Scenic route across the Netherlands, West to East
 

Three bikes travelling across the Netherlands in July on our way to Estonia. Any recommended scenic routes to get across once we have avoided Rotterdam on the motorway? We are headed to Worpswede in Germany for our first overnight stop.

I live in the Netherlands and the only road I have ever been on that comes close to being scenic would be down in Limburg (there are switchbacks!), a tiny corner of the country between Belgium and Germany that is not on your route.
