Mã Pí Lèng Pass is a scenic mountain pass located in Hà Giang province, North Vietnam. Stretching about 20 kilometers along Highway 4C, it connects the towns of Đồng Văn and Mèo Vạc at an altitude of 1,500 meters. The road was initially built by minority groups like the Yao, H'mong, Tay, and Lolo people. The pass gets its name from the nearby Mả Pí Lèng Peak, which resembles a "bridge of a horse's nose" in the Hmong language. It's a must-visit spot for breathtaking views and a thrilling drive through the rugged terrain!
