This part next/behind the Maritime museum is hardly noticeable from the Schiedamsedijk street level. You will see the light house, a crane, ships and other heavy metal objects sticking out on the quay.
This is the outdoor and permanent part displayed and demonstrated by the Harbour museum (now part of the Maritime museum too). It will tell you about the history of the port way back in the days when it was in the center. There are some new art pieces too, look out for them.
Walk towards the water and you will find a walkway floating from the Leuvehaven towards the Wijnhaven area. This is the Kraneschipbrug.
This shortcut is not only handy if I’m on my way home or going to the Witte de With quarter. It’s a nicer ride as it’s a whole different area and you don’t really realize you’re passing some islands right in the center.
You can’t miss the red lightship at the end of the walkway, it’s Vessel 11 and a British gastropub/venue. Check out the Regentesse bridge with the lions, can you spot some lions on a rooftop too? And The Floating Staircases will be there the whole summer season, a place to hang out and stick your feet in the water if you need to cool down.
