How many days should I plan........

Hi, M,

You'll find lots of information on your question about continuing on to Finisterre in a different section of this forum -- a separate section dedicated to the camino from Santiago to Fisterre and Muxia. Go here and you'll find lots of information: santiago-to-finisterre-and-muxia/

I think most people walk Santiago to Finisterre in three days, and then one more for Muxia. I've done that, and the group I was with agreed that it would have seemed more fitting to end in Finisterre, that is going Santiago to Muxia to Finisterre. I may try that this year, but the one drawback I see is that if you go first to Muxia, you will miss the incredible walk along the water and towards the water on the path into Finisterre. I suppose you could walk a circle and see it all!

I don't think a separate guidebook is necessary, it's extremely well marked and you can find out all about the services along the route in the part of the forum I linked to above. You don't have a lot of options on this route, so everyone winds up stopping in the same places.

You get the compostela at the Cathedral in Santiago, and both Finisterre and Muxia have their own "certificates" they give to people who have walked from Santiago. The hospitalero in Muxia is reported here to be a bit per-snickety about giving out the Muxia certificate, so if you go to Muxia be careful to get stamps along the way.

Buen camino, Laurie
