Dappermarket
Dappermarkt offers a variety of goods, from clothes to food and other daily necessities. It's a great place to find cheap vegetables and fruit. There are also nice cafes nearby. It can be considered as one of the top markets in Amsterdam.
Amsterdam North Market
The Noordermarkt market on Saturdays is quite good, with a focus on organic agricultural products. I like buying delicious food here, and there are also some other small shops. If you want to buy more books, clothes, and so on, come and explore on Mondays.
Albert Cuyp Market
Albert Cuypmarkt is a popular market where you can find various trinkets, cheap clothes, and local fashion items.
Westermarkt
If you like fashionable clothing and such, then you definitely shouldn't miss Westerstraat Market! You might be able to find some nice clothes there, and maybe even some good brands!
Stamp market
Postzegelmarkt is recommended for niche collectors, mainly those interested in stamp, coin, and badge collections. It is a small market. However, there are also many collector's shops in the surrounding area, which are worth visiting.
