The 50-kilometer long road that runs around the Hoang Lien Son Range, between the northern provinces of Lao Cai and Lai Chau, is a must-visit for adventurers.
Standing more than 2,000 meters above sea level, its top is covered with white clouds almost all year round, hence its poetic name “the Cloudy mountain pass.”
Its official name, O Quy Ho, is said to have come from a mythical bird that used to live in the area.
Travelers with a heart for nature often explore the route as part of their trip to the nearby famous resort town of Sa Pa in Lao Cai Province.
Rent a motorbike downtown and head for the Bac (Silver) Waterfall, some 12 kilometers to the west of the town’s center.
O Quy Ho’s top is a few kilometers from the waterfall. Both destinations are on the 4D National Way.
Since two-thirds of the route is in Lai Chau’s Tam Duong District, and the rest in Sa Pa, you can feel changes in the climate as you travel along the pass.
In winter, for instance, the weather in Tam Duong is quite mild, but it is very foggy and chilly in Sa Pa.
While at the top, capturing its heaven-like scenery, don't forget to look out for food stalls run by locals.
There, you can check out famous dishes like grilled eggs and rice cooked in bamboo stems, known as com lam.
It is as close to cloud nine as you can get.
