Bac Sum Pass
Dốc Bắc Sum
The first large switchback slope on the way north from Ha Giang City to Quan Ba, where the zigzag mountain road winds around layers of valleys.
Bac Sum Pass is on National Route 4C, about 25 kilometers from Ha Giang City toward Quan Ba. It is the first long switchback mountain road before entering the stone plateau. The road zigzags up the mountainside, and the viewpoint at the top overlooks the winding road and the terraced fields and villages below. It is the first photo stop on the loop. The road has sharp bends and steep slopes, and there is a lot of heavy traffic. When you stop to take photos, pull over and watch for oncoming vehicles. Rockfalls occasionally happen during the rainy season.
