Often bound in heavy fog, Cổng Trời Ô Quy Hồ or Heavens Gate, is a lesser known temple complex and viewpoint, situated atop the Ô Quy Hồ Pass, one of Vietnam's most majestic mountain passes. Located approximately 18 km's from Sapa town, this pass connects the provinces of Lào Cai and Lai Châu. Perched at an elevation of 2035 metres, it offers visitors panoramic vistas of the Hoàng Liên Sơn mountain range, including glimpses of Fansipan, the highest peak in Indochina.
