O Quy Ho Pass, at a height of more than 2km on Hoang Lien Mountain, was covered in snow on November 21.
Hundreds of tourists and local people flocked to the National Highway 4D portion between Lao Cai's Sapa tourism site and northern Lai Chau province to enjoy the spectacular scenery.
The following photos were taken by our reporters several hours after the snowfall had brought the temperature down to 1.5oC.
