The klong Lat Mayom Floating Market is probably one of the 3 most interesting floating markets on the immediate outskirts of Bangkok. This is it little part of canal on which a few boats full of fruit and vegetables are parked that makes it a "floating market"
. I must confess that the ''floating part'' of the market is quite short but Klong Lat Mayom Floating Market is also interesting for its on land part in which you will easily find something to eat among the numerous stalls before taking place cross-legged around one of its small tables and enjoy your meal. It is also a local market where you can buy fresh vegetables, fruits, fish, shrimps ..., or clothes and souvenirs, because even if most visitors at this market that is held each weekend are Thai, it's still a tourist place ...
There are boat tours on the klongs, the small canals that pass through Bangkok, leaving from each end of the market. They last 1h30 and cost 99 THB per person. I recommend you to make one, it shows a surprising facet of Bangkok and combines a floating market visit and a tour on the famous Bangkok klongs . Moreover, on weekends, when klong Lat Mayom market is open, the tours on the channels offered from the various piers of Bangkok often include a stop here for lunch.
I also advise you to combine the visit of this market with Taling Chan Floating Market 9 km away, starting rather with Taling Chan market. There is a red songthaew with a white sign (pickup that is used as a local bus) that connects the two markets for less than 10 THB per person.
