On the same road as Wat Pho and the medicine market, keep going a little further and you will end up in a very surprising area. I arrived there, and I found myself in the flowers market, with a huge indoor market with only fresh flowers.
Outside also, a lot of shops are selling flowers, it’s quite amazing to see all this flowers everywhere. There are also many indoor food markets, the atmosphere there is stifling, stifling with unknown smells, heat and moments. Bangkok will drive you crazy !
