Hello
@Samos
Yes, I have walked a few trails from Arles via Turin to Rome -when on my way to Jerusalem in 2013. It was a grand experience. I have some wonderful memories.
From Arles I followed the
GR 653d to Montgenèvre then over the pass to Cesana-Torinese...
...From there I continued along the
Via Francigena via Turin as far as San Quirico d´Orcia. At which point I turned left and made a detour along local paths and sentiers across Tuscany and Umbria via Castiglioni del Lago,
Isola Maggiore and Perugia to Assisi...
...from Assisi I followed
Il Cammino di San Francesco via Rieti to Rome then beyond.
Afterwards i put together a couple of resources and posted them here on the forum (sign in to download). Included were stages walked, places to shelter, and notes on guide books, pdf´s and maps. Although it is a number of years since I walked to Rome, there may still be something of use to you in them.
All the best with planning,
@Samos.
Regards
-Lovingkindness
