On this website there are different types of routes that pass through and fraternize border passes used since time immemorial by the inhabitants of the adjoining valleys between Spain and France, and others that run through spectacular valleys.


These routes may have different types of sign posts and it is important to know them because they indicate the continuity and direction of the route.
