Top 8 in top 14 most dangerous pass roads in Vietnam but worth conquering.
Sa Mu Pass is located in the northwestern Quang Tri region, linking the two Phung and Viet provinces of the Sunflower District, Quang Binh Province. The pass offers an elevation of almost 1,400 m above sea level bordering the Vietnamese-Laotian border. For this, the pass is named Sa Mu because the pass is a white-washed cloud that is almost 20km long. Although in the summer, the top of the air pass is still quite cold. In this season, the blind route is more beautiful as you travel through a steep, winding slope with the mist covered around the mountain pass, which adds to the magnificent view of Truong Son range.
