Damnoen saduak Floating Market in Ratchaburi is one of the most popular floating markets in Thailand. Every day many Thai and foreign tourists travel here to shop, eat, and absorb the atmosphere of Thailand water markets that have been like this for over 100 years. Klong Damnoen Saduak Damnoen Saduak is the straightest and longest canal in Thailand. The canal was built on the royal initiative as King Rama IV of Thailand wanted to link the Mae Klong River with Chinese river ways to support transportation and trade. It took over 2 years to dig and was eventually finished under the reign of his successor King Rama V. The canal is 32 kilometers long and has more than 200 branches. Damnoen Saduak Floating Market's popularity grew to new heights in 1971-1973 when the river was full of farmers on their boats selling their wares. And that is the way trade is performed in this area until today.
