What a lovely reply! Whoever is lucky to walk with you, dear
@Ignacio, is in for a wonderful journey.
Just another thought about timing, I walked the Primitivo x Norte in July last year and it was busy but fine. I had booked in O Pedrouzo and Santiago in advance and was glad I had. I did call ahead for beds sometimes too, but only 1 day ahead. So June on the coast and July inland would work well as well. Be careful about getting to Santiago around St James's day 25 July, it's very busy and you should probably have a reservation.
Flights from that nice little airport Asturias are not year round to London, so check that out. But could be so handy for a connection from LHR to LAX. Here is
the bus timetable for the airport which makes great connections with three places on the caminos. Its about 40 minutes to Oviedo.
Ultreia!
