Floating markets are definitely an impressive sight, they are fun to visit, as well as to take photos. Almost all tourists who arrive in Thailand visit a floating market, mostly for the first time in their lives.
In the canal system that surrounds Bangkok, there are a few floating markets, or by their Thai names, Thalat Nam. These markets are usually very colorful, full of life, have great energies, and delicious fruits and vegetables that are grown close by.
The most famous floating market in Thailand and maybe the world is the Damnoen Saduak. Although it is one market or many in Thailand, it is an all-time tourist favorite. Here you can walk on foot near the boats, or ride on a canoe between the boats filled with fruits and food. From the boats you can smell, taste, buy, and enjoy tastes and scenes that will never end - all while riding in a relaxing canoe. This is a real Thai experience.
The market is located about 100 kilometers south of the center of Bangkok. The way here is a nice ride through rural Thailand, very different than the urban capital.
There are about 200 canals, that were a big part of carrying the water. On these canals are a few floating markets, only some of these are for outsiders, but most are for residents of certain villages.
If you rent a boat in the market, try going to one of the side canals in the area. This way you can discover the special lifestyle of the residents who leave near the water. If before you saw the wonderful agricultural produce, here you can see the origins of what is sold in the markets, and how they are grown in such fertile soil.
Bargain, vendors here mean business. Prices here are usually higher, for the tourists. If you couldn't get the price you wanted, move on to another stall.
You can get here by minibus that leaves from Khao San. You can buy tickets at travel agencies around the city.
