'Le Vivier aux Carpes' at Seraucourt-le-Grand, near St Quentin, should be open from 1st March. We have stayed here a few times and can thoroughly recommend it - just basic, but good,facilities - unless you are a fisherman of course, in which case you will think it very well equipped. It is only about one and a half hour's drive from Calais and very central for visits to many of the WW1 battle sites. English is spoken in reception and the campsite is close to the centre of a small village with supermarket etc. When we have been there, a baker's van has called each morning, but I don't know if this would happen out of season. The e-mail address is camping.du.vivier@wanadoo.fr.
