Thank you for prompt reply. I am torn between the Arles / Aragones route and the Piamont route. There was one very informative post that suggested the Arles route had better scenery and facilities along the way. My intention is to start one or the other at about the 1/3 mark (Carcasonne or Toulouse ) . I usually walk alone and value the company of other pilgrims over a glass at night. I’ve been on the Le Puy and met many lovely people. So hard to decide.
I walked the Arles route quite a bit ago (in 2009) and the Piemont route in three installments (in 2012, 2022 and 2024).
Looking at gronze and ign, the Arles route changed its course a bit here and there, but the accommodation is still mostly in the same places.
Accommodation wise, I think both routes are about the same, rougly one choice per day, sometimes another option somewhere in the middle of the day. Calling ahead is usual, especially if there is a dinner option.
Services wise, you need to plan ahead for both routes, for water and for food.
Scenery wise, both have spectacular parts: the Arles especially around st Guilhem-le-Desert, the Piemont around le Mas-d'Azil and st-Bertrand-des-Commingues.
Panoramas wise, the Piemont is closer to the Pyrennes so of course panoramas here are better and more frequent.
Company wise, the Arles is perhaps a little more travelled? This year on the Piemont (I walked Bezier - Carcassonne) I was told that rougly every day there were one or two pilgrims passing through.
