Paul and Sheila Barker are the designers, writers, cartographers and photographers for the best travel website we know: www.langdale-associates.com. They have sent us the following list of websites used on recent travels in mainland Europe.

This is Paul and Sheila's list, along with their own comments:

http://www.camping-in-greece.gr/default.asp  Covering mainland Greece and the islands.

http://www.camping-frankrijk.nl/  A Dutch site which gives a thorough coverage of all the departments of France; we used this as an invaluable source of info about Corsican sites and found many small sites which got no mention anywhere else; they were consequently much cheaper than the outrageous prices charged by the bigger plebby sites.

http://www.motorhomefacts.com/modules.php?name=Campsites&op=search  I really don't like and never have anything to do with Internet Forums, since I generally find myself at odds with the values and culture of so many Forum-addicts, who have little else to fill their sad time but write whingeing notes; however, the Motorhome Facts campsites pages do have some value, if you accept that they are included by members' recommendation and you may not agree with what is said.

http://www.camping.hr/   The Croatian Camping Union offers both an excellent web-listing and a very helpful service on information about campsites in Croatia; they readily respond to emailed enquiries.

http://www.czech-camping.com/    This was an invaluable guide to Czech and Slovak campsites which revealed to us many smaller sites, whereas the ACSI website manages to include all the ultra-luxury, plebby and ultra-expensive sites; also of course sites full of noisy Dutch caravanners and our antipathy to this breed is well-known!

Martin Jeffes, entrepreneurial designer, owner and manager of Camping Sakar Hills in South-East Bulgaria (http://www.sakar-hills.com/index.html) has given us details of a Dutch website (with a version in English) which gives, free of charge, Points of Interest (POIs) to download to your SatNav. There are latitudes and longitudes for 21,351 campsites throughout Europe, which does, of course, include the UK. This is an essential adjunct to the Caravan Club's idiosyncratic directions for the sites in their 'European' guides.

http://www.archiescampings.eu/eng1/   (many thanks to Archie).

Martin regrets that he wasn't included in the list as a Point of Interest, but we have assured him that he is very much a POI. We have noted his longitude (tall), latitude (wiry), attitude (positive) and altitude (above all others in Bulgaria).

John Hughes has kindly added the following websites (the notes are ours):

"Various Dutch motorhomers whom we met during our stay in Greece recommended the following Dutch and German websites:

www.griekenlandmetdecamper.nl (means 'Greece with the motorhome'). In Dutch. Many free camping places in Greece, with maps and GPS co-ordinates)

www.campercontact.nl (means 'Motorhome contact'). In Dutch. 6 free camping places in Greece plus many sites in many other countries.

www.campervriendelijk.nl (means 'Motorhome Friendly'). In Dutch. Look under 'Camper Plaatsen' ('Motorhome Places') then 'Buitenland' ('Abroad' if you are Dutch). Many free and paying camping places in Greece and elsewhere including 1 in Albania.

www.womo.de (means 'Motorhome') In German. Devoted to selling books of free camping places throughout Europe."
