Short answer
October and November are the best months for buckwheat flowers. The timing shifts by year and altitude, making these the busiest months on the Loop.
When it happens
The buckwheat flower (tam giac mach in Vietnamese) season generally runs from October into December, and is at its best in October and November. Because these are mountain crops, the exact blooming time shifts by one to three weeks from year to year depending on the weather and the altitude of the fields.
October and November are also the busiest months on the Ha Giang Loop. The weather is dry and clear, bringing large crowds.
Where to see it
The most famous fields are found in the northern highlands, especially around Dong Van and Meo Vac. You will see fields of small pink and white flowers planted in the valleys and along the mountain passes, including near the Ma Pi Leng Pass.
Practical & safety notes
While the weather is mostly dry, clear, and cool, this is peak season. Accommodation in Dong Van and Meo Vac books up quickly, especially on weekends. The passes can be very busy with other riders and vehicles. Travel midweek and start your days early to avoid the heaviest crowds.
