Chatuchak is accessible by train; it's at the last stop, Mo Chit. It opens only during weeknds from 7am-6pm. Be prepared when you get here and wear light clothing because the heat can become unbearable in the enclosed area of close to 9000 shops. Yes you heard me, 9000! Everything and anything you want you can get here. Food, clothes, plants and even animals can easily be purchased from Chatuchak. Most of the shops are wholesalers, so bargaining can be a bit difficult unless you purchase in bulk. Throughout Bangkok,this is the best- priced place; everything is cheap.
The market is segragated into clothing areas, household items, candles and incense, food, animals, plants, and lots more for easier shopping. Lots of beautiful things can be found which would make great gifts when you get home. However, be sure not to get lost because it's so big a place that it's hard to go back to where you came from. If you like something, it's best to purchase it on the spot because chances are you won't be able to find your way around if you want to return. And if you're doing lots of shopping, bring big bags, or better still, luggage, to avoid lugging numerous plastics bags around which can become quite a handful after a while. And if you're setting up a business,most of the shops have name cards that will be of help in the near future. Most importantly,drink lots of water to avoid dehydration.
