Local businesses and stallholders have stocked up, eager to serve the seasonal influx of Thai tourists at a time when the country remains practically shut to foreign visitors.
Visitors who climb through the fields of yellow flowers to the peak of Doi Hua Mae Kham can also look down on the sea of mist that swirls around the mountain every winter season.
However, tree marigolds only bloom for a short period, so flower-lovers are advised to visit these slopes before the end of November if they want to catch the spectacular display.
