After a busy time in the Netherlands, the road-trip quartet headed to Cologne. On Germany's Rhine River, it's the country's fourth largest city and one of its oldest. Founded by the Romans in 38 BC, Cologne has a population of 10 million.

Getting around is fast and easy thanks to Germany's autobahn network. The high-speed roads are restricted to motor vehicles capable of driving at least 60km/h. The advised speed limit is 130km/h but there is no general speed limit. The roads are superbly designed, built and maintained and drivers are well-trained and cooperative. If you're doing the wrong thing, drivers flash their headlights to let you know.

It has cultivated grassland, beautiful old trees, a bicycle track and hiking trail. Nearby Rodenkirchen is one of the prettiest villages in the area.

This annual event is celebrated in various European cities. It's all about gay pride and Cologne's parade is one of the most prominent.
