Welsh resort's babbling brook? (4)
I believe the answer is:
rhyl
'welsh resort's' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for rhyl that I've seen before include "Seaside resort in Denbighshire" , "North Welsh resort" , "Clwyd resort" , "Welsh location" , "N Wales resort" .)
