Taffs Well is Wales’ only natural thermal spa and although it is situated adjacent to the Taff, the water that now bubbles up here has taken over 5,000 years to filter down from the Brecon Beacons and is warmed geothermically by the Earth’s mantle. In general, the temperature of rocks within the earth increases with depth, thus raising the temperature of the water that comes into contact with it.  There is an audiovisual presentation in the lovely grounds of the park and a cafe will shortly be opened by local volunteers.
