Now that you have reached Santiago de Compostela, why not continue a little bit further, up to the End of the World in Finisterre? And just two more walking days after, to be able to discover lovely Muxía!
The way to Finisterre & Muxía will take you to the Celtic and Roman traditions of Galicia region. You will be able to discover the Costa da Morte (the Coast of Death in English), one of the most unspoiled regions of Spain, very popular because of its cliffs.
Once in Muxía, do not forget to get your Muxiana (the Pilgrim Certificate for those brave pilgrims who get there) and taste some delicious seafood!
