Flea Market Kanzlei
This is the largest flea market in Switzerland that operates all year. Every Saturday you can find around 400 different stalls lined up with different goods for sale, including normal people who are just wanting to sell their old stuff and traders who do this for a living.
Flea Market Bürlipatz
This is the best flea market to go to if you are looking for antiques or other odds and ends. Not only will you find some of the typical professional traders, but you will also find people about to move and selling everything.
