O Quy Ho Pass is located on National Highway 4D, cutting across the majestic Hoang Lien Son mountain range, serving as the natural boundary between the two provinces of Lao Cai and Lai Chau.

• Specific location: The majority (about 2/3) belongs to Tam Duong District, Lai Chau Province; 1/3 belongs to Sa Pa Town, Lao Cai Province. The pass peak is about 12-15 km northwest of central Sa Pa and about 50-60 km from Lai Chau City.
• Altitude: Around 2,000 – 2,035 m above sea level (pass peak).
• Length: Nearly 50 km, making it one of the longest mountain passes in the Northwest.

From the peak of the pass, you can admire panoramic views of the Hoang Lien Son range, deep valleys, terraced rice fields, and endless skies. This is also why the pass is often called "Sa Pa Heaven Gate" or "O Quy Ho Heaven Gate".

O Quy Ho Pass is famous not only for its majestic beauty but also for poetic legendary stories of the Northwest mountains. The name “O Quy Ho” is believed to originate from O Quy Ho village located at the foot of the pass in the Sa Pa area (Lao Cai), named by the H'Mong ethnic people. Besides this familiar name, the pass is also known as Hoang Lien Son Pass because it crosses the mountain range of the same name, or Cloud Pass as it is blanketed in floating white clouds all year round.

According to folk legend passed down through generations, O Quy Ho was the name of a young man – the son of the Mountain God – living a peaceful life in the vast forest. He was famous for his flute-playing talent, with melodies echoing through the mountains that enchanted all creatures. One day, seven fairies – daughters of the Jade Emperor – descended to the realm of mortals to play and bathe in the stream. The youngest fairy happened to hear his poignant flute music and fell in love with him.

Their love blossomed amidst the pristine forest, beside white cascading waterfalls and vast green woods. However, their bond was forbidden by the heavens. Separated by strict celestial laws, the youngest fairy transformed into a yellow-feathered bird, flying across the mountains day and night crying mournfully "O Quy Ho... O Quy Ho..." like a hopeless call for her lover. The bird's call echoed through the mountains over generations, gradually becoming the name of this legendary pass today.

O Quy Ho was once one of the most treacherous mountain routes in the Northwest. Winding passes, abyssal ravines, frequent thick fog, and stories of wild beasts, accidents, or challenging journeys defined its past.
