The question was:
Can anyone suggest which is the best route to go?
Santiago to Muxia to Fisterrra (then bus back)
Santiago to Fisterra to Muxia (then bus back)
Veer left or veer right at Hospital?
I have a feeling that Fisterra should really be the last point in the journey.
Read the conversation on walking to Muxia or Finisterre first in our Camino Forum.
