Getting to Chatuchak has never been easier. Here is a list of transportation that would get you to one of the world's largest flea markets.

BY BTS TRAIN:
By Bangkok's Skytrain, just exit at Mo Chit (the last stop on the Sukhumvit line) and follow the crowds. This would take approximately half hour if you're coming from the city centre.

BY BUS:
Aircon buses with the numbers 2, 3, 9, 10, 12, and 13 will take you there as well.

BY TAXI:
Too hot to go by public transport? Take a cab! Always insist on travelling by metre. It costs around 60-120Bht (depending on traffic conditions) if you're coming from the city centre.
