Mauerpark
Mauerpark is the last place on this list, and it surely is one of the most worth-visiting places in Berlin. The Fleamarket at Mauerpark is among the city's largest secondhand outdoor markets. The market is the perfect place for you to find secondhand treasures from different decades, even those that were once used during the World War. In this market, you'll find collectibles, toys, old books, vintage vinyl, vintage fashions, antiques, and other hidden treasures among the hundreds of stalls. The vintage goods here aren't all from Germany either. Many of the goods come from different cultures from all over the world.
Mauerpark is also well known for having multiple parties, a food market with treats from all over the world, and especially the Bearpit Karaoke event - the largest outdoor karaoke in the world, etc every Sunday. This karaoke event is held every Sunday afternoon in the park’s amphitheater. Therefore, Sunday is the perfect time if you want to get a full experience of this special market.
Being one of the most visited places in berlin, Mauerpark has become somewhat touristy and overpriced according to locals. However, nobody can take away the fact that it is still a staple of Berlin’s culture.
