Hi , we stay at a site called Les Hautes Coutures its 5 minutes max from the port of caen.Its easy to get to just beside the bypass, they are geared up to recieving caravans off of the late ferry [11pm]. Your not disturbed by the noisy traffic there and you can get a good shower etc before you set off. We also stay there on the way back we normally catch the 9am ferry. More relaxing than the ferry port but more expensive .Alan
