If you do not get a book before you arrive in Le Puy, look for shops called Librarie, or even the Tabacs/Journaux. You can pick up little books in French called TopoGuides (cost 3.90€). The one I have only covers the part from Figeac to Le Romieu (near Condom) so it looks like you will need three to cover the whole Via Podiensis. It is just possible that other books may be stocked in English, because this is the starting point for the walk. At the worst, you will at least be able to follow the maps. If you can manage it get a small dictionary, or before you go write a list from the internet of all the words you think you may need, and phrases. eg. droite - right, gauche - left, fourchette - fork, sentier - path, prendre a droite - take the route to the right, chemin - farm track or tarmac small road, sort or sortir - leave/exit, bout de falaise - cliff, parcourir/emprunter/suivre/franchir/remonter/poursuivre/passer are all words that mean follow, cross, take etc. If you get internet access while en route go to
http://www.gr-infos.com - click on the british flag. Click on the GR65 plus the first section and this will show you the map in detail, and give you all the places you can stop for the night, phone numbers, etc. Carry on clicking down the list. It is very comprehensive. When you are in the bigger towns check out the tourist offices for further information and help to book you accommodation. Mairie's in the villages will help you but a lot are only open on certain days of the week in the countryside because the people who work in them also work as farmers, etc. But if you are really stuck and you can manage to ask someone for Monsieur le Maire, you maybe lucky and get taken to see him or someone from the Mairie, to arrange somewhere to stay. I am sure that all the places on the route are used to lost/homeless pilgrims searching shelter for the night. Good luck. I live in Aquitaine, not far from the GR65. If you need somewhere for an overnight when you are near either Lauzerte on the GR65 or Pujols on the variant GR652 send me a message. I wont be here for three weeks in May (11th to 31st) but before or after - happy to help. Ange
