If you could build a playground for you and your buddies, what would you include? A bunch of construction equipment to screw around with? Go-Karts? How about an ATV obstacle course? Well, Männerspielplatz Erlebnis Park offers all of that and more. Located on a former factory site not far from other guy-friendly attractions like the Mercedes-Benz and Porsche museums, this "Playground Adventure Park" lets you and your friends spend all day doing manly stuff like shooting bow and arrows, digging with excavators, driving Jeeps or Unimogs off-road, and even moving stuff using cranes. To cap off your day of testosterone, book a night at the nearby auto-themed V8 Hotel.
