Ô Quy Hồ Pass is the largest and most beautiful pass in Sapa, and also the longest pass in the Northwest region of Vietnam. The pass is known by several names, such as Ô Quý Hồ Pass, Hoàng Liên Sơn Pass, or the Cloud Pass. It is located right next to National Highway 4D, which runs through the Hoàng Liên Sơn mountain range, marking the boundary between Lào Cai and Lai Châu provinces.

Located at an altitude of 2,035 meters above sea level, Ô Quy Hồ Pass is known by locals as the “Heaven’s Gate” because the summit is often shrouded in clouds year-round, creating a beautiful and captivating landscape that attracts countless visitors.

Located at an altitude of more 2000 meters above sea level, with winding and treacherous curves, and a length of 50 kilometers, Ô Quy Hồ Pass is constantly covered by clouds at its summit, creating a breathtaking and majestic landscape. This pass makes other famous passes like Mã Pí Lèng (20 km), Pha Đin (32 km), or Khau Phạ (40 km) seem small in comparison.

Ô Quy Hồ Pass is one of the most dangerous passes in Northwest Vietnam due to its sharp curves and steep, precarious sections that seem to challenge adventure seekers. Traveling along this unique terrain, with a towering mountain on one side and a deep abyss on the other, requires careful attention. It is advisable to travel cautiously, preferably in a group or with a local guide to ensure safety.

With a route of approximately 15 kilometers, visitors can choose either a motorbike or a car to quickly reach Ô Quy Hồ Pass from the center of Sa Pa town in about 30 to 35 minutes. Starting from the central square, head northwest along the Thac Bac – Dien Bien Phu road (National Highway 4D) and drive straight to the top of the pass. Different types of transportation are suitable for different groups and experiences.

Due to the elevation difference, the climate on Ô Quy Hồ Pass between the two regions of Tam Đường (Lai Châu) and Sa Pa (Lào Cai) varies. Each season brings unique experiences for visitors. Specifically:

Summer and Autumn (from June to November): While the pass on the Sa Pa side remains fresh and cool, the pass on the Tam Đường side faces the scorching sun and the dry, hot winds from Laos, which scorch the land and green meadows. However, this is also the ideal time for adventurers to showcase their motorbike skills on the treacherous pass.

Winter and Spring (from December to May): During this period, the weather on Ô Quy Hồ Pass is more pleasant with cool breezes. When temperatures at the summit drop below freezing in the cold months of January and February, snow and ice often cover the entire landscape. Especially if you visit the pass in the early morning, you can witness a sea of clouds floating gently, resembling smooth, fluffy layers of cream.

If you plan to visit the destination for a day trip, you don’t need to prepare too much luggage. You should bring identification documents, cash, a jacket, a map, a small first aid kit, comfortable shoes, and some water along with light snacks for when you’re hungry.
