The famous floating market, and unlike others which are standing markets floating on water, this one uses boats to buy&sell.
You go around and stop where you request. Some sellers have fixed stalls some have boats that come to you. The coconut ice cream selling boat had some delicious stuff. You can barter on prices but don't be too harsh, they are only trying to make a living
You can also float around and see the houses and the local life here. Completely different to the western world but they seemed happy. Covid has really hit this place hard and it's very quiet with very few tourists and boats.
