Joe!
I am at the auberge you mention ( in Tapia) arrived late as we started from the auberge in Luarca that is really not in Luarca ( 2kms before). I was going to mention that turn in Porcia it is very confusing. My walking buddy asked someone and they kept pointing to the correct place BUT I was incident on turning as it appeared closer to the water.
The answer is to keep going straight up that hill if heading to Tapia! We took a wrong turn, thankfully, we ended up on the red and white route that David mentions in his book. He wrote it in the margin and like my children I don't read the ( important) stuff written in margins
.... This little detour was AWESOME!!!!
I'm walking with a really fast guy who is a Caminoist and eager to pick up the pace some. I have not felt I had to go to the cathedral, Finnesterre or Muxia until today.... Really hoping to squish Finesterre in ( though Muxia is my love).
