Doi Bu — known to many pilots as Hill 833 — is the oldest flying site in northern Vietnam, in operation for around fifteen years, and one of two closest site to Hanoi that Mebayluon runs. This page gathers the practical details: location, altitude, terrain, the best season, how to get there and what it costs.
📍 Where is Doi Bu?
Doi Bu lies in Nui Be hamlet, Xuan Mai commune, Hanoi. Following the recent administrative reorganisation, this address replaces the older Nam Phuong Tien commune, Chuong My district. It is about 45 km from central Hanoi, roughly an hour by car — the closest of all the sites Mebayluon operates, and easily done as a day trip.
📏 Altitude and terrain
The mountian rises 833 m above sea level, which is why pilots know it as "Hill 833". The launch point sits at 650 m, above a gentle slope running about 1.5 km.
The open terrain and steady wind are why Doi Bu is used as a training site by paragliding clubs across northern Vietnam, not just for tandem guests. In good wind seasons, pilots here have reached altitudes above 1,500 m.
🍂 When is the best season?
Doi Bu is at its best — and safest — during the northeast wind season, from late autumn into early winter, usually October to December. When the monsoon arrives the air turns cool, dry and clear, and the wind blows steadily and evenly. These are ideal flying conditions: flights lasting tens of minutes are routine. In this wind, Doi Bu is considered one of the safest flying sites in northern Vietnam, because the airflow stays steady rather than shifting unpredictably. From late October the white reed season begins — the image most associated with Doi Bu. The slopes turn white and the scenery becomes genuinely photogenic. Many groups climb to the summit just for photos among the reeds, to camp and barbecue, or to bring the whole family out for a day outdoors.
