DEFINITION
Routes that connect places related between them because of historical,
social, economical or artistical reasons. They can have an special mark
to recognise them or can use other kind of marks. They have been created
to be made by foot.
When the route does not have an own marking, it is used the generic one:
two yellow-and-green rectangles of 130x50 mm, that, overposed, indicates
the route to follow; when they are in a cross, they indicate the wrong
route.
They can coincide or not with other routes. If this is the case, it is
shown in the description.
