The Oostvaardersdijk is huge dike that protect the polder of Flevoland from being flooded. It’s near the city of Almere that was founded in 1975 on the just recovered land of the Flevopolder. It is a great place to see the skyline of Amsterdam and look out over the Markermeer, the former Zuiderzee. When you turn around you can look down in the polder on an impressive group of modern windmills, in the distance you see the city of Almere. This is Holland at it’s core: endless flats with the endless skies you know from Seventeenth century painting. You can drive the Oostvaardersdijk north to Lelystad and cross the lake to Enkhuizen and back to Amsterdam. On the way you drive past Oostvaardersplassen nature reserve, a large area of marshes and wild land in the Flevopolder, where they introduced wild horses and prehistoric cattle.
