"If you’ve heard all the standard historical highlights and want a different side of the city, I’d take Alternative Berlin Tours: a free, roughly three-hour walk where informative guides tell stories about squatting culture in the ’80s and ’90s, the legendary techno club scene, the fall of the Wall, and punk rock culture, and the tour ends at a riverside “beach bar” where you can have a beer with the guide." - Matthew Kepnes
