The Royal Geographical Society has created its first audio guide in Wales to tell the tale of how the Rhondda and Cynon Valleys were shaped.
The walk has been inspired by Jennifer Lewis, who made the trip from her home in Australia to retrace the footsteps of her grandmother who lived in both Valleys.
