Khau Pha Pass is a high mountain pass at an elevation of 1,500 metres (4,900 ft) above the sea level, located in Mù Căng Chải District, Yên Bái Province, Vietnam. It’s one of the longest mountain passes of the country.
The road to the summit is asphalted. It’s called National Highway 32. With just a low concrete barrier between you and the steep mountain drop, it's best not to look down. It’s said to be one of the most dangerous roads in the country, making many people and especially foreigners eager to explore it.
The road is 30km long, pretty steep. It’s dangerous due the thick fog, snow in winters, sharp bends, no barrier or warning signs, lack of regular maintenance, risk of landslides.
