Yet again I turn to the wealth of knowledge of FT members for advice...

Going to Dusseldorf in late August for a short 3 days. Want to spend 2 days in Dusseldorf and a daytrip to Koln. Ideally we'd be able to take a little river cruise between the 2 cities. Is there anything like that? Maybe, ferry the one way and then take the rail the other?

Thanks for the tips!

Sorry, this should be in the Germany forum, could you please move?
Thanks!
