From Tavira to Santiago de Compostela is about 960km. Caminho Nascente connects Tavira with Trancoso, approximately 2/3 of the way - 660km - from where it follows Caminho de Torres, which starts in Salamanca.
I have just started from Tavira and walked as far as Évora, about 264km in 9 days. Did not see any pilgrim and there is little ready for pilgrims. But it's stunning. It resembles at times Via de la Plata, but can you believe it, it's even more remote at times! Let's see what the future says about the rest of this caminho.
