A white-tailed eagle in the city? An encounter with Europe's largest eagle is not unusual on a guided kayak tour through Rostock harbour. Two-person kayaks paddle from meeting point to meeting point as a guide explains the milestones in the development of this Hanseatic city, starting with the first Slavic castle. And if the white-tailed eagle is feeling shy, perhaps a kingfisher will fly in front of your camera lens instead.

Trier: on the road with the Romans

The band 'Kraftwerk' is one of the most influential pioneers of electronic music and paved the way for electro-pop and techno. And the cult Krautrock band 'NEU!' influenced David Bowie, Depeche Mode and Sonic Youth with their experimental sound. On their city tour 'Sounds of Düsseldorf' , two expert music journalists will take you to legendary clubs and music pubs – and of course there's plenty of music to listen to along the way.

Berlin: the vibrant world of street art

Graffiti, murals, stencils: the terms are as diverse as street art itself. In Berlin, the works of street artists have long been an integral part of the city's cultural scene. Whether large-scale murals or small stencil art, a tour on foot and on the underground through colourful neighbourhoods will introduce you to the artists and their individual styles as you discover secret corners of the city.

Munich: relaxing on three wheels

A different kind of dinner: each course of a three-course menu in the capital of Baden-Württemberg is linked to a different location. The city guides accompany this culinary walk with entertaining stories from Stuttgart and, of course, typical Swabian cuisine. Spaetzle or pasta – as an alternative, you can also choose a Mediterranean version.
