campsite stopover near santander in march

A site which is open at that time of year and close to the port is Camping Virgen del Mar. Few others are.. But dog owners need to be aware that this campsite does not admit dogs. 

However with ferries timed as they are these days you are not limited to an overnight near the port so you can do an internet search for sites or motorhome aires further away.

thanks for that will lock on net
