In reply to J1234:
I spent two weeks in Gorinchem with work last year, and took my bike with me. Did loads of miles whilst there and can honestly say it was all stunning. Especially in the general area between Leerdam, Groot-Ammers, Gouda, Kinderdijk and the Biesbosch. It would probably be worth staying in Dordrecht or Gouda or somewhere, as Gorinchem, whilst nice, is pretty small, but the trip is one I remember very fondly indeed.
