The Khlong Lat Mayom Floating Market is a small market that is located about 15-20 kilometers from Khaosan Road. We opted to go there to get away from the more touristy floating markets. Well it turns on everything I read was true. There were only a handful of travelers passing and the rest of the crowd consisted on locals.
You can get on a boat that takes you around the river for only a few baht and it is a quiet place. The market had a ton of food to try as well as other crafts and goods. If you want to get away from the crowds and tourists it is a good place to spend a morning or afternoon.
