Hi Kat 123,
I concur with my comrade from BC Canada,
Start in Santiago , fly there direct. .
Walk 3 days to Fisterre , stay an extra day ,
Walk to Muxia , stay an extra day =======6 days gone
Return to Santiago on early bus and have two there before flying home =======8 days now gone.
1/ You will have two compostela's in your "back kick" if these are important [ they are not with us] , experienced at the end two lovely villages which are important in relation to the camino, especially Muxia and enjoyed nice towns on the way there.
2/ It will give you an insight into the
Camino Frances which you can achieve when you have 5 or more weeks available.
I would be disappointed in the 8 days if i finished in Santiago.......
From our experiences;
You will see people of all ages,nationalities,shapes and sizes all in the square who have walked varying distances , some 1600km plus.
You will want to be part of this whole experience because it's lovely with raw emotion shown in many, many cases.
I would and i think you might Kat think ....i wish i did it all.....
Come back after you short warm up mate and enjoy this wonderful experience.
Buen Camino,
David
