The River Morar must be a contender for the shortest river in Britain. From its outflow from Loch Morar until it becomes tidal in Morar Bay it is less than a kilometre long with a drop of ten metres. A rock step prevents the loch completely draining into the North Atlantic.
In its short length the river is bridged by both the old and new roads to Mallaig and by the West Highland railway. The photo shows the Morar flowing over the rock step into Morar Bay just downstream of the concrete railway bridge.
