The horticulture exhibition in Udon Thani takes place from November 1, 2026 to March 14, 2027 in the Isan region of northeastern Thailand. The international exhibition is located at the Nong Dae Wetland. Visitors are welcome daily from 08:00 to 20:00. Here you can see gardens from different countries, projects by Thai organizations, greenhouses, agrotechnology and cultural performances. A standard ticket for foreign visitors and Thai citizens costs 199 baht, and online registration is required before each entry. The exhibition’s topic is the diversity of life and the connection between people, water and plants for a sustainable lifestyle. It is more than a walk among greenery: the exhibition brings together garden art and plant-growing technology. If you are planning a trip to see a specific performance, check its schedule in advance. Current as of November 2026.
What to see at the exhibition
The expo territory covers 164.8 hectares. Organizers have announced six main exhibition zones, including international gardens, greenhouses, modern agrotechnology areas, a carbon forest and a plant nursery. This mix lets visitors explore both ornamental gardening and solutions for growing and preserving plant life.
The international section features 32 gardens from 17 countries and two international organizations. Thai organizations prepared another 16 gardens, and a separate group of displays brings together more than 50 plant gardens. So the main reason to visit is not a single flower arrangement but the different approaches to designing green spaces in one place.
The expo also has international status: the horticultural association AIPH approved it as a Category B exhibition. The association’s pavilion features the interactive installation “Plant Being” by the French studio Studio Organique. Electrical signals from a living plant are converted into sound and projected colors in real time. This is one example of how the plant theme goes beyond conventional garden displays.
When and where
Exhibition dates in Udon Thani: from November 1, 2026 to March 14, 2027. Visiting hours are daily from 08:00 to 20:00, Thailand local time. The dates are confirmed by the official exhibition website. The official opening ceremony was held the day after visitor admission began.
The venue is the Nong Dae Wetland, Kut Sra subdistrict (tambon), Mueang Udon Thani district, Udon Thani province. The published site description gives the district and locality but no street, building number or postal code. For directions, use the exhibition name and the Nong Dae territory as reference points, and check the entrance location in the organizer’s current information.
The exhibition is not in Bangkok’s center and not on a resort coast, but in Udon Thani. If you plan to spend more time in Isan, you can browse other regional events in Isan event listings.
Program: gardens, performances and rotating displays
The exhibition program in Udon Thani includes 12 announced events and displays that change every week. So the set of available exhibition projects may differ from day to day. Before visiting a specific themed display, it is best to check whether it is running on your chosen date.
The cultural side is also large-scale: more than 200 performances are announced in the “Lan Tum Hom” zone during the expo. This is a separate strand of the program alongside the international gardens and agrotechnology. However, check the exact time of a specific performance against the organizer’s announcements, not against the venue’s general opening hours.
The territory also hosts an eco-market with more than 50 local vendors. Its concept centers on reducing waste and plastic use. The market complements the exhibition zones, but the event’s main theme remains the same: plants, water ecosystems and sustainable ways of interacting with nature.
How to get there and get around the territory
Bus routes are available for trips to the exhibition. Blue route connects the first Udon Thani bus terminal and the railway station with the event site; the stated fare is 13 baht. The brown route runs from Kumphawapi Market through the first bus terminal to the exhibition, with a maximum fare of 52 baht.

A temporary railway stop has also been set up for visitors near the exhibition. Reports on transport infrastructure mentioned stops for express and local trains. Before setting off, check the current timetable and whether boarding or alighting is possible at this stop: details of specific services are not given in the event materials.
Inside the territory, there are free electric trams. They run at intervals of about 10 minutes on four main routes. With an expo area of 164.8 hectares, internal transport is especially useful for moving between distant zones; it is best to confirm stop locations on site.
