One of my favourite standard routes is this one: Wassenaar – Delft – Maassluis – Hoek van Holland – Wassenaar (75 km). Often I try small variations, like last Saturday in Maassluis. It was market day and I could not cycle my standard route. This variation worked out rather well, but I had to get off my bike and walk a few metres to the bicycle path along the Nieuwe Waterweg. It seems as if they try to hide this attractive path as much as possible.
I will make a standard track next time, avoiding busy roads all together, which is possible. Also, I will continue along the sea instead of taking the busier city route in The Hague.
Update June 2018 – I made a gps track.
I followed as much as possible quiet roads and bicycle paths. So now I can add the map and the gps track.
