silk strip across the top of the mountain, hidden in the mist, among the craggy cat ears. In particular, in the journey to cross the slope of Bac Sum, you will have the opportunity to admire the Twin Mountain, a beautiful product of nature. The Twin Mountain appears like the round breasts of a young woman in her youth, full of life. The mountain is even more beautiful when it is adorned with terraced fields. Crossing Bac Sum slope to reach a unique place is Quan Ba ​​heaven gate. This is the gateway to Dong Van Stone Plateau. Standing on the gate of heaven, one feels like a cloud hovering over one’s head, touching one’s hand can see the cloud.
