After a great start in 2009, and over 200,000 visitors and 15,000 motorbikers in 2010, they expected around 25,000 motorbikes this year, from all over northern Europe and Scandinavia.

With it's broad streets and grand Allées, diversity of architecture, beautiful rivers, lakes, bridges, parks and gardens, and infinite layers of history and culture, Berlin is close to the top of the list of great cites for immersing yourself in culture and history, anywhere in the world.

On the way southeast out of Berlin, you should take a ride along Mühlenstraße and visit the East Side Gallery.

It features murals by artists from all over the world, painted in 1990, just after East suddenly became West, and the overpowering desire for freedom dissolved what was known as the "Anti-Fascist Protection Rampart" (In German: Antifaschistischer Schutzwall).
