Khau Coc Cha Mountain Pass is an exciting adventure for travel enthusiasts. Located on National Highway 4A in Cao Bang province, the pass has a steep slope and consists of 15 floors with 14 bends. With a total length of 2.5km, this route takes a lot of time to complete due to its unprecedented height and dangerous curves. The top of the pass provides breathtaking views of the surrounding wild nature, Dong Mu valley and Pac Thoc peak, all of which can be enjoyed even more when accompanied by walking trails, terraced fields and bamboo forest. Visiting Khau Coc Cha is certainly an experience not to be missed!
