1. Rotterdam: Harbour Boat Tour
Embark on a round-trip city cruise of Rotterdam to see one of the world's most innovative ports in the world. See the busy traffic of sea-going and inland ships, listen to informative commentary via an audio guide, and admire the city's impressive skyline as its imposing buildings glide by. Start your boat tour from Willemsplein. Get a unique perspective of the harbor's shipyards, docks, and the hypermodern transshipping of thousands of containers. On the way back, soak in views of the steamship 'Rotterdam', the former cruise flagship of shipping company Holland America Line.
