I have read many mixed reviews about the floating markets in Bangkok. Originally i didnt realise they were 100KM out of Bangkok - Is it actually worth seeing?
As a seasoned traveler, and traveler who likes locals-only experiences, Damnoen Saduak was a fail for me. Locals don't shop here, they only sell their rows and rows of repetitive trinkets.
For the price and time commitment, I would have rather seen/done something else in the city personally. I also have a slight issue with germs (Thailand, I know), but I swear they made my noodle soup with the river water - which you'll see isn't exactly clean.
I hear there is a floating market in Bangkok, which I'm mad at myself for not checking out instead.
If your schedule allows a day trip, you can hire a driver to take you, I haven't been to Damnoen Saduak Floating Market but I've been to Amphawa Floating Market and it is an amazing sight. It's packed like a bar, wall to wall people, you can barely walk, but I loved every minute of it.
I love venturing out of the city on holidays. It gives you a different view. Your driver might try to take you to a boat dock to take a boat in, I would check into this first, because they charge a lot for the boat when you are tourist... so get someone from the hotel to book it and confirm your drop off point, when you get in your taxi/driver. There may be a temple with stop that goes back and forth, so ask someone, instead of going way out of your way because the driver gets a kick back.
It's just a serious time factor and traffic!

If it's the first time in a floating market then an unqualified yes. Get a boat with just you and your friends instead of the communal boats. It's worth the money.
The Central Park of the market at noon is not to be forgotten.

If you haven't been to Damnoen Saduak Floating Market, I think it's worth going just once if you have the time. I wouldn't go a second time though because it is pretty far outside of Bangkok. Also seems like a tourist trap because the taxi drivers will take you to a place where you pay quite a bit to get on a water tuk tuk to see the floating market. Negotiating prices at the market is easy though so if you are not happy with paying the initial price for your item(s), bargain with the vendors until you get the price you want. It took a whole afternoon (almost 1.5 hours to get there and 1.5 back) to go to Damnoen Saduak so make sure you set time aside to do it. If your time is limited in Bangkok, I would recommend going to a closer floating market in the city. It's probably more local and authentic anyways, which is a plus.
