2 hour tour of the Alster + canals for 19 euro! Plus on-board English audio guide! And a waitress…read moreto serve you whatever you want to drink! The boat is fairly comfortable, the driver was very nice and the German part of his tour that I could understand was funny and informative. The audio guide was good for English, French, Spanish, and a dialect of Chinese. A map was also included in the mini-computer which was fun to look at. The tour itself is really interesting and this part of Hamburg is beautiful. I found this boat tour to be more interesting than the harbor tour. Buy tickets at the booth before you get down to the boats!
