Ships as large as this one still use these markers to find the deeper entrance channel of the River Clyde allowing them to travel further up river towards the city.Due to storm damage and low level maintaince this barrier has a wild and forlorn look about it,as exposed , remote and battered as any mountain summit.With the tide rushing in it becomes an interesting and committing adventure
If walking out to the markers please insure that you are aware of the tides and have approprate foot ware
