Highly, highly recommend taking the brewhouse tour! I booked it on TripAdvisor and it was an…read moreexcellent activity since I was traveling alone and didn't really speak German but still wanted to try some beers. The tour guide Elise was awesome, ordered beers for us and educated us on brewhouse culture, and our group gelled immediately. We went to a variety of brewhouses and I learned so much about beer and Cologne, even though I've been on many brewery tours before. Definitely check it out.

The place where World War II started for Belgium and Germany is absolutely worth the visit. The…read moreguided tour through Belgium's biggest fortress gives you a very good idea of the kind of fortress, but the individual history of the fortress makes the visit even more interesting. It's the place where the Germans used revolutionary weapons like "gliders" and the "shaped charge" for the very first time. The visit to the part of the fortress damaged by the shaped charge is one of the highlights. It's very interesting too to walk on the hill that has the fortress inside of it. The kind of day trip that deserves far more publicity than it gets for the moment!

Took this tour soon after arriving and can think of no better introduction to the city of Cologne…read more Our tour guide Mike was from Buffalo, New York, US, and from arrival was friendly, knowledgeable, and fun. Having majored in history, he perfectly combined historical information with humor. Mike pointed out not just the architectural details in the buildings and sculptures, but told us the stories behind them to give us a true flavor for the people and background of Cologne. When the rains picked up, Mike knew where to take us for cover and always kept a positive outlook. While this was a free tour, Mike told us upfront that this is how he makes his living. Considering that his tour was as interesting and entertaining as a movie, I gave Mike a well-earned, generous tip, and so should you!
