Sunflower Festival in Thailand starts around November and goes on until about February. The best places to see sunflower fields are in Nakhon Ratchasima Province . Thousands of people from Bangkok head this way at the weekends for a day trip to take pictures in the sunflower fields. For people in Lopburi it has started to become a major tourist attraction. Each farm takes turns in planting the sunflowers so that there is at least one area of blooming flowers during this period.
