Hi Heather,
I have been told and have read many times how nice a camino the Sanabres is but by the time I had got past Zamora I just wanted an easy end to my camino and while there are still a few toughish days left, especially Benevente-La Baneza, the route north is easy. then of course there is the French way (which often attracts negative comments, from Sarria in particular) which i just love, I like the atmosphere, I especially like seeing those pilgrims that start in Sarria enjoying the camino the way I have for the last month or so. If it gets a little crowded so what!!
Regards
George.
PS If you have only got a day in Edinburgh theres still enough time to see the castle in the morning, get the bus to Leith (not far) to see Britannia after lunch
