1. Pattaya Floating Market
The city of Pattaya hosts the largest floating market in the world – over 100000 square meters, and if you haven’t seen any before, you should know it is a peerless experience. Split into four parts, each representing a region of Thailand, it is probably the most complete floating market.
You can find virtually anything: there is no dish that can escape your grasp, from all the Thai regions and eras, houses representing the various architectural styles of every region, hand-made craftwork, daily feature shows, and a wood-carving museum. It is open every day from 10am to 11pm and the entrance fee is 200 baht.
2. Khlong Lat Mayom
Another market mainly for the locals, this one is very easy to reach. From the center of Bangkok, it’s about 100 baht by cab. It is very close to Taling Chan, so if you are hunting for floating markets, you can easily visit two in the same day and get an idea.
In Khlong Lat Mayom you will probably be the only tourist, but unlike Bang Nampheung, this is a 100% traditional Thai market. It’s probably the most recommended in Bangkok if you want to get the best out floating market visits: authenticity, relaxation, and lack of tourist fuss.
3. Damnoen Saduak
Probably the most popular floating market in Thailand, Damnoen Saduak is located about 100 kilometers outside Bangkok. It offers the most authentic feel of the archaic lifestyle, making it ideal for pictures, and to get the best idea of what Thailand tradition is about. If you want to avoid tourist crowds, you should go there early, preferably before 9 am.
4. Bang Nampheung
A relatively young floating market, this one is located in the Samut Prakan Province, built along a tributary of the Chao Phraya River. It is famous for the souvenirs and hand crafted items, but it is rather for Thais, in the sense that it’s not very rich in traditional cuisine, offering instead products considered exotic by the denizens of Bangkok, such as fruits and foods that aren’t native to Thailand.
This floating market is located in the Samut Songkhram area. This market used to be a favorite place for Thai tourists. While the internet made it popular for “farangs” as well, it is a good mixture between the riverside market and Tha Kha.
