This has to be one of my favorite places in Bangkok. There are plenty of opportunities to people watch or simply enjoy the hustle & bustle of tuk tuks and buses. However, it may not be for those who aren’t used to the heat and humidity.
During the daytime there are many wholesale shops if you are looking for some bargains or souvenirs to take back home. But for me personally, I prefer going to Yaowarat Road at night when the area comes alive with its night markets.
In my opinion, I don’t think that you need to spend too much time in Chinatown. It can be done in two to three hours at night after your day of sightseeing. But if you want it to be more of a shopping experience, then go during the day when most of the shops are open.
