the navigation starts in wakefield, where there is an end-on junction with the aire and calder navigation and runs upstream through mirfield, after which there is a junction with the huddersfield broad canal, to arrive at sowerby bridge, where there is another end-on junction, this time with the rochdale canal. other towns on the navigation are horbury, dewsbury, brighouse, and elland. the former branch to halifax is no longer navigable, except for a stub now known as the halifax arm. a sign clearly signposts the halifax arm to the right, and onwards toward sowerby bridge as you emerge from the top lock.
