I plan to walk for 2 weeks & have been thinking to start in O Cebreiro & then walk to Finisterre, but it looks like getting to O Cebreiro from Madrid is a bit difficult--buses only leave early from the airport & I am afraid I might miss the connection. The other option is to fly into Santiago & take a bus from there, but I feel like I do not want to be in Santiago until the end. Are there buses from the airport or would I need to go into the city & get a bus from there? Any recommendations? I don't want to lose a day in transit in the airport in Madrid, so not sure what to do.
