ALT A map showing the route of the Taff, from Merthyr Tydfil, through Treharris and Pontypridd, down to Cardiff, as it empties out into the Bristol channel.

ALT The River Taff from above, with rushing water above Radyr Weir in Cardiff, and still water below. A train runs alongside it, and shadows in the water suggest a dozen or two fish.

ALT The River Taff from further down next to the Millenium Stadium's walkway, with graffitied walls alongside it and scruffy banks of vegetation on the edges.
