I have already put on various blogs some of pics I took last summer of the voie verte de Caen à Ouistreham. I've now dug out some more of the Ouistreham end. These were taken coming from Caen (top to bottom): interpretation board "The Ports of Ouistreham"; interpretation Board "Caen to Ouistreham Greenway"; police patrolling the greenway; cyclists leaving Ouistreham; coming into Ouistreham; ditto, with cyclists; boarding the Portsmouth ferry now; close-up of ferry; the greenway continues westwards along the coast.
How well-known is Westerham in Kent? It's not far from Croydon where I grew up. The placename is Anglo-Saxon and means 'western farm or homestead'. Interestingly, Ouistreham is cognate (comes from the same Germanic roots) and means exactly the same thing. It was a Saxon settlement, older than the Vikings who settled in Normandy in the 9th century and gave the duchy its name; the inhabitants of this farm were among those who didn't make it to Britain with Hengist and Horsa (no ferry in them days).
