Bangkok Farmers Market is an event that you can expect to buy organic or healthy products such as organic vegetable, fruit, rice, bread, cookie, muffin, soap, massage oil, and so on.
I have been to this event by chance when I went to The Jam Factory. I found out that there were also handmade products selling in the event too.
The events will be held at different venue, and the sellers at each event will not be the same. Usually the events are held on Saturdays and Sundays in Bangkok such as at K Village (Sukhumvit Soi 26), Gateway Ekamai, Siam Square One, or other nearby cities such as Hua Hin.
The events are held almost every week. If you are interested in the event, you can check the upcoming events and updated information at their website and Facebook fanpage.
