VietnamPlus and Báo Văn Hoa still record 6 November. Readers should check the latest official notice from Tuyên Quang Province before planning.
When is the Tam Giac Mach blooming season?
Tam Giac Mach flowers bloom from October to December each year on the Đồng Văn Karst Plateau. This is late autumn and early winter, when cold winds arrive and the flowers reach their peak. The delicate blossoms stand out against the stone plateau and have become a tourist landmark.
To serve the festival, local areas have sown about 400 hectares of Tam Giac Mach in three waves so the flowers open in succession through the season. Flower fields are arranged across a wide area, shaping the landscape and providing photo spots. Notable sites include the Pao House, Lũng Cẩm village, Lũng Cú Flag Tower, the Nho Quế River area and Thẩm Mã Slope.
What activities are part of the festival?
Beyond the opening night, the festival includes cultural, tourism and trade activities. These include the Vietnam-China International Trade Fair (Tuyên Quang) 2026 from 5 to 11 November at the provincial sports complex with 300 booths, and an OCOP product and local agricultural goods space in Đồng Văn Old Quarter from 3 to 7 November. There is also the second "Spirit of Stone" rock show, traditional folk games, sports tournaments and cultural performances across communes in the UNESCO Global Geopark of the Đồng Văn Karst Plateau.

How is the festival tied to highland ethnic culture?
Tam Giac Mach has long been part of the life of highland ethnic communities. Once a long-standing food crop, it has gradually become a key crop and a distinctive tourism product that helps build the local tourism brand.
The festival not only honours the flower but also introduces the cultural identity of ethnic groups living across the UNESCO Global Geopark of the Đồng Văn Karst Plateau. Activities such as the Dao ethnic cultural day, the Lô Lô ethnic cultural day, the Tay people's fish Tet festival and the Lùng Tám linen weaving festival show that the event is a space for communities to present their traditional life and culture. The scale and format of each activity can differ between localities, and available sources do not cover everything, so readers should treat these as reference points.
Why has the festival become an annual event?
In 2015, the former Hà Giang Province first held the Tam Giac Mach Flower Festival. It has since become an annual event and is regarded as a unique, creative tourism product characteristic of Vietnam's far north. After administrative reorganisation, this area belongs to Tuyên Quang Province.
According to the Tuyên Quang Provincial People's Committee, the festival helps promote tourism as an important economic sector of the province. It also aims to publicise the beauty of the UNESCO Global Geopark of the Đồng Văn Karst Plateau and to honour the cultural identity of the ethnic groups living there.
What should visitors keep in mind?
Late autumn and early winter weather in the highlands is chilly, especially at night, so warm clothing is advisable. Flower viewing spots are scattered across a wide area, so travel time between them should be planned. The opening schedule and activities may be adjusted, so visitors should follow official notices from Tuyên Quang Province and the festival organisers. This is reference information and does not replace guidance from the organisers.
