The Four Great Mountain Passes of Vietnam

Vietnam's terrain is largely mountainous, covering three-quarters of its territory, resulting in a transportation system with many treacherous roads. Numerous winding mountain passes, with sheer cliffs on one side and deep ravines on the other, have long been immortalized in poetry as masterpieces of nature.

The slope is winding, steep, and steep.

Known as the Four Great Mountain Passes: Ma Pi Leng in Ha Giang, O Quy Ho in Lao Cai - Lai Chau, Khau Pha in Yen Bai, and Pha Din in Son La - Dien Bien, these passes are not only famous but also symbols of grandeur, challenging the courage of those who love exploration . A common characteristic of these passes is their concentration in provinces with high mountainous regions, a prerequisite for creating winding roads around mountain slopes with considerable scale and steepness.
