[Gocamino] Camino to Fisterra

[Jeff Mayor]

This summer I am beginning my Camino in Astorga and I plan to continue 
out to Fisterra. I figure that I can make Santiago in 10 to 12 days, 
which leaves me with about 10 more days to explore the coast.  Looking 
at John Brierley's map, I see that there is a Muxia extension that 
circles around back to the main route. Has anyone done this route? What 
about the detour to Bainas to the Dolmen or the Dolmen outside of 
Maronas, are these worth the trip? Another thing I was considering, if 
it is possible is to to catch a bus (train?)  North along the coast at 
Muxia and head back to Bilbao though Gijon.  Has anyone tried this?
