One of the most well-known if not the best known flea market in Tallinn is located in Telliskivi Loomelinnak. The flea market is open every Saturday from 10 am to 3 pm and you can purchase all kinds of things ranging from books and clothes to old toys and vinyl records. Kalamaja is currently one of the trendiest districts in Tallinn and there’s a lot to see and do. So, if you get tired of walking around the market then you can, for example, stop by restaurants like F-Hoone and Kukeke or have a drink in Pudel Baar. During the summer season Telliskivi flea market is an especially awesome place to visit, as in addition to treasure hunting, you can experience the local atmosphere and enjoy the weather (of course only if it happens to be sunny 😛 ). Tallinn Old Town is always great place to visit, but Telliskivi street and Kalamaja district can offer you more a genuine and bit less touristy experience. More information about the flea market can be seen on the following website (available only in Estonian).
