Berlin is a veritable treasure trove of bric-a-brac, antiques, retro items, military paraphernalia, vintage clothes & wares, crafts and random oddities thanks to the vast array of flea markets dotted all around the city. Many of these markets are public events in their own right as much as they are hives of commercial activity with street food, live music and entertainment. There's a lively buzz of activity as Berliners spend an afternoon, no doubt following a delightful brunch, sipping beers and perusing the wonderland of the eccentric, weird and rare items and other pre-loved articles that make up the colorful stalls. Arguably the most popular of Berlin flea markets is Mauerpark, it's pretty busy and pretty huge but has a real village feel, almost like a little festival, and has what's known as Bear-Pit Karaoke in the park where you can listen to (and even try your hand at, if you're brave enough) karaoke in an amphitheatre. Five minutes walk from Mauerpark is a local flea market at Arkonaplatz which is less populated and more laid-back and an ideal alternative to the relatively somewhat hectic pace of Mauerpark. The creative district of Neukölln, Boxi, Boxhagener Platz and Museum Island also host notable flea markets and there's even a night flea market one Wednesday night each month at SO36 bar & club where you can dance between browsing. Sunday is the main day for flea markets but many are also operating on Saturdays and some are open daily. We recommend asking your guide on the Free Tour of Berlin for recommendations on the best flea markets to hit up for that unique souvenir or gift and, of course, some local haggling tips.
