‘Het Groene Hart’ (the Green Heart) is a green area in the so called Randstand in the Western part of The Netherlands. It is more or less the area between Amsterdam, The Hague, Utrecht and Rotterdam. You would not expect quiet roads and small villages in the proximity of the big cities. But on a bicycle you can really make very nice tours here.
This tour follows mostly quiet roads, but there are also a few busier stretches.
Here are a few pictures from internet; I will soon add my own pictures.
Starting from my home in Wassenaar it is 85 kilometers. If you make this tour from Leiden, it is around 70 kilometres. As you can see from the height profile (below the map) a large part of this route is below see level. You don’t really notice this when you are on the spot.
If you want to ride this route yourself, you can download the gpx track below the map.
