Hello, there's the Camino Verde that leaves Lugo and heads over to Friol and then to Sobrado. There's also an alternative that takes you towards the Frances and joins it right at the airport instead of Aruza. I have provided a view to this alternative on the Camino Verde site here on Ivar's forum;

We've done the Primitive twice this way and it was beautiful and is very quiet compared to joining the Frances. In June we encouraged a number of our Camino family to go this way and many of them did. They had nothing but great things to say! Meanwhile a few we knew that went down to Melide said walking into Santiago on the Frances was like walking around Disneyland.

There's some really lovely places to stay and we'd be happy to provide some recommendations if you decide this is the route for you.
