There are no four-letter rivers in Cardiff.
The River Taff is the longest river in Cardiff, but it has five letters. It flows through the heart of the city and is an important part of Cardiff’s history and culture.
The Ely River is another river that flows through Cardiff. It is a smaller river than the Taff, but it is still an important part of the city’s natural environment.
Other rivers in Cardiff include the River Rhymney, the River Tonteg, and the River Severn. All of these rivers are longer than four letters.
So, while there are no four-letter rivers in Cardiff, there are still plenty of rivers to explore in the city.
