<P> From its confluence at Cefn - coed - y - cymmer , the river flows south , passing several towns . It picks up a few tributaries , such as the River Cynon , River Rhondda , Bargoed Taf and Nant Clydach . It flows through Pontypridd and through to Taff 's Well , the site of Wales ' only thermal spring . It flows underneath the M4 Motorway , before turning southeastward and flowing through the Cardiff suburbs of Radyr , Whitchurch , Llandaff , Pontcanna , the city centre and Grangetown , before emptying into Cardiff Bay , near to the mouth of the River Ely . </P>
