Arguably Berlin’s most popular flea market, Mauerpark is where one person’s trash becomes another’s treasure... or just someone else’s trash. Trinkets, eats and beats galore, the park is bustling every Sunday in even the worst of weathers. If shopping up a second-hand storm isn’t on the agenda, you can try your luck in the live karaoke bear pit, where large crowds truly favour the bold. Up for a Whitney Houston number, anyone?
