Hello Laurie ,
I don't know about the way through Oriols as we walked to Medinya throu Vilademuls. Most of the walk is asphalt except the two or three last kms before entering Medinya where we meet again asphalt.
Yes, many up and downs some of them steep. We met "dissuasive" dogs, i mean barking a lot but no attack. Those dogs were free to go on the small road we were walking on...
I also wish to mention the fact that, when entering the village of Terradelles, you'll have to be very careful as signs are not placed where they should be.. (pse refer to our diary !).
Before you enter the village, you pass a round about. Fifty or hundred meters, you turn right and find a gentle slope and, on the left side, a sign indicating the way. Now, you are in the right direction.
We had lunch (at about 2.30pm) in "Hotel restaurante Medinya" on the main road. Cheap 7 €. From there we took a bus to Girona.
What we saw from the bus window gave us the satisfactory impression that we did'nt miss anything at all...
I can't remember having noticed any lodging possibility between Bascara and Medinya.
I do remember that, the pension owner we stayed with, close to Bascara, said that most of the peregrinos walked through Oriols.
Buen Camino, Laurie !
